我有这个问题:
SELECT EquipmentNumber, EquipmentType, P.AreaCode AS Location, EquipDsc FROM MajorEquipment ME
INNER JOIN PlantAreaCodes P ON ME.PACId = P.PACId WHERE
(@EquipNumber IS NULL OR EquipmentNumber LIKE @EquipNumber)
AND ((SELECT PACId FROM PlantAreaCodes WHERE AreaCode = @Location) IS NULL OR PACId = (SELECT PACId FROM PlantAreaCodes WHERE AreaCode = @Location))
AND (@EquipType IS NULL OR EquipmentType LIKE @EquipType)
AND (@Comments IS NULL OR EquipDsc LIKE @Comments);
我收到错误" Column' PACId'在where子句中含糊不清。"
我之前尝试过此查询,其他数据并没有问题。发生了什么事?
