If you want default value, then don't provide null as value. insert into tab1 (other, columns) values (1,2) - will put default value in text1. Since you did provide/force value of null, default isn't used. If you want to list the column, then provide "value" of DEFAULT. like: insert into tab1(text1) values (DEFAULT); But, if you want to "insert NULL value, and have NULL get automagically converted to something else" - trigger is your only sane option. Defaults are used *only* in case of "no value for column was provided". Best regards, depesz
