View as plain text  
This is my Trigger which doesn't seem to work; but doesn't cause a error

DROP TEMPORARY TABLE IF EXISTS tempHotelRateAvailability;

    CREATE TEMPORARY TABLE tempHotelRateAvailability(AuditTrailId
varchar(36),UserId bigint(20),ActionType
enum('INSERT','UPDATE','DELETE'),TableName varchar(36),RowKey
varchar(255),FieldName varchar(36),OldValue text,NewValue text);
    IF NEW.RoomsToSell <> OLD.RoomsToSell THEN
        INSERT INTO tempHotelRateAvailability VALUES
(UUID(),NEW.LastChangedBy,'UPDATE','HotelRateAvailability',
CONCAT(OLD.RoomID,'|',OLD.Day),'RoomsToSell',OLD.RoomsToSell,NEW.RoomsToSell);
    END IF;

    IF SELECT COUNT(*) FROM tempHotelRateAvailability > 0 THEN
INSERT INTO AuditTrail
        SELECT tempHotelRateAvailability.* FROM tempHotelRateAvailability;

    END IF;

DROP TEMPORARY TABLE tempHotelRateAvailability;

However if I use this call in the Trigger and change a value in the table
it works fine;

INSERT INTO AuditTrail
(AuditTrailId,UserId,ActionType,TableName,RowKey,FieldName,OldValue,NewValue,
LoggedOn)
 VALUES (UUID(),1,'UPDATE','HotelRateAvailability', 1,'RoomsToSell',1,2,
NOW());
