getting Index after INSERT INTO

[Andrew Sinning]

Thank you Ruslan.

One point of clarification:

Does every table have a RecID?

And this value is automatically incremented each time a new record is
added?

And this is always a unique value?  Eg, if I make 100 records and then
delete the last 50, the next new record will have RecID 101, not 51,
correct?

Thanks.

No such feature in 1.x

RecID can often be used instead.

What you ask about here?

After INSERT INTO there is no way to get this.
We need also add something as LAST_INSERT_ID

But if you will use Vcursor and built it as

    SELECT RecID, other fields
    FROM T
    WHERE RecID = 0

Then you do

    cursor.SetBlank()

    cursor.field("a") = 5
    ...

    cursor.AddRecord()


Now RecID field contains RecID of just added record.
So you can get it using

    cursor.GetValue( "RecID" )
