Is it possible to create a temporary table within a rule?
I get a syntax error near 'CREATE TEMPORARY TABLE' if I try to do the
following:
CREATE RULE id_insert_rule AS
ON INSERT TO id_insert
DO INSTEAD
(
CREATE TEMPORARY TABLE id_temp (
LIKE
id )
ON COMMIT DELETE ROWS;
INSERT INTO id_temp (
username,
pass_md5,
pass_sha1 )
VALUES
new.username,
encode( digest( new.password, 'md5' ), 'hex' ),
encode( digest( new.password, 'sha1' ), 'hex' );
DELETE FROM
id
USING
id_temp
WHERE
id.username = id_temp.username;
INSERT INTO
id
SELECT
*
FROM
id_temp;
);
As you can see, I'm trying to create a simple 'insert or update' rule.

No, sorry. From memory, rules only allow SELECT/INSERT/UPDATE/DELETE
plus NOTIFY (and there are restrictions on the latter).
