There is already an object named 'tbltable1' in the database
The SELECT INTO statement creates a new table of the name you provide and populates it with the results of the SELECT statement.
I think you should be using INSERT INTO since the table already exists. If your purpose is in fact to populate a temporary table, then you should provide a table name that does not already exist in the database.
See MSDN for more information on this.
If you are confident that tbltable1 is not required, you can drop the table first.
You may also want to consider using temporary tables...
Select * into ##MyTemporaryTable FROM tblTable1_Link You can then use the temporary table in this session. (Ending the session should drop the temporary table automatically, if I remember correctly. It's been a while since I've worked with SQL Server).
