SQL and multiple statements in stored procedure

Question

I'm working on SQL server 2005 and I have a very simple stored procedure:

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

My question is: is it posible to have multiple queries in my stored procedure ? I want to add the lines

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

in my if exists section. How do I change my stored procedure in the correct way ?

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

Just put them between BEGIN and 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
