Need to find the amount of fragmentation in all your indexes in all databases for a given instance of SQL Server 2005 or later? You can use the undocumented/unsupported sp_MSforeachdb to loop through all the databases. For more information on fragmentation see my previous blog http://blogs.msdn.com/cindygross/archive/2009/11/20/sql-server-and-fragmentation.aspx.

— find fragmentation on all indexes in all databases on this instances
— to find fragmentation on just one db comment out the exec master… line and the last quote
— you must use the db_id() rather than NULL as the first parameter of the DMV or it will try to do a join across all dbs
SELECT @@SERVERNAME, @@VERSION, GETDATE() as BatchStartTime

DECLARE @starttime datetime, @endtime datetime

a.index_id, b.name as IndexName,
