Syntax Description

YES: returns the value of the last inserted identity value.

Details

You can use this option instead of issuing a separate SELECT statement after an INSERT statement. If FETCH_IDENTITY=YES and the INSERT that is executed is a single-row INSERT, the engine calls the DB/2 identity_val_local() function and places the results into the SYSDB2_LAST_IDENTITY macro variable. Because the DB2 engine default is multirow inserts, you must set INSERTBUFF=1 to force a single-row INSERT.
