Hey,
Thanks for the help. But no, not even by declaring a view it works.
It follows pretty much the same pattern that I just described in
response to Osvaldo Kussama's message. If you do a "naked" SELECT
on the movies table, Postgresql correctly tells the client that
the types are NOT NULL. However, if you do the same via the
function get_movies, the types are transformed into NULL.
This is some very odd behaviour...
Cheers,
C.S.
P.S. The code using the view:
SELECT movie_id, movie_name FROM movies;
=> returns a SETOF of (int4 NOT NULL, text NOT NULL)
SELECT movie_id, movie_name FROM get_movies ();
=> returns a SETOF of (int4 NULL, text NULL)
CREATE TABLE movies
(
movie_id int4 UNIQUE NOT NULL,
movie_name text NOT NULL,
PRIMARY KEY (movie_id)
);
CREATE VIEW view_get_movies AS
SELECT movie_id, movie_name FROM movies;
CREATE FUNCTION get_movies ()
RETURNS SETOF view_get_movies
LANGUAGE sql STABLE
AS
$$
SELECT movie_id, movie_name FROM movies;
$$;
