I wanna use a function as a column default value. the problem is that I don't
know how to use a function as a default value (how to call it) and that my
function ain't working properly. so here is my function:
CREATE FUNCTION myfunction() RETURNS trigger AS '
BEGIN
select count(episode.show_name) from episode where
episode.show_name=show.show_name;
return countshow;
end;
' LANGUAGE plpgsql;
this function is a query that counts how many show_name are in the table
episode, show_name is a foreign key from table show. the result is suppose to
go in the column count_show in table show.
thanx in advance
