Question

我正在研究SQL Server 2005，我有一个非常简单的存储过程：

create PROCEDURE [dbo].[tblTabel_Insert] 
@ID int,
@Code nvarchar(50) = null
AS
    SET NOCOUNT ON;

  IF  EXISTS (SELECT ID, code FROM tblTabel WHERE ID = @ID and code = @Code) 
    UPDATE tblTabel SET ID = @ID,code = @Code WHERE ID = @ID

ELSE
BEGIN

INSERT INTO tblTabel (ID,code) VALUES ( @ID ,@Code);
END

我的问题是：在我的存储过程中有多个查询是否可行？我想添加行

UPDATE tblTabelB SET ID = @ID,code = @Code WHERE ID = @ID
UPDATE tblTabelC SET ID = @ID,code = @Code WHERE ID = @ID

在我的if exists部分。如何以正确的方式更改存储过程？

Answer 1

IF  EXISTS (SELECT ID, code FROM tblTabel WHERE ID = @ID and code = @Code) 
BEGIN
    UPDATE tblTabel SET ID = @ID,code = @Code WHERE ID = @ID
    UPDATE tblTabelB SET ID = @ID,code = @Code WHERE ID = @ID
    UPDATE tblTabelC SET ID = @ID,code = @Code WHERE ID = @ID
END

Answer 2

将它们放在BEGIN和END之间

IF  EXISTS (SELECT ID, code FROM tblTabel WHERE ID = @ID and code = @Code) 
BEGIN
    UPDATE tblTabel SET ID = @ID,code = @Code WHERE ID = @ID
    UPDATE tblTabelB SET ID = @ID,code = @Code WHERE ID = @ID
    UPDATE tblTabelC SET ID = @ID,code = @Code WHERE ID = @ID    
END   
ELSE
BEGIN

INSERT INTO tblTabel (ID,code) VALUES ( @ID ,@Code);
END

SQL和存储过程中的多个语句
