How to write update query to update two tables with SQL Data Source?

Question

Is it possible to update two tables using SQL Data Source and ASP.NET Grid View? I have the following SQL Query for the Select statement.

SELECT 
   tbl_user

Yes, it's possible. Here is how to do it in a safe way:

CREATE PROCEDURE UpdateUser (@ID int, @Pass varchar(15), @Email varchar(75)) AS

BEGIN TRANSACTION

    UPDATE tbl_user_login SET Pass = @Pass WHERE ID = @ID

    IF @@ERROR <> 0
    BEGIN
        ROLLBACK
        RETURN
    END

    UPDATE tbl_user_profile SET Email1 = @Email WHERE ID = @ID

    IF @@ERROR <> 0
    BEGIN
        ROLLBACK
        RETURN
    END

COMMIT

In this way you don't need to be worried in case there is some error raised by any of the updates. Which means: If any of them will fail, the whole operation will be canceled and you will not have inconsistent data in your DB.

The basic DELETE statement is: DELETE FROM WHERE
