    try using an "include" option on your index. this will allow you to store the actual data at the leaf level and keep from having sql go back to the data to pull it (bookmark lookup) . I would run it with "SET STATISTICS XML ON" and look at what it says in the xml are missing indexes. It should recommend and index with the "include" parm.

    Mike,
    Tried SET STATISTICS XML ON and that returned an error. And how to include the include option in index do we have to specify that while creating an index or in the select statement. Your suggestions were useful but dint help to sort my issue. thanks.

    Cheers

    How often the database optimization tasks such as REDINEXING & UPDATE STATS are scheduled on this database?

    Unfortunate to say this. I took over the DBA just last week. And saw that they were not scheduled. I have scheduled those jobs to execute every week hence forth. I executed update stats, rebuild index and reorganize index yesterday. And now every thing is up-to-date.

    Cheers

    [<img src='/community/emoticons/emotion-1.gif' alt=':)' />] I meant to say as you are new that working environment, never under estimated your DBA experience. Anyway you are in right place to achieve what you want as a DBA.<br /><br /><b>Satya SKJ</b><br />Microsoft SQL Server MVP<br />Writer, Contributing Editor & Moderator<br /<a target="_blank" href=http://www.SQL-Server-Performance.Com>http://www.SQL-Server-Performance.Com</a><br /><center><font color="teal"><font size="1">This posting is provided AS IS with no rights for the sake of <i>knowledge sharing. <hr noshade size="1">Knowledge is of two kinds.

    Satya,

    I dint say that you under estimated my experience i just misundersttod your statement and expressed my view that i had almost 4 years of SQL DBA exp. Unfortunate till today i have been more and more infrastructure oriented DBA than a development DBA. So tuning queries takes time for me to address the right place to get it right.

    Cheers

    It is not a good practice to delete the question after getting solved
    This prevents others from learning new things

    Again edit your topic and post the question and let your "thanks" reply as new reply
