Since you are SELECTing * from Table1, and doing a LEFT JOIN there is nothing to optimize on Table1 because you are indeed selecting ALL records from Table1. Again, now I am making an assumption that there is no filtering of any Table1 fields in the WHERE clause.

There is filtering in the SELECT in question, but I was trying to establish if the JOIN itself would be affected by the additional index.
