Because I have 3 separate update and/or insert statements per do, wanted to make sure all succeed, and wasn't sure exactly how the return value would account for all possible errors. From my testing, it looks like do returns only the last statement result rows.

Now if I add a rollback before the 2nd eval:

warn $inventoryUpdate.$statement."\n"; eval{ $result=$db->do($inventoryUpdate.$statement); warn "result1=$result\n"; }; if($@){ warn "Can't update. Trying insert.\n\n$inventoryInsert$statement"; $db->rollback; eval{ $result=$db->do($inventoryInsert.$statement); warn "result1=$result\n"; }; if ($@){ warn "Aborted because $@"; $db->rollback; return 0; } } $db->commit;
It works! Apparently, the rollback resets $@, but why is the $@ message different in the 2nd eval without the rollback?
