use 'INSERT INTO table1 ... SELECT ... ' stmt in your pgplsql. EXECUTE command is the way to execute a dynamic query in your function, read developer guide PL section of docs.

Then a trigger inserts a new record into table2 using max() to get the new id from table1 (the trigger fires after insert on table1), then the procedure updates table2. In order to update table2, I need to get the max(id) so I can do: update table2 set .... where id = user_id Thanks very much. And I'm grateful for ideas about a better strategy. cheers, jd _________________________________________________________________ MSN 8 helps eliminate e-mail viruses.
