Question

这是我的代码：

CREATE TRIGGER trg_Booking
ON Bookings
FOR INSERT, UPDATE

DECLARE @bef AS varchar(25)

SELECT @bef = Role
FROM Inserted, booksys.dbo.Employees
WHERE Inserted.EmployeeNo = Employees.EmployeeNo

IF NOT (@bef = 'Foreman')

BEGIN 
    RAISERROR ('Only a Foreman can do that!',16,1)
    ROLLBACK TRANSACTION
END

尝试执行并创建触发器时，我不断收到错误消息; “Msg 156，Level 15，State 1，Procedure trg_booking，Line 5 关键字'DECLARE'附近的语法不正确。“

另外，似乎SQL Server无法识别对象“已插入”？

我正在使用SQL Server 2014和Management Studio。

Answer 1

As

之后您遗失了FOR INSERT, UPDATE

如果trigger内有多个语句，请始终使用Begin and END

CREATE TRIGGER booksys.dbo.trg_Booking
ON booksys.dbo.Bookings
FOR INSERT, UPDATE
as
Begin

IF Not exists ( SELECT 1 
FROM Inserted Inner Join booksys.dbo.Employees
on Inserted.EmployeeNo = Employees.EmployeeNo
where Role='Foreman')

BEGIN 
    RAISERROR ('Only a Foreman can do that!',16,1)
    ROLLBACK TRANSACTION
END
END

创造触发; DECLARE附近的语法不正确
