如何獲得SQL Server中觸發

Question

更新行ID我有一個表Employee

Emp_Id Name 
    1  XYZ 
    2  ABC 

和另一個表DivisionInfo

DivisionID Division Emp_Id 
     1  mmm   1 
     2  nnnn   1 
     3  oooo   1 

我需要寫一個觸發器回滾Employee表的更新，如果Emp_Id存在於DivisionInfo表中。在這種情況下Emp_Id = 1。

如何獲取SQL觸發器中正在更新的行的行ID？

這是我的觸發代碼：

ALTER TRIGGER [dbo].[EmployeeTrigger] 
ON [dbo].[Employee] 
FOR UPDATE 
AS 
    IF((SELECT COUNT([DivisionID ]) 
     FROM [DivisionInfo] AS D 
     INNER JOIN Employee AS E ON D.[Emp_Id] = E.Emp_Id 
     WHERE D.[Emp_Id] = E.Emp_Id) > 0) 
    BEGIN 
     RAISERROR ('Testing', 10, 1); 
     ROLLBACK TRANSACTION 
     RETURN 
    END 

這總是真的

試試這個：

ALTER TRIGGER [dbo].[EmployeeTrigger] 
ON [dbo].[Employee] 
FOR UPDATE 
AS 
IF((
    SELECT COUNT([DivisionID ]) 
    FROM [DivisionInfo] D 
    JOIN INSERTED I ON I.[Emp_Id] = D.[Emp_Id])>0) 
BEGIN 
     RAISERROR ('Testing', 10, 1); 
    ROLLBACK TRANSACTION 
    RETURN 
END
