I assume this line have DOS end lines.

You try import it using Cursor,ImportASCII() ?

Have you specify line delimiter to be \n ?


Please download Valentina studio and subscribe to its list.

Use Valentina Studio to create simplest table with say 2 fields and 5
records.

EXPORT it into ASCII coma separated.
Jochen, can we do export ?

Hi Ruslan,

I saw your Index_String test results.  Congratulations!

I have been working on some early concept ideas for a new project and I
remembered something you said about Valentina 2.0 as quoted below:

<quote>

Hi All,

I think we will start to grow list of new features that we have
implement on
2.0 engine.

Igor, Alex, Sergey, Ivan, Yuri, please participate in this.
I will start below template of list, and let's grow it.
Everybody know his tasks so mention them.

So, this is FIRST DRAFT made in 10 minutes by me.


-----------------------------------------------------
KERNEL
-----------------------------------------------------

* RAM-based database

</quote>

Does this mean the entire database will be able to exist only in RAM
with nothing written to the disk?  If so, will there be a way to create
a database in RAM and then, if desired, write the database to disk?  If
not, I would like to make a feature request :-)

As you know, I'm a V4RB user, so something like...

vdbData.WriteToDisk(inFolderItem as FolderItem)

...would be nice.  The opposite would be nice also...

vdbData.WriteToRAM()

...this would take a database that exists on disk and create a RAM-based
version of it.

I would not be doing this for speed reasons...Valentina is plenty fast.
It is hard to explain how I would use this.  I just got the idea for
this project on a plane flight last week and I still do not have a good
picture of how the software would work, but I believe these features
would really make my idea easier to bring to reality.


Also, while I have your attention, I have been looking at the new Vsets
and Vlinks.  Very nice!!!  I was wondering if Vsets are going to work
with Valentina Server once it is converted to work with the 2.0 kernel.
If so, will we be able to declare Vsets as Server-side or Client-side
similar to Vcursors?  I can imagine creating several Vsets Server-side
then creating a Client-side Vset that is the intersection/union of the
Server-side Vsets so that most of the work is done on the server then
the result set that I want is returned to me so I can work with it
Client-side.

I'm just trying to get my head wrapped around these great new features!

Thanks for your time.

- John

Yes, and you should understand that db must fit into YOUR computer RAM.

Not implemented, but yes this is good feature.
And later raise from disk to RAM.

Correct. In similar way work RAM based dbs.
They work many hours in RAM but can make image on disk.

> I would not be doing this for speed reasons...Valentina is plenty fast.

But RAM-based database will be even several times faster!!!!!
5-10 times I think.

Also note, in regular disk based database we will be able do
    TMP RAM-based small tables.

Yes, we have decide put all this functionality to Vserver also.
This have sense at least for fast intranet network.
If you have 1Gb network, then it will act not slower of HDD.

Not on start. We also have think about this.
Require time to implement.

Exactly!   you watch directly into ROOT! :-)

Such feature will allow us reduce network traffic.

Sets and Links this are tools of Navigational Model in the first turn.
Having server-side sets and ability do operations on server,
We can be effective almost as SQL and cursor.

Although to be exactly effective as SQL or even better we need server-side
scripts based e.g. On Phyton or Java

According to your project

1) we have fix bugs in cursor.Delete()

2) and I right now have practically finish Index_String.
I have spend almost 2 weeks on this task. And I need more tests for it yet,
but I think bugs are fixed, so these new test will go fast.

Oh! testes have finish!

Having this, we will make new beta. I think tomorrow.

    Also we will make new V4MD WIN beta, where will be 2 new examples
    -- pictures, images
    -- binding 


Next my task:
- Field.CaseInsensetive() flag.


Actually we have found that we will do this in the next way:

    Vfield.Collator as integer

As far as we see it, we will have 6 levels here.

    0 - no affect. Build case-sensetive index like in V 1.x

    next 5 levels define case insensitive index as we have told before.
    also some levels affect accents chars and so on.


And after that I will need make working flag IndexByWords for String,
VarChar and Text fields.

Hi Ruslan,

I get a "field not found" exception with this query:

select id,hit,uniqueID,authors,thedate,title,editors from 
thereferences ORDER BY authorsSortMethod

Am I using a reserved word for a field name


  Or is the authorsSortMethod the problem? It is declared as

authorsSortMethod = CreateTextField("authorsSortMethod", 128, 
"English", Valentina.fIndexed, "Upper(authors)")

Thanks,

There is a space where the field name should be, I think.

Here are the last few lines of the log:

DataBase_SqlSelect...
	PARAM: instance = 26531596
	PARAM: inQuery = "select 
id,hit,uniqueID,authors,thedate,title,editors from thereferences 
ORDER BY authorsSortMethod"
	PARAM: inCursorLocation = 2
	PARAM: inCursorType = 1
	PARAM: inDirection = 2
return object = 0

return object = 0

May be because you have BLOBs in cursor ?

Ruslan,

What is the second parameter for .EscapeString for? Since it is named 
inforRegEx I assume you should set this to true if it's a REGEX 
search, but to false if it's a regular SQL search. Is this correct? 
What does it do, exactly?

Thanks,

Let me remind.

Valentina 2.0 use SQL92 standard LIKE,
I.e. You can use only chars  % and _

    WHERE fld LIKE 'fff%sss _bbbb'


To get power of REGEX syntax you should use new keyword

    WHERE fld REGEX  '\Abbb'
    WHERE fld REGEXP '\Abbb'
    

For regex we need escape more symbols

        ( ) . ^

Btw,

As I understand you use in your project escapestring() ?


Where and when you use it ?

I think that you can try to use instead SQL BINDING.
This will do work easier and faster.

In the SQL folders you can find example Binding.

I use EscapeString for all my indexed searches. I never heard of SQL 
binding -- I'll take a look.

Hm, I don't see how I would use this for searching indexes 
indexedbyword. But it does bring up a question about .escsapescring:

If I do a SQL search of an indexed (by word) field, it's for the name 
O'Shea, would I first

s = Valentina.EscapeString("O'Shea", false)

and if it's a Valentina REGEX search

s = Valentina.EscapeString("O'Shea", true)

And what would I do for a SQL LIKE search?

I guess I'm asking how V2.0 is going to handle indexes...

Thanks,

Jon

Yes, because you will need build SQL string of query which looks

    "...WHERE fld = 'O\'Shea'
                      ^^^^

If you will not have ESCAPE on apostrophe, then how parser can know that
this apostrof is not the end of string constant? You see?

Also 

   s = Valentina.EscapeString("O'Shea", false)

Easy

You write not 

    s = Valentina.EscapeString("O'Shea", false)
    q = "select ... WHERE fld = '" + s + "'"

    db.SqlSelect(  q )


With bind you can write:

    q = "select ... WHERE fld = :1"

    arr.addItem( "O'Shea" )

    db.SqlSelect( q, arr );

We win here that 
1) we do not do escape string, instead ZERO TIME
2) we do not concatenate query string, instead ZERO TIME.
3) parser work on smaller query string, so less time.
4) parser do not convert escaped string back, instead ZERO time.

In V1.x I could ORDER a cursor by a field I did not select.

It seems that this causes an error in V2.0. Is that correct -- it is 
no longer allowed and you must select the field you ORDER by?

And secondly, if so, I think this might be the cause of the "field

Hmm, as I remember, on start Valentina 1.x did allow this.
Later when GROUP BY was implemented Valentina 1.x also prohibit this.
So are you sure that in Valentina 1.10 you could do this ?!

And yes. SQL92 do not allow this.
Because ORDER BY sorts NEW result table in general case.

Because ORDER BY also have syntax

    ORDER BY 1, 2 

To refer fields from SELECT rule.

Ivan,

Add Please test 

SELECT f1, f2
FROM T
ORDER BY f3

And check what error is throw,
And it seems that error message do not display name "f3"

Tests are added and passed correctly.

1.
SELECT f1, f2
FROM T
ORDER BY f3

2.
SELECT f1, f2
FROM T
ORDER BY 3


Some minor changes have been done in the Node_Select_OrderBy_Elem node
and void Node_Select::DoSorting( void ) method.

Yes, both tests are in the error-tests area.
Both tests generate xFieldError exception.

Yes, I have examples where it works in 1.x (I don't ever use GROUP

Hi Ivan,

If f3 is a correct method that manipulates data retrieved from f1, 
does that throw an error, or does that work?

FYI, I just tried this in my project -- the error string does not

It does not matter what is field you are using.
Order By just checks that ordered name is from the select list.

Example:

select f1 as ff from Table Order By f1

Here is exception due to the SQL standard. Because no field with name f1 in the select list.
There is "ff" name.

First of all.

Valentina 2.0 uses OTHER error codes that Valentina 1.x.

IF you have in your code

    if( errnumber = 344 ) then

This is very bad and must be fixed to use Error constants.

Well, it seems I have not yet enable constants in V4RB 2.0.
I want generate them automatically from our XML files.

Interesting.

I will test

OK, Ivan, I see. Then how do this:

I have a method for each field so that I can do a case-insensitive 
sort. The name of the sort method is the name of the field + 
"SortMethod". For example, to sort Authors, I have a method 
AuthorsMethod.

Here is that method definition:

  authorsSortMethod = CreateTextField("authorsSortMethod", 128, 
"English", Valentina.fIndexed, "Upper(authors)")

Here is how I have used it in Valentina 1.x:

myCursor = myDatabase.SQLSelect("select id,authors,thedate,title,hit 
from thereferences ORDER BY authorsSortMethod", 
Valentina.kServerSide, Valentina.kReadOnly)

What is the best way of doing this in Valentina 2.0?

Thank you,

Jon

1) you can SELECT AuthorsMethod to be last field, and ignore it in your code


2) MAY BE later we will again allow ORDER BY for not selected field for
cases where this is possible. E.g. Single table query, as your.


3) the BEST WAY in 2.0 for your project will be next!

 * you will REMOVE at all your method fields!
 * so your table will have not 70 fields as now but 35 fields.

You will get the same functionality using new feature

        Vfield.CollationStrength = ...

So be prepared!
Your project and tables will become much more simple now.

It could be great if you could wait just a little and start with Valentina
2.0. 

Or start right now with Valentina 1.x but in the nearest time switch to 2.0.

I recommend you go to our support page and subscribe to Valentina beta list.
You will be able then review V4RB 2.0 beta.
It have many new cool features.

Well, I see.

Igor have spend last 3 weeks to incredibly improve Vpicture field!
Especially for Director.

Subscribe to beta list, when I will see that,
I will forward today's Igor letter to beta list.

In short, 

Now VBLOB and Vpicture have functions

    blob.LoadFile( path )
    blob.UnloadFile( path )

Also with Picture class you can simply READ and WRTIE an existed JPG, GIF,
TIFF as is. Without any compression on Valentina side.

---------
Next, yes, in the nearest time, I will improve VBLOB field in the V4RB to
work not with String only but with MemBuff.


--------
Scott, also I wonder, why you wonder about PICT/DIB.
When Valentina extract picture from db it MUST give to REALbasic or Director
a PICT/DIB.

REALbasic do not want to get from us JPG. You see?

How you image to self that Vpicture return TO YOU a jpg ?



------------
Using VBLOB.LoadFile() you have no more easy way to store into db movies.
And you can extract ONE movie to disk to play it, then erase.

Yes, it will be more cool to have MOVIE field, which self establish stream
to Quicktime and load movie by small parts during playback.
We will not be able do this in Valentina 2.0. No time.

Subject: Dealing with 1.x databases
Message-ID: <p06002001bd3be53c19c1@[216.194.229.73]>

Hi Ruslan,

One question, one problem.

1. When I open a 1.x database with my 2.x project I get a -39 error 
(end-of-file). I can trap for that and give an error message, etc. 
But a -39 error can occur for other reasons (like a corrupted db). 
Will this error be changed to something more specific to Valentina 
(like a VError of 'version too old', or something like that)?

2. I trap for this error and back out gracefully. But when I try to 
open another database afterwards (even a good, 2.x version) Valentina 
immediately crashes on the line

	myDatabase = new myDatabaseClass

There is no crash log generated by the system. And I don't see 
anything written to the Valentina log, either.

Well, yes we must throw error here.

Ok. In first turn above error should be fixed.

Hi Brendan,

I have CC this to Valentina beta list, and I think your question is for beta
list, right?

It seems we already have discuss this few weeks ago.

You can answer to that boy:

1) any modern COMPLEX product is built on component architecture.
    This is why was born COM and CORBA.

2) in complex projects
    (and Valentina 2.0 is VERY complex project I should say,
    it have more than 1000 files)

Developers use component architecture on many important reasons.

* in project can be used THIRD PARTY SDKs, tools, ...
    and it will be unreasonably hard tune that SDKs to be compiled
    in OTHER way than original developers have made.

    For example, we use IBM ICU library for unicode.
    this library Is even more complex that Valentina 2.0 itself.
    IBM guys have made it as 3-4 DLLs.
    I hope you won't ask that Paradigma Software have tune IBM's
    SDK to make it as LIBs. This is possible I think, but may take
    a lots of time.
    

* second reason for component architecture is that components are
    INDEPENDENT parts of engine. This means that we can do TEAM development.
    
    This is VERY VERY STRONG REASON.
    Design of Valentina 1.x was good for single developer, but we have meet
    problems trying to work in team with Valentina 1.x.
    This is why we have re-write from scratch Valentina using
    modern new design.

    By my estimates, in ONE YEAR our team have made project by size
    5-10 developers-years.


* COMPONENT architecture allows for third party developers
    develop/distribute/sale plugins for Valentina engine itself.

    Is this good? IMHO this is great!
    Brendan, image that REALbasic will not support plugin system.
    you an tell me that REALbasic still pack all in on exe file.
    well, as far as I know, only REALbasic do this.
    Director, Revolution, ... DON?T.


* COMPONENT architecture allows at last of end, to YOU as Valentina
developer use only that components which are required in your application.
Our target is that e.g.
    * if you do not want picture in your db, simply remove few DLLS that can
        be 500-1000KB.
    * if you do not want SQL, but only Navigational Database model,
        remove VSQL.dll and size of engine will be reduced in 2 times.
    
This is not implemented, but  this is our target.


Now look what you want suggest:

    IBM ICU          DLLs about 5MB total.
    IBM .dat file    3-8MB
    Pictures         500KB
    Vengine          3.5MB

If we will link all this into single file, we easy come to 10-15MB.
For single platform.

I think this is not good. Not flexible.


* Another advantage of components. As I have told the fact that in V4RB 2.0
engine is REMOVED from plugin itself, we can easy and effectively provide
you 2 versions of V4RB/V4MD plugin: DEBUG and RELEASE.

    DEBUG version will have A LOTS and AS MANY AS POSSIBLE
        different debug checks, log files, and so on.

    RELEASE will be compiled absolutely without this code,
        so it will have ZERO overhead.


----------
And again.

We will be able provide you way that you -- DEVELOPER,
Will give to your clients _single_file_ application (on MAC).

        MyGreatApplication


Yes, yes, yes. Using packages.
This is modern and standard of Apple

We already have told about this:
    open your folder "Applications".
    and check such apps as iTunes, iDVD.

They looks as SNGLE file. Users are happy.
But open package. Here a lots of files.

So why Valentina must not go by this way ?????????????????

What ever happened to implementing GetFileVersion function in 1.10? 
This was last discussed when version 1.9 came out if I recall. We 
should be able to inspect version number and determine whether it is 
valid or not.

Robert,

It is time to remind us ANY features you have dream.

Yes we will add GetFileVersion()


Also I remember you have had ideas about Encryption API.
We have not come to encryption yet.

So soon we will ask you,

If you have time you can write specification of your dream :-)

Message-ID: <A67C62CC-EBA4-11D8-98CF-000393DC4766@vermontsoftworks.com>

Hi, Ruslan --

I'm experimenting with binary links in V4RB.

I've created two tables: tblAdmin and tblAffiliation.  I'm attempting 
to link them 1:1 with the following code:

==========
Dim vl as VLink

if link("linkAffiliationAdmin") = nil then
   try
     vl = CreateBinaryLink("linkAffiliationAdmin", tblAdmin, 
tblAffiliation, valentina.kOne, valentina.kOne)
   catch vExc
     Except(vExc, "Unable to create Affiliation/Admin link.")
   end try
end if
===========

This gives me error #339968: "Insuffucuent resources."

Any ideas?  Oh, and FYI, it should be "Insufficient," not 
"Insuffucuent."

Many thanks,

-- Erik

Okay, I see where is problem.

You try to work via Classes way, i.e. Static way.
You create tables and link BEFORE you have do db.Create()

Right now primary our tests targeted to DYNAMIC way,
I.e. Db is opened and we tell it create/drop objects.

Classes way is more hard, and not all parts work yet.


So you can try to use BinaryLink without classes.

I'd like to, but I don't see yet how to get a persistent database with 
your dynamic method.  There are many examples of dynamically creating 
and dropping tables, but I haven't been able to find any example that 
shows how to open an existing database with this dynamic API.

I love the idea of dropping the objectptr fields -- and, even more, of 
dropping my many-to-many link tables.  My new database would have about 
a dozen 1:M relations as well as another dozen or so M:M join tables, 
and it would be GREAT to replace these with direct binary links at the 
database level.

So will there be -- or is there now -- a way to get this persistence 
via your new API?  Or should I stick with the older class method?  And, 
if I need to stick with the class approach, will your new binary links 
work with it?

Thanks for any clarification you can give!

Hmm, very simple

    dim db as Vdatabase

    db.Open()


Now you can do 

    tbl = db.Table( "name" )
    fld = tbl.Field( "fieldname" )

The same was in 1.x

Just no classes.

Absolutely right.

Here few benefits

1) binary link will be more effective and eat less disk space than M:M ink
table.

2) design of structure become more natural.
    Tables (objects) do not have intrusived pointers to OTHER tables.

Right now as Relational model, so ObjectPtr fields, require from you CHANGES
of some Table if you add/remove link.

Using Binary Link, we have STABLE and CLEAN definition of tables!!!
I think this is the biggest advantage of Binary Link,

Yes, of course I must make that YOUR example with classes way will work.
I will try to fix this on this week,

Hi All,

Right now I work on implementation of the next new methods

Class Vdatabase, Vtable and Vstring/VarChar/VText
Will get next 3 properties

    Locale  as String
    Encoding as String
    CollactionStrnegth as Integer


The game start in database.

* when we create database it get on default system settings,
    Or we can set what we want.
* when we create table, it inherit settings from db.
* the same for field, it inherit it from table.


So if you want to use the same settings for the whole db, you simply specify
them for db. And do not care for fields.

You can have some table(s)/field(s) with other settings.
Settings of course are stored in the system tables.


Example:

    Locale:  "en_US", "en_GB",


    Encoding: "UTF-16", "UTF8", "Western MacOS Roman", Latin-1,
                Cyrillic(Windows), Windows-1251, ..


    Strength:

  /**
  * Base letter represents a primary difference. Set comparison level to
  * PRIMARY to ignore secondary and tertiary differences.<br>
  * Use this to set the strength of a Collator object.<br>
  * Example of primary difference, "abc" &lt; "abd"
  * 
  * Diacritical differences on the same base letter represent a secondary
  * difference. Set comparison level to SECONDARY to ignore tertiary
  * differences. Use this to set the strength of a Collator object.<br>
  * Example of secondary difference, "?" >> "a".
  *
  * Uppercase and lowercase versions of the same character represents a
  * tertiary difference.  Set comparison level to TERTIARY to include all
  * comparison differences. Use this to set the strength of a Collator
  * object.<br>
  * Example of tertiary difference, "abc" "ABC".
  *
  * Two characters are considered "identical" when they have the
  *  same unicode 
  * spellings.<br>
  * For example, "?" == "?".
  *
  * UCollationStrength is also used to determine the strength of sort keys
  * generated from Collator objects.
  * @stable ICU 2.0
  */
  enum ECollationStrength
  {
    PRIMARY    = 0,
    SECONDARY  = 1,
    TERTIARY   = 2,
    QUATERNARY = 3,
    IDENTICAL  = 15
  };

So if I want to ignore case but I want to 
consider accents (a <> ?) I would set the 
strength to secondary?

And if I wanted to ignore accents, too, I would set it to...tertiary?

No, here reverse logic.
I also have catch not from start.

    tertiary -- this is like in Valentina 1.x.
                aaa <> AAA
                aaa <> ?aa

                upper(aaa) => AAA
                upper(?aa) => ?AA


    SECONDARY -- ignores difference between Diacritical chars
                 i.e. Secondary difference of chars.

                aaa <> AAA
                aaa == ?aa

                upper(aaa) => AAA
                upper(?aa) => AAA

    PRIMARY -- ignores difference between case of chars
                 i.e. Ignore primary difference of chars.

                aaa == AAA
                aaa == ?aa

                upper(aaa) => AAA
                upper(?aa) => AAA

Well, Jon,

It seems I self still not understand its rules completely.

I think we will play with different settings,
And will see how it works.

You use secondary strength.

Tertiary considers base/diacritic/case differences but ignores lower-level
ones.
Secondary considers base/diacritic differences but ignores case and other
lower-lever ones.
Primary considers base but ignores diacritics/case etc.

Please see http://oss.software.ibm.com/icu/userguide/Collate_Intro.html

Added 2 new methods.

    VBLOB.FromFile( location as FolderItem )
    VBLOB.ToFile( location as FolderItem )


This function allow you easy LOAD/UNLOAD disk file into BLOB record.

It store only content of file.
But not its name and path.
Because usually you will want unload file on other computer into other
location.

I think it will be reasonable always use in pair a String field, that will
contain NAME of that file (may be partial path.)


LIMITS:

* not store resource fork of MacOS  file
* not store yet additional info (flags, creator/type, ...)

Valentina dump in an XML file any BLOB field as HEX values.

For regular BLOB this is required. There is no way express BLOB value and
pictures into text form.

But for TEXT field, yes, we can also dump readable chars....
Just nobody have complain on this yet.

Aha, I remember why I did not use chars.
Look.

TEXT field can contains multi-line text value.
I.e. We can have many new lines. So text file can looks as

<f n="*description*">Aha, I remember why I did not use chars.

------------------


Hmm, well, not so bad...
Okay, I think in Valentina 2.0 we can change this behavior.



Btw, Daniel, 

    "*description*" -- this is name of field?


Not good. You should start names from letter or digit or _
Valentina 2.0 will complain on such bad names.

Igor, first of all we must find solution to return symbols.
Above example is not good, because it have different syntax.

Yes, if we will be able return symbols then I prefer

    Valentina.DoSomething()

    if( ValentinaError() != #ERR_SUCCESS )


Interesting, can 2 Xtras in the same project conflict if they use the same
symbol? Please ask on Xtra list.

This letter CC'd to beta list.

Let me describe how I see it.
Correct me if I am wrong somewhere.
Add own ideas! 

1) I believe that all new databases (using Valentina 2.0) must have
   db.StorageEncoding as

        UTF-16   (in the first turn Japan, Korea, ..)
    or  UTF8     (Western languages, Cyrillic, ...)

Valentina 2.0 will allow also specify to keep files on disk in e,g,
    Cyrillic WIN (1251)
    Cyrillic (KOI-8)
    Mac Western
    Latin-1
    ...

But I do not see any strong reason for developers to do this.
Better to use Unicode.


2)  db.InputEncoding and db.OutPutEncoding

* They also can be on default UTF-16 or UTF-8.
    i.e. Developer can simply say:
    I work with UTF16 or UTF8 and that is all.
    any headache. 

* Developer can specify here,
        (and I think few years yet this may be widely used)

   some other encoding. For example:
   I want store info in db files UTF8 encoding, but
   I want do I/o using Latin-1.
    
   Or I want Input in Latin-1 but output in Mac Western

In this case it will work as next,

                   
    input in Latin1         output in Mac Western

     ------------> + ----------------->
                   |
                   |
            +---------------+
            | Vengine use   |
            | always UTF16  |
            +---------------+
                   ^
                   |
                   |
           
            disk file (UTF8)
        

As input/output I mean such functions as

        fld.SetString( "asdfa" )    // Latin1
    s = fld.GetString()             // Mac Western



I think I talk now mainly about C++ SDK.
Because e.g. REALbasic developers now mainly get/set strings in UTF8.

Director MX give to Valentina MacWestern and Latin-1 __always__.


I think above is the most flexible way.
Anybody see what else here can be made as option ?

Subject: [V4MD:DONE] Valentina Xtra
Message-ID: <mailman.1.1092843604.5898.valentina-beta@lists.macserve.net>

Hi team,

I've done with Valentina Xtra.
So now this Lingo code is working:

    global Valentina

    on startMovie
        global Valentina

        set Valentina = Xtra "Valentina"
        if (objectP(Valentina)) then
            Valentina.initialize("", 8 * 1024 * 1024, "", "")
            if( Valentina.getLastErrorSymbol() <> #ERR_SUCCESS ) then
                alert("Something wrong there!")
            end if

            Valentina.shutDown()
        end if
    end startMovie

This is the whole message table for Valentina Xtra:
++++++++++++++++++++++++++++++++++++++++++++++
"xtra Valentina\n" \
"new object me\n" /* standard first handler entry in all message tables */

"+initialize object me, string componentsPath, integer cacheSize, string
macSerial, string winSerial \n"
"+shutDown object me -- Closes all opened databases and destroys cache\n"

"+getVersion object me -- Returns the version of the database engine. \n"
"+getCacheSize object me -- Returns the size of the cache. \n"

"+getLastError object me -- Returns error code of last Valentina method.\n"
"+getLastErrorString object me -- Returns error string of last Valentina
method.\n"
"+getLastErrorSymbol object me -- Returns error as a symbol. \n"

"+setDebugLevel object me, integer Level, *-- integer UseMsgWindow.\n"
" -- Sets debug level for V4MD (0-no debug, 1-errors only, 2-functions).\n"
"+getDebugLevel object me -- Returns the debug level for V4MD. \n"

"+logToMsgWindow object me, integer on -- Enables or disables logging to the
Message Window. \n"
"+logToFile object me, integer on, integer flush -- Enables or disables
logging to the file.\n "
" -- If on <> 0 creates 'V4MD_Log.txt' file and logs messages to it. \n"
" -- If flush = 1 then does flush after each log. \n"

"+setExtensions object me * -- List of extensions, e.g
[\"vdb\",\"dat\",\"ind\",\"blb\"].\n"

"+escapeString object me, string str, integer forRegEx -- Escapes given
string. Set forRegEx to 1 if str is a RegEx expression.\n"
++++++++++++++++++++++++++++++++++++++++++++++

As you can see all the method are 'parent' (same as static in C++)
So we do not need to create any instances of this Xtra - it is available
globally in any movie.

P.S. Now I'm moving all baseobject methods into VTable Xtra but I'm not
finished with this yet.

Yes Igor!!!!!!!!!!

That?s the point!


Having this *_NEW_* design of V4MD we can easy provide all features and
functions that we have in e.g. V4RB.

This is really great!

At last of end, I think exists Director developers which also want full
control on Valentina engine and which are ready to do this.

Yes, you are right of course.

I think we all dream about day, when C++ will get ABI standard,
And all major compilers will support it. I think we can hope on this in the
nearest 5 years.

Excellent to know that you have such goal!

Yes. If I am not mistake on windows this is developer responsibility take
care to correctly choose API compatible to v. XXX

Apple have provide us SDKS for different OS versions, and I cannot do
mistake.

Aha, I see.

So ICU allow disable name versioning?
I did not know this.

Good point. I see.
Actually we have use C++ classes of ICU.

Well, this is possible only for Macho and only for GCC apps.
We use also CodeWarrior and we make also Carbon apps.

My original question was: IF we can use our own CW dlls, but use only .dat
file from MacOS X. It seems to me this is bad idea. It can be broken in
future versions.

Yes, your points should work of course.

Let me add. You have not point WHY we need mColumnIndex.

When I have start read this, I have told self:
    Hmm, why we need it?!
    we can get this from position of field in Array.

Few seconds later I have to see why:
    on open we read files in physical order from sys tables,
    then we need sort by that mColumnIndex.

This should be mentioned in Comments, Ivan.
Other people also can wonder why?

Good.

IMPOANRT POINT, 

What about names of Field files ?!!!

Add the next test:

* you must add say 10 records into table with different data in columns.

* after above changes and close/open make sure that you read back the
CORRECT data.

If you will find that data are wrong then problem and solution is next
    (we have discuss it on seminar)

- in the name of embedded field files, must be use Field_ID, but mot Field
Index. Because Field_ID never changes for a field during its life.

Please check this.

Hi Igor,

very nice, I've always done file logging manually for clients that are
debugging my apps, now this will be much easier to do. Thank you :-)

Hi Igor,

since you stripped the comments, can you explain the
"putRecID" method?

Why are you using "put" instead of the get/set syntax
used in the other methods?

When would you need to set a RecID and why, they
get assigned automatically anyway and since they're
unique it would probably return an error in most cases?

Martin.

This is stripped comment:
"Goes to the specified record. In the case this record is deleted, returns
FALSE
and do not changes current record."

> Why are you using "put" instead of the get/set syntax

This is my mistake, of cource. I've already changed it to setRecID().

This is like Goto record with RecID = nnn

Good point.

Igor change this.

Put/get this is our C++ names

Subject: V4MD: Big changes in design!!!
Message-ID: <BD4A8DF2.221FA%sunshine@public.kherson.ua>

Hi All Director users!

2 days ago we with Igor have got idea how to significantly improve and clean
up design of V4MD.

V4MD 1.x do have 2 Xtras. From point of vie of other programming languages
it have 2 classes.

Vdatabase Xtra was very overloaded by API.

* it have global methods.
* it have methods of Vtable class.
* it have methods of Vfield class.


In V4RB 2.0 we have add new classes: Vlink, Vset, ...
And we was going NOT add them into V4md.
Because only way was add them again into Vdatabase Xtra.
Not nice.


Well, now we do next:

* we have main Xtras Vdatabase and Vcursor.

* global methods are moved to Valentina Xtra.
  so we will do

        Valentina.Init()
        Valentina.ShutDown()
        Valentina.Error()


* We extract methods related to Vtable
    from Vdatabase into new Vtable Xtra.

* We extract all field methods into new Vfield Xtra.

* We add much more new methods into Vtable, Vfield Xtras.

* We will add totally new Xtras: Vlink and Vset.


----------------

-- Having such design we get absolutely clean design of classes.
All methods are grouped in the correct classes.

-- Now V4MD will be not worse then V4RB and other Valentina 2.0 products!!!


Now, the main question.
Director developers can ask:
    why we need all this new functions and classes ?!

Answer is:

* Valentina support not only RDBMS model with SQL queries!
    
* Valentina 2.0 support also Navigational model, or we can name it
Object-Relational model. Or even better "Valentina Database Model".

This model combines the best features of

        Navigational model
        OR model
        OO model

And in the same time it establish absolutely new model, which is
    *combination* of features of that models plus some
    own unique features.


So. This new classes and functions allow you control, manage and search
database WITHOUT SQL at all!

In some tasks, Navigational model can be much more effective of SQL's way.

I hope describe all this in new Valentina docs.
Also we will provide a lots of new examples for V4Md now.

wow, sounds very promising, I'm happy to hear about the changes,
it makes total sense to adapt the RB structure and clean up V4MD.

at the same time this will probably mean there's no backward
compatibility with Valentina 1.x, right?

Martin.

Yes, will not be direct step.

But in any case few things developer was MUST correct

    LIKE -> REGEX

    unicode -> name of languages.

...
   

In the same time most changes - this is change of syntax.

So I think we will be able make list of Find/Replace.
May be even some automation script for this.

Hi Team,

Changes in CVS.
Please test them on your side.


I have made very simple example in V4RB, which create db with
StorageEncoding = UTF8.

I can see that VarChar fields of system tables correctly are in UTF8.
Actually they looks as plain English and Valentina 1.x db files.

* Now I need finish String and Text field in the same way as VarChar.

* Next, I will add into example creation of records.
    
* and of course I need make sure that all this I can open and read back.

Subject: [PROGRESS] V4MD Examples
Message-ID: <mailman.4.1093163803.5898.valentina-beta@lists.macserve.net>

Hi team,

Since there are many changes in V4MD public API 
then many changes to existing samples have been made to 
keep it working. This is the list of already updated examples:

    Common
        Init_Shutdown
        EscapeString
        SetExtensions
        ToFromDiskFile
        Database_CreateCloseOpen
    API_Way
        Table_CreateDrop
        Field_CreateDrop
        Records_AddUpdateDelete (practically rewritten from zero)

New external cast (ValentinaGlobals.cts) was created.
It contains 3 function:

    IntializeValentinaReferences()
    DisplayValError()
    CheckValError()

and defines 3 global variables:
    global Valentina
    global VTable
    global VField

Function IntializeValentinaReferences() must (or can) be then called from 
any movie to initialize global Xtras references on startup.

Also all the examples has been refactored to use unified error 
handling - exposed by last two functions 
    DisplayValError()
    CheckValError()

(so all examples now linked to this cast)

There are still not ready examples so I'm working on them now.

Hi team,

Subject is ready now.
Some new methods added to make it working to
VTable, VField, VSet, VSetIterator Xtra's that were not
exposed before, exactly:

    VTable.flush()
    VTable.selectAllRecords()
    VTable.selectNoneRecords()

    VField.find()
    VField.valueExists()

    VSet.release()

    VSetIterator.release()

and also many bugs fixed in VSet & VSetIterator Xtra's implementations.

Hi,

what does the "selectNoneRecords" method do?
And I would recommend naming it "selectNoRecords".

Martin.

Hi Martin,

A short words:

1) V4MD 2.0 will be able do SEARCH and SORT of tables without SQL at all!

    this, from one side position V4MD to V12 in good way.
    because sometimes (very rare actually) some developers say:
        SQL is complex for me.

But the main is that V4MD developers will get now access to the SECOND power
of Valentina -- Navigational model.
    
In this model we do not use SQL.

We do something as


    fldName = tblPerson.Field( "Name" )
        
    foundSet = fldName.Find( "Peter" )

    loop for each item of set
    
        RecID = set(i)

        tblPerson.GoTo( RecID )

        Now we can read fields of the current record.

    end loop

Also we have function to
    
    find all records from T1 linked to some record of T1.
    and more link functions

So we can search and sort single table,
We can find linked records as set.
And so on.

We work with Sets and Set Iterators -- new conceptions for V4MD.
And we navigate record by record.
This is why it is named Navigational.

And of course we can mix both models.


And one more. 
Navigational model for some tasks can be
in e.g 10 times faster of Relational model!

Hi Ruslan,

I'm familiar with the navigational model, I was just wondering in
which case you would want to select "no" records, maybe it's
just the naming of the function that I misunderstood.

Martin.

This function simple do

    return new VBitSet( table.get_PhysicalRecordCount() )


I.e. It prepare BitSet of required size for Table.

Usually, developer (and me too) forget that it needs to use here physical
record count and use Table.RecordCount()

To protect from this human mistake we have add this function.

uh...so a function with a name "SelectNoneRecords" returns
the record count? that doesn't really make any sense to me?!

No, it returns the BitSet with size equal
to physical record count in the table.


BitSet this is array of bits.

For example, if you have million records in a table,
Then we get BitSet in million bits = 128KB.

Hi All,

You can download b13 of V4RB.

[KERNEL][NEW]   
            Now in the kernel we have new planer of query.
            The most good thing is that now query of kind
                WHERE f1 > 5 and and f2 = 6 and f1 < 7
            will work. Valentina 1.x did fail here.


[NEW]       classes Vdatabase, Vtable and Vfield now
            have 3 new properties each:
                Locale as String
                StorageEncoding as String
                CollationAttribute

[NEW]       2 examples in the folder 'Common'

            one example demonstrate you inheritance behavior for above
            3 new properties. I.e. Table inherit settings from Database,
            and Field from Table.
            This example will be improved yet.

            Second example show creation of UTF8 and UTF16 db files.
            you can open them by hex edit to see that internally
            they really differ and use different encodings.


[CHG]       class Vcursor now DO NOT have property SqlString.
            we have decide that it is not correct to have it in each cursor.

Ruslan,

I know what storageEncoding and CollationAttribute are. What does 
Locale do? What is it for. And is there a list of locale constants?

Locale is   "language + Country"


    en_US
    en_GB

    ru_RU
    ru_US           russian in Ukraine // if any difference


Locale specify many things.
    upper and lower case it seems
    currency, date time // but we do not use this now

Hi Ruslan,

I can't even get started with b13.

Here's how I make a new database:

     tempDataBase = new myDataBase
     tempDataBase.Creator = "ABCD"       // optional
     tempDatabase.StorageEncoding = "UTF8"
     tempDatabase.collationAttribute = 2

     Valentina.ThrowExceptions = false
     tempDataBase.Create(f, 1, 2 * 1024 )
     Valentina.ThrowExceptions = true

     //Error checking, etc.
...


A file is created, but the folderitem.exists = false! When I try to 
open it -> crash. Here are some lines from the crash log:

A second, more minor, problem is that the creator is still set to 
VALA, not ABCD.

Does work my examples from Common folder on your side ?
2 examples with Locale prefix ?


--------
BTW, important.

Now ValentinaInit() really must be the first call to Valentina engine.

You cannot use before it even DeugLevel()

I do.

OK, more funny stuff. My preferences file is a Valentina database. 
When populating it I use a cursor to create records and set defaults. 
It crashes on the last line:

     myCursor = nil
     myCursor = new VCursor(prefsDB, "select textField from prefs 
where propertyName='gReferenceTypes'", Valentina.kServerSide, 
Valentina.kReadWrite)

     //do stuff with myCursor

     myCursor = nil

     // next line crashes....
     myCursor = new VCursor(prefsDB, "select * from prefs where 
RecId=0", Valentina.kServerSide, Valentina.kReadWrite)

I will check such query, but!

Official way for Valentina 2.0 to get empty cursor is

    ... WHERE false

Please try this.

Sorry, I meant I already call Valentina.Init first, so that's not the problem.

OK, I figured out one problem (silly, I should have looked at the 
example more carefully).

When you open a database you *must* specify the storageEncoding 
beforehand. If you don't -> crash. OK, easy to do. But why is this 
necessary? The storageEncoding is a property of the database -- why 
can't Valentina read it when a db is opened?

I have a table with 19 records. One of the fields is "propertyName", 
where I store the name of a variable, and the other field can contain 
the various values.

This search

   myDatabase.SQLSelect("select varCharField from misc where 
propertyName='groupName' ORDER BY varCharField"

returns all 19 records, even though only one of them has a 
propertyName of 'groupName'.

What is wrong with the select statement (or is this a bug in 2.0)?

Thanks,

Can I suggest/request that you put the VEngine inside the VComponents

they are both being updated constantly right now. Of course we still 
need to download the V4RB plugin separately because that needs to go in 
the RB plugins folder anyway.

Also, please put dates on the documentation below the downloads so we

I don't understand this change, can you elaborate why you are removing 
this? I admit that I have never used that property before, so I don't 
see this as a big deal.


Thanks!

But simply there is no any sense to do that.

If YOU have create cursor by some query then you already have that string.
And there is no any advantage to keep it in cursor.

I have see cases when developers have build SQL query in many KB.
So why spend RAM on useless thing ?

You mean PDF docs?

Actually, I have found it useful. Often I build a string in the query 
itself, and it is useful to see what the cursor actually "sees". It 
is certainly possible to create a fully formed string first for 
debugging purposes, but I (for one) have found it useful in debugging 
to see what the cursor holds.

Just my 2 cents.

For this I do it as next

    query = "... Where fld = " + str(id)

Now you can see real string query in debugger.

I think this is the only advantage.

I think bug.

This was usual database,
Or you have set UTF8 for it ?

Agree! this must not be required.

Otherwise how Valentina Studio will work?!

So I must store this info into system tables of course.

Hmm. This will not work, because when I read from sys tables I already must
know encoding. So it must go to header of vdb file...also not very good


solution: System tables always will be in UTF16 format.
    I think this easy to do because tables can have different format
    from database.

UTF16 doesn't work, either. All 19 records are still found...

BTW, I found another couple of issues with SQL 
searching (tell me if we're not supposed to be 
checking this yet).

1. If I set the .collationAttribute to 2, 
searches are case sensitive! I thought that the 
"secondary" case was case insensitive.

2. If I set the .collationAttribute to 1, the 
search finds every record in the database, 
regardless of what I type in.

3. Searches for words containing unicode 
characters (e.g. t?st) fail (.collationAttribute 
= 2, UTF-8 database).

Hi All,

You can download b14.

1) now It can open UTF8 database

2) viSQL project modified:
    Structure Browser window extracted into 'shared items' folder.

3) Example Locale_Records now use this Structure Browser,
    we can now easy see that after open we get back correct table and
fields.



----------
I think it is cool that we have now such shared items as

    - Structure Browser
    - simple Table Browser
    

Now me and everybody from you can in few lines of code plug them into our
projects for fast use.


Frank, please look on our improvements of viSQL.
Many things now simpler with V4RB 2.0


I think may be we can improve Structure Browser to be able manage few
database in the same time? I think for this we need array of dbs in this
window. And we must have then functions

    AddDb( db )
    RemoveDb( db) 

Then this structure browser will be very cool

Forget to say:

* Vcomponents folder now long time will be stable.
    it contains only ICU libs

* Vengine will contain dll and resources folder

Now when I try to open a db (that I just created) I get an exception: 
"File %U is already open."

When I quit and rerun, when I try to open it I get an error -61.

I did, and didn't see anything there that gave me the answer. The db 
is create with:

     tempDataBase = new myDataBase
     tempDataBase.Creator = "ABCD"
     tempDatabase.StorageEncoding = "UTF8"
     tempDatabase.collationAttribute = 2

     Valentina.ThrowExceptions = false
     tempDataBase.Create(f, 1, 2 * 1024 )
     Valentina.ThrowExceptions = true
     tempDataBase.close
     tempDataBase = nil
     myDB = f



The open code is very simple:

     if myDatabase1 = nil then
       myDatabase1 = new myDatabase
     end if
    
     try
       myDatabase1.Open(myDB) //myDB is the correct folderitem
     catch vError as VException
       if vError.ErrorNumber = -39 then //handle old version error
         ...
         return
       else
         raise vError
       end if
     end try

Well, of course it is 20 times slower, but looks much much better and
logical.

Add one more test:

    fld = table1.getFieldXtra("f1").
    
    loop 
    {
       fld.getName2()
    }


I think in this case we can get much better results!
The same is true for REALbasic for example.

It is common RULE: 
    if move from loop something then loop will be faster.
    
So test and give us results.


-------------
Also why you use such names?

    getTableXtra() ?

This should be like in realbasic

    gDB.Table("T").Field("f") = 5

I've already gave you this test - see first test & result.

This is just for testing because name "getTable" already used as static
method name.
Or do you mean "Table" name?

Igor, don't you think that it is possible to make hack here?!

1) V4MD is single-thread. Always.

2) so we can prepare

    a) one Vtable object which live long time
    b) one VField object which live long time

Just assign to them I_Table* or I_Field*
And return them as result?

No, this will not works :-(
Because we cannot differ if user have made it as tmp object
Or he have store reference to this object...

------
Well, have you investigate if something can be improved in e.g. Xtra
creation?

May be we cache some pointers to interfaces?
So next time we will use cached values instead of QueryInterface() ?

Ok, this is not the main target now Igor.
Just keep in mind that later we can think here for optimization.

Aha!


Great!

So Igor, redo design of V4MD to this new approach!

Cooooooooooooooooooooooll  !!!  :-)

Simply cool!


Now we have for V4MD the 100% correct OO design!
Exactly like in REALbasic.

One moment is even better

  REALbasic 

        db.Table("T").Field("f").value = 5
    

  Director  

        db.Table("T").Field("f") = 5


Am I right ?

Exactly:
    db.Table("T").Field("f").setValue(5)
