创建插入触发器

发布于 2024-10-30 22:14:02 字数 523 浏览 3 评论 0原文

如何在 SQL Server 中编写一个触发器，当将某些数据插入另一个表时，它可以帮助我将值插入到一个表中？而且我还想使用第二个表中插入的数据来插入第一个表。

有表 A 和表 B，

当将一行插入表 B(TBLP1ISLEM) 时，

我想将此插入中的多个单元格插入

表 A(TBLP1DOVIZKURU) 中。

表B，插入

触发器帮助=>表A，插入

谢谢。

代码

CREATE TRIGGER [dbo].[Deneme] 
   ON  [dbo].[TBLP1ISLEM] 
   FOR INSERT
AS 
IF(SELECT ID FROM inserted)>0
BEGIN
    SET NOCOUNT ON;
    INSERT INTO TBLP1DOVIZKURU(ISLEM_ID,DOVIZBIRIM,KUR) 
    SELECT ID, PARABIRIMI, KUR FROM inserted


END

How can I write a trigger in SQL Server that will help me to insert values into a table when some data is inserted into another table? And I also want to use the inserted data in the second table to insert the first table.

There is Table A and Table B,

when a row is inserted into Table B(TBLP1ISLEM)

I want to insert several cells from this insertion,

into Table A(TBLP1DOVIZKURU).

Table B, inserted

Trigger help => Table A, inserted

Thank you.

code

CREATE TRIGGER [dbo].[Deneme] 
   ON  [dbo].[TBLP1ISLEM] 
   FOR INSERT
AS 
IF(SELECT ID FROM inserted)>0
BEGIN
    SET NOCOUNT ON;
    INSERT INTO TBLP1DOVIZKURU(ISLEM_ID,DOVIZBIRIM,KUR) 
    SELECT ID, PARABIRIMI, KUR FROM inserted


END

在表 B 上添加触发器以进行插入。它将允许您捕获插入的数据并用它做任何您想做的事情。你可以使用插入的数据，你可以查询另一个表......等等......

CREATE TRIGGER trigger_Insert_TableB
ON TableB
FOR INSERT
AS
Begin
    Select * FROM Inserted //This will give you the inserted data
End

Add a trigger on Table B for insert. It will allow you to capture the inserted data and do whatever you want with it. You can use the inserted data, you can query another table ... etc ...

CREATE TRIGGER trigger_Insert_TableB
ON TableB
FOR INSERT
AS
Begin
    Select * FROM Inserted //This will give you the inserted data
End

CREATE TRIGGER your_trigger_name
ON  [TableB]
FOR INSERT
AS 
BEGIN

INSERT INTO TableA (tA_field1,tA_field2,tA_other_fields)  SELECT tB_field1,tB_field2,tB_other_fields FROM Inserted

END

CREATE TRIGGER your_trigger_name
ON  [TableB]
FOR INSERT
AS 
BEGIN

INSERT INTO TableA (tA_field1,tA_field2,tA_other_fields)  SELECT tB_field1,tB_field2,tB_other_fields FROM Inserted

END
