In SQL server, I am trying to insert values from one table to another by using the below query:
delete from tblTable1 insert into tblTable1 select * from tb
They don't have the same structure... I can guarantee they are different
I know you've already created it... There is already an object named ‘tbltable1’ in the database
What you may want is this (which also fixes your other issue):
Drop table tblTable1 select * into tblTable1 from tblTable1_Link
