Question

I’m trying to retrieve the closest adjacent rows (above and below) a record in a result set that match a certain condition.

My problem appears to be in my use of min and max here:

WHERE   ma_c.id = 2 
            AND ma_e.id > 4 
            AND ma_e.id = MIN(ma_e.id))

The error I receive is:
error : Invalid use of group function

Not quite sure what I’m doing incorrectly

    (SELECT     
        ma_c.id                 as contest_id,
        ma_c.name               as name,

—–EDIT—-
This is the relevant schema uml for the query I’m attempting to execute

    FROM    ma_contests ma_c
    JOIN    ma_users ma_u
    ON      ma_c.id = ma_u.contests_id

    JOIN    ma_entries ma_e
    ON      ma_u.id = ma_e.users_id

    WHERE   ma_c.id = 2 
            AND ma_e.id > 4 
            AND ma_e.id = (SELECT min(_ma_e.id)       
                            FROM    ma_contests _ma_c
                            JOIN    ma_users _ma_u
                            ON      _ma_c.id = _ma_u.contests_id

                            JOIN    ma_entries _ma_e
                            ON      _ma_u.id = _ma_e.users_id

                            WHERE   _ma_c.id = 2 
                                    AND _ma_e.id > 4)

and same for the next query
