Change the sort order to sort by say Table name and then Index name.
use <mydatabase> go selecto.name as 'Table' ,i.name as 'Index' ,i.rowcnt as 'Est Rows' ,u.user_seeks as 'Seeks' ,u.user_scans as 'Scans' ,u.user_lookups as 'Lookups' fromsys.dm_db_index_usage_stats as u inner joinsys.sysobjects as o on u.object_id = o.id and o.xtype = 'U' inner joinsys.sysindexes as i on u.index_id = i.indid and o.id = i.id whereu.user_scans > 0 andi.rowcnt >= 1000 order byu.user_scans desc go

SQL Server 2000 has indexed views, which can greatly improve database performance. However there are a number of restrictions on building the view, including the restriction against outer joins. So how can this work? New author Jean Charles Bulinckx brings us a technique that can help you get around this restriction.

There is nothing spectacular about using indexes per say. However, on many occasions I have come across a variety of SQL coders that never consider validating that the index they think they are using is efficient or even being used at all. We can all put indexes on the columns that we think will be required to satisfy individual queries, but how do we know if they will ever be used. You see, if the underlying table data is constructed, contains, or is ordered in a particular way, our indexes may never be used. One of the factors around the use of an index is its clustering factor and this is what this article is about.
