I have one table having more than 3 millions rows with following columns:
I am using 8 different queries, all thru stored procedure, to fetch data.
SITE_ID, USER_NAME, ORG_NAME and ACTION are in all queries WHERE clause.
I have created SITE_ID as non-unique clustered index and USER_NAME, ORG_NAME and ACTION as non-unique non-clustered index.
Problem is that data fetching without indexs is faster than when creating idex.
Is there any problem in index columns.
Can you please suggest me a better index plan.
I have attached the queries / column table image file.
