使用 SQL Server 2005 创建检查插入是否不存在的触发器。获取记录参数时遇到问题，代码如下：

CREATE TRIGGER t_MFShiftTypeOperation ON [CAST$MFShiftTypeOperation]
    FOR INSERT, UPDATE AS

IF @@ROWCOUNT=1 开始

IF EXISTS (SELECT * FROM inserted AS I
           JOIN CAST$MFShiftTypeOperation AS STO
           ON ((I.ShiftTypeCode = STO.ShiftTypeCode AND 
                I.PackCode = STO.PackCode) OR
                I.RegisterAppCode = STO.RegisterAppCode))
BEGIN

    DECLARE @Bad_PackCode AS EmpUserCode_t
    SET @Bad_PackCode = SELECT TOP(1) PackCode FROM inserted --there is error

    ROLLBACK TRAN
    PRINT  'Оperation with '+ @Bad_PackCode +' already exist'
END

结尾

当我尝试执行代码时，它会抛出错误消息：

 Msg 156, Level 15, State 1, Procedure t_MFShiftTypeOperation, Line 16
Incorrect syntax near the keyword 'SELECT'.

有人可以解释错误在哪里，或提出更好的解决方案。

更改此行：

SET @Bad_PackCode = SELECT TOP(1) PackCode FROM inserted --there is error

对此：

SELECT TOP(1) @Bad_PackCode=PackCode FROM inserted
