Index fragmentation Report

I had to prepare the list of tables having more than 60% fragmentation. I wrote this query to get those information. The below query will give the list of all the fragmented tables in a particular database having more than 60% fragmentation. This will work for SQL 2005 and beyond.

Index Fragmentation in SQL Server 2005

Index fragmentation is a phenomenon where the index contents are scattered. Normally the contents are in contiguous fashion which helps in fast retrieval of the underlying data. When the indexes are fragmented the data access becomes time consuming because of the scattered data that needs to be searched and read.
