Hello,

I have a table with 2 columns which I have a non clustered index on it in the form of column a asc , column b asc .

I ran the below 2 quires against this table and found that only query 1 utilizes index seek while the 2 query is using index scan.

This have forced me to create a second index in the form of column b asc , column a asc to get index seek for both queries

query 1: select column a from table x where column b = x

query 2: select column b from table x where column a = x

So my question here could I use 1 index to cater for both queries?

Regards,
Go
