Hi all, I have the followin query:
SELECT g.id
from onp_group g
where g.groupname IN
(SELECT ug.groupname from onp_user_group ug WHERE ug.username =
'andreak')
UNION (SELECT child_id
FROM onp_group_children
WHERE group_id IN
(SELECT g.id from onp_group g
where g.groupname IN (SELECT ug.groupname from onp_user_group ug WHERE
ug.username = 'andreak')));Any ideas on how I can simplyfy this query so that I only need to provide ug.username='andreak' once? I would much rather prefer a query which doesn't involve UNION or SUB-SELECTS. Here are the table-definitions: CREATE TABLE onp_group( id integer PRIMARY KEY REFERENCES onp_entity(id) on delete cascade, p_id integer REFERENCES onp_group(id) on delete cascade, groupname varchar NOT NULL unique ); CREATE TABLE onp_group_children( group_id integer NOT NULL REFERENCES onp_group(id), child_id integer NOT NULL REFERENCES onp_group(id), UNIQUE(group_id, child_id) ); CREATE TABLE onp_user_group( groupname varchar not null REFERENCES onp_group(groupname) ON DELETE CASCADE ON UPDATE CASCADE, username varchar not null REFERENCES onp_user(username) ON DELETE CASCADE ON UPDATE CASCADE, primary key(groupname, username) ); -- Andreas Joseph Krogh <[EMAIL PROTECTED]> Senior Software Developer / Manager gpg public_key: http://dev.officenet.no/~andreak/public_key.asc ------------------------+---------------------------------------------+ OfficeNet AS | The most difficult thing in the world is to | Hoffsveien 17 | know how to do a thing and to watch | PO.
