You can pick which column gets the default value by omitting the appropriate field from the INSERT command. eg: CREATE TABLE test (a int default 0, b text default 'foo'); INSERT INTO test (a) VALUES (10); -- b gets default value INSERT INTO test (b) VALUES ('bar'); -- a gets default value On Mon, 2002-11-18 at 18:49, Felipe Schnack wrote: > Yes, and you're not wrong (but I don't consider it right too) > > 1- As I said, my reasons to want that are laziness :-) > Why?
