It's probably complaining that the *resultset* has two columns with the same name. Consider: CREATE VIEW test AS SELECT * FROM table, table WHERE table.a = table.b; Basically, the output of the view will have all the columnnames listed twice. You'll need to rename them to make it work... Hope this helps, -- Martijn van Oosterhout <[email protected]> http://svana.org/kleptog/ > Patent. n. Genius is 5% inspiration and 95% perspiration.
