I have some questions.First on which bases this sql statements decides that the index is unused and second is this command applicable on sql server 2000 too?

Hi!!!!
ReplyDeleteMicrosoft introduces the dynamic management views from SQL Server 2005.
If the index is not used by SQL Server (Dead Index) then the dynamic management view (sys.dm_db_index_usage_stats) does not have record for that index.
