oops, typo there

the insert should be "left join" not just "left"

insert tableA
select * from tableB t1
left join TableA t2 on t1.code = t2.code
where t2.code is null

             CREATE PROCEDURE updateinsert
as
BEGIN TRANSACTION
BEGIN TRY

update a
set 	a.fname = b.fname,
	a.lname = b.fname
from tableA a
inner join table b on a.code = b.code

insert tableA
select * from tableB t1
left join TableA t2 on t1.code = t2.code
where t2.code is null
 
 COMMIT
END TRY
BEGIN CATCH
  ROLLBACK
END CATCH
