Hi,
Is there any way to define a SQL stored function that inserts a row in a
table and returns the serial generated?
CREATE TABLE matchmaking_session
(
session_id bigint NOT NULL DEFAULT
nextval('seq_matchmaking_session_id'),
...
);
CREATE FUNCTION create_matchmaking_sesssion(...)
RETURNS bigint
AS $$
INSERT INTO matchmaking_session(...)
VALUES (...)
RETURNING session_id;
$$ LANGUAGE SQL;

SELECT.
2008-01-10 22:08:48 EST CONTEXT: SQL function
"create_matchmaking_sesssion"
What about
$$
INSERT INTO .... ;
select currval('seq_matchmaking_session_id');
$$ language sql;
?
