I have a field a field "GENERATED ALWAYS AS IDENTITY", after INSERT a record on the table, the IDENTITY field gets assigned to internal sequence number for the table properly.
During the same session, I'd like to recover the last IDENTITY generated during the same session, how do I do it?
I'm using ILE RPG, i5 V7R1 for the INSERT.
The reason I'd like to recover the last IDENTITY field, is because I have two tables, Header and Detail, first, I insert the record into the header table, next thing, I'll insert the record into a detail table, but referencing the header id table.
It is possible that the same program will be called multiple times at once, that is why I want to retrieve the last ID from the last insert in the session.

Re: Recover last IDENTITY after an INSERT in DB2 for i.2012-04-06T16:45:09ZThis is the accepted answer. This is the accepted answer.The scalar function Identity_Val_Local will return the last identity inserted within the same unit of work:
Exec SQL Insert into MyFile
Exec SQL Set :MyVar = Identity_Val_Local();

I also found that a quick way to test it within STRSQL after the INSERT is:
SELECT IDENTITY_VAL_LOCAL() FROM SYSIBM/SYSDUMMY1
SELECT max(IDENTITY_VAL_LOCAL()) FROM TBL_BATCHPROCESSLOGHEADER

SELECT order_id FROM FINAL TABLE (
INSERT INTO orders VALUES(DEFAULT,'11/03/2007',50,'JM12'));
