Need information about

Hi All,

I am trying to tune a query.

Basically I joinning two table A,B on columns Col1. both having different Indexes

Example: select * from Table1 A

inner join Table2 B

on A.Col1 = B.Col1

and A.Col2 = B.Col2

In table A Col1 is defined in Join Index and in Table B Col1 is defined as SI.

and Col2 is not defined as any Index types..

I just wanted to know how i can tune this query and created SI on Column2 for both but still facing performance issue.

Please help me guys

Thanks a lot in advance  :) ;)

Need more detail. For example:

How unique / non-unique are Col1 alone, Col2 alone, combined (Col1,Col2)?

How big is table1 vs table2?
