I think I am very close with the following CTE, but do not understand how to bring it into the main SELECT query:
WITH myself AS (
SELECT uid
FROM words_social
WHERE social = in_social
AND sid = in_sid
LIMIT 1
)
SELECT
CASE WHEN c.uid = myself.uid THEN 1 ELSE 0 END,
c.msg
FROM words_chat c
JOIN words_games g USING (gid)
JOIN words_users opponent ON (opponent.uid IN (g.player1, g.player2) AND opponent.uid <> myself.uid)
WHERE c.gid = in_gid
-- always show myself my own chat messages
AND c.uid = myself.uid
-- otherwise only show messages by not muted opponents
OR NOT opponent.muted
ORDER BY c.CREATED ASC;
SELECT uid
FROM words_social
WHERE social = in_social
AND sid = in_sid
LIMIT 1
)
SELECT
CASE WHEN c.uid = myself.uid THEN 1 ELSE 0 END,
c.msg
FROM words_chat c
JOIN words_games g USING (gid)
JOIN words_users opponent ON (opponent.uid IN (g.player1, g.player2) AND opponent.uid <> myself.uid)
WHERE c.gid = in_gid
-- always show myself my own chat messages
AND c.uid = myself.uid
-- otherwise only show messages by not muted opponents
OR NOT opponent.muted
ORDER BY c.CREATED ASC;
The error message is:
ERROR: missing FROM-clause entry for table "myself"
LINE 64: ...uid IN (g.player1, g.player2) AND opponent.uid <> myself.uid...
^
LINE 64: ...uid IN (g.player1, g.player2) AND opponent.uid <> myself.uid...
