Hi Maria, Try something like CREATE OR REPLACE FUNCTION myfunction() RETURNS SETOF RECORD AS $body$ DECLARE rec record; BEGIN FOR rec IN ( SELECT * FROM sometable) LOOP RETURN NEXT rec; END LOOP; RETURN; END; $body$ LANGUAGE 'plpgsql' VOLATILE; As you can see, the number and type of the output fields only depends on whatever table you query in the FOR loop. It's not magic though. It just postpones defining the number and type of the output fields until querying the function. You will have to define the output fields when querying your function, like select * from myfunction() as ("field1" integer, "field2" text, ...)

In that case I cannot predefine the table with column. If I use RETURNS SETOF then I should know the number of columns and its type?! Is there anyway to return a resultset with any number of column? Thanks for your help. -maria
