ok. thanks. Just checking that it can't be done. I am working with some
existing code and can't use SEQUENCE and IDENTITY.

The equivalent SQL would be to declare an update-able cursor with

CURSOR <...> then commit...

Only other option would be to do a LOCK TABLE prior to the SELECT INTO and
UPDATE..

Personally, I'd consider using SQL identity or sequence columns...

Otherwise, just use your RPG as a UDF or SP.

in rpg record I/O I lock a control record, increment a control number,

update the control record. Which reliably gives me a unique value.

C** GET NEXT SID NUMBER FROM WCMAST
C inwacd CHAIN WCREC
C EVAL WCNSID += 1
C UPDATE WCREC
/free
outSid = wcnsid ;
/end-free

Can I use SQL to do the same thing?

thanks,
