我想這兩個觸發單觸發結合起來。如何做到這一點

Question

觸發1：

CREATE TRIGGER [dbo].[INSERT_IM_ServiceRequest_Hx] ON [dbo].[IM_ServiceRequest] AFTER INSERT 
AS 

BEGIN 

INSERT INTO IM_ServiceRequest_Hx 
SELECT * FROM INSERTED 


PRINT 'AFTER INSERT Trigger fired.' 
END 

觸發2：

CREATE TRIGGER [dbo].[UPDATE_IM_ServiceRequest] ON [dbo].[IM_ServiceRequest] FOR UPDATE 
AS 

BEGIN 

INSERT INTO IM_ServiceRequest_Hx 

SELECT * FROM DELETED 

PRINT 'FOR UPDATE Trigger fired.' 
END 

Answer 1

你可以通過指定用逗號分隔的多個動作將它們結合起來在CREATE TRIGGER聲明中。然後，使用適當的條件過濾器來決定如何更新審計表，像這樣：

CREATE TRIGGER [dbo].[INSERT_UPDATE_IM_ServiceRequest_Hx] ON [dbo].[IM_ServiceRequest] FOR INSERT, UPDATE 
AS 

BEGIN 

IF EXISTS (SELECT * FROM INSERTED) AND NOT EXISTS (SELECT * FROM DELETED) 
    BEGIN 
    INSERT INTO IM_ServiceRequest_Hx 
    SELECT * FROM INSERTED 

    PRINT 'AFTER INSERT Trigger fired.' 
    END 


IF EXISTS (SELECT * FROM INSERTED) AND EXISTS (SELECT * FROM DELETED) 
    BEGIN 
    INSERT INTO IM_ServiceRequest_Hx 
    SELECT * FROM DELETED 

    PRINT 'FOR UPDATE Trigger fired.' 
    END 

END
