Just change it to "delete from times_producao". Also, if consider doing a "vacuum full" or "cluster" after the batch job to clear up the free space (not in a large transaction). That will still take a table lock but it may be a small enough downtime to be worth the speed increase the rest of the day. -- greg ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
