If the row already exists in both the tables for the same user_id, you will not do an insert.
You will do an update.

For e.g. update tbl1 set tbl1.username = tbl2.username, tbl1.password = tbl2.password where tbl1.user_id = tbl2.user_id

Hi Walker,

Here is the query you can try

SQL

IF EXISTS
  (SELECT username,password
   FROM tb_1)
BEGIN
UPDATE tbl_1
SET tbl_1.username = tbl_2.username,
    tbl_1.password = tbl_2.password
WHERE tbl_1.user_id = tbl_2.user_id 
END
 ELSE
  BEGIN
   INSERT INTO tbl_1 (username,password)
   SELECT username,
         password
   FROM tbl_2 WHERE user_id=user_id
  END

Hope this helps you a bit.

Regards,
RK
