Sorry I'm still confused. as I said in my earlier e-mail I've built the
program using the -t option for ecpg. AUTOCOMMIT is set to on, however I
still get an error when opening a declared cursor:

"DECLARE CURSOR can only be used in transaction blocks".

If I stick a EXEC SQL BEGIN WORK before declaring the cursor it seems to
work ok, but I thought the -t option saves me from having to do that each
