Hi, I have a problem when I create a function that returns a rowtype. I can't access the individual fields of that rowtype from another function if I put the results in a row type variable. I'm inserting many records into a table (let's say, insert_table). This table has a trigger on it since I need to perform some operations on each row I insert. These operations need to have default information that's stored in another table (let's say, default_values). To avoid this query getting called for every row (ie. inserting 1,000,000 records into this insert_table), I'd like to create a function that returns a rowtype result from this default_table then declare it immutable so it will only get executed once and then store the result. For example: defaults stored in: default_values CREATE OR REPLACE FUNCTION get_default_values() RETURNS default_values AS $BODY$ DECLARE ret_record default_values; BEGIN SELECT * INTO ret_record FROM default_values; RETURN ret_record; END; $BODY$ LANGUAGE 'plpgsql' IMMUTABLE STRICT; now on the trigger to the insert table we have a function that get's called before every insert. CREATE OR REPLACE FUNCTION insert_table_fn() RETURNS "trigger" AS $BODY$ DECLARE defaults default_values; BEGIN SELECT get_default_values() INTO defaults; NEW.f1 = defaults.f1; NEW.f2 = defaults.f2; NEW.f3 = defaults.f3; RETURN NEW; END; $BODY$ LANGUAGE 'plpgsql' VOLATILE; When I run this it says that there's a type mismatch and gives me the whole rowtype back ERROR: invalid input syntax for integer: "(val1, val2, val3, val4)" SQL state: 22P02 Now if I go NEW.f1 = SELECT (get_default_values()).f1 this works. But then I have a write this function out in full every time I want to get one of it's fields. ie NEW.f1 = SELECT (get_default_values()).f1; NEW.f2 = SELECT (get_default_values()).f2; NEW.f3 = SELECT (get_default_values()).f3; Why can't I declare a rowtype variable, put the result in and then grab the individual field types from that variable.
