SQL和存储过程中的多个语句

我正在使用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：在我的存储过程中是否可能有多个查询？ 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“如果存在”部分。如何以正确的方式更改存储过程？

只需将它们放在开始和结束之间即可

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

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

@Sjemmie：这就是拥有存储过程的意义所在。您可以使用条件、进行计算、进行多个插入、删除、更新，以及您想要的任何内容。：）
