Re: Displaying chat by punished users only to themselves (db fiddle attached)

[Alexander Farber]

I think I am very close with the following CTE, but do not understand how
to bring it into the main SELECT query:

https://dbfiddle.uk/?rdbms=postgres_14&fiddle=ee264dc98b44dee75aa4523164a327b3

        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;

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...
                                                              ^
