Thank you so much...it help me lot....Big thankful to all the members....
Thanks,
I'm glad to hear it helped too. It got me to thinking that this is sort of a common problem and what kinds of business cases need the support of this kind of query.
Too bad you're not using SQL 2012. The LEAD function there is your ticket to the fastest possible solution.
My thought question: Have you ever been told that your query runs too fast?
My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
