Differences between Valentina 1 and 2

Hi all!
I am sitting here since a few days to make the move from Valentina 1 to 2.
First of all I must say that the first steps were very easy. After looking
at the Wiki page for Valentina SQL (is it anywhere in downloadable form
available?) I must also say that the features are great!
But now on to my problem with one select that worked with Valentina 1 but
not with 2.
I have three tables:
A:
Name (Varchar)
Number(Long)
B:
PtrA (ObjectPtr)
PtrC (ObjectPtr)
C:
Stat1 (Boolean)
Stat2 (Boolean)
Between A and B there is a 1:m and between B and C there is a m:1 relation.
Sure there are more fields, but for this select I don't need more.
This is the old select:
Select Name,
sum(Number),
sum(Stat1),
sum(Stat2),
count(Stat2),
Number
from A,
B,
C
where A.RecID *= B.PtrA and
B.PtrC *= C.RecID
group by Number
order by Number
I tried many things but nothing worked. It seems that Boolean Values can no
longer be added (I wanted to know how many records have Stat1 and Stat2 set
to TRUE). I tried to use "sum(IF(Stat1, 1, 0))" but that always returns 1.
I tried to use "sum(case Stat1 when True then 1 when False then 0 end)",
but this also doesn't work.
Also the outer join seems not to work. I tried an simpler outer join:
Select Name,
count(Stat2)
from A,
B,
C
where A.RecID *= B.PtrA and
B.PtrC *= C.RecID
where Stat2 = True
group by Number
order by Number
but I only get one record where I expected two records.
Can someone help me?
Best Regards,
Carsten
