    SQL: field matching error

    Hello everyone,

    error correlating fields

    The following queue has the error message as its title:
    (I hope this isn’t too long ;> )

    SELECT a.SemID, b.RoomID, c.DaySeq, c.PeriodID – –
    FROM Sem Room a set, b, c Schedule;
    WHERE b.SemID = a.SemID;
    and b.SemID = c.SemID
    and c.Open implies .T. ;
    and c.LowPrior=.F. ;
    and DOES NOT EXIST;
    (SELECT * FROM BadPeriod ;
    WHERE BadPeriod.SemID = c.SemID
    ; and BadPeriod.DaySeq= c.; dayseq
    and BadPeriod.PeriodID = c.PeriodID —
    and BadPeriod.RoomID = b.RoomID);
    ORDER AFTER 1,2,3,4

    When a problem occurs, it comes from a subquery that has an external reference to
    3 tables. If I remove one of the external links in some WHERE clause of the subquery, the query works.

    Thanks for your concern:>

    SQL:field matching error

    Try this query which contains > ALL (subquery). IN (subquery) is not usually supported in this case, and EXIST (subquery) is simply not supported when dealing with multiple correlation tables. EVERYTHING would be a discovery. This is the last different logic, but the result could be the same. I need advice to check. By the way, why is there no room ID in the calendar if the room ID is in the wrong period? And what Sam brings to it.
    Solutions

    another will create a temporary schedule containing your own room id in the first request; which many would like you to refer to c.roomid in the subquery instead of .roomid.

    Hi everyone,

    error correlating fields

    The next queue generates my error message asHead:
    (I hope it’s not too long ;> )
    SELECT a.SemID, b. RoomID, c.DaySeq, c.PeriodID;
    C week a, room b, time c;
    WHERE b.SemID = a.SemID;
    and b.SemID means c.SemID;
    C et.Open = .T. —
    C et.LowPrior = .F. ;
    and DOES NOT EXIST;
    * (SELECT FROM BadPeriod
    WHERE BadPeriod.SemID = c.SemID ;
    and BadPeriod.DaySeq= c.DaySeq ;
    and BadPeriod.PeriodID = c.PeriodID ;
    and BadPeriod and .RoomID = b.RoomID);
    ORDER IN 1,2,3,4

    The problem seems to be related to a subquery that has an external reference to two tables. If I remove one of the external links in the WHERE clause of the subquery, the query will probably work.

    Thanks for the shock:>
