From: sqlcatz on 11 Sep 2009 05:26 Hello Tibor, I was searching for information on [sys.dm_db_index_usage_stats] and came across this thread. A table which exists in our db has 1 Clustered and 1 non-clustered index. The clustered index has: scans:0 seeks:66 lookups:3848. The non-clustered index has: scans:0 seeks:5328 lookups:0. I understand what the numbers mean for the scans & seeks - but the lookup is confusing me. Can you please point me to a URL which descibes the [sys.dm_db_index_usage_stats] and how I should interpet the above numbers. cheers sqlcatz
