View fragmentation percentage of the indexes on a table in SQL Server

Hi Geeks,

Today I am sharing SQL query often required during performance tuning/Optimization phase of the project.The query makes use of system DMV’s provided by SQL server.Open new query window in SQL Server and fire the below query against the respective database.Just pass in the name of the table and the database for which you want to view the fragmentation.

SELECT i.name AS IndexName
, ROUND(s.avg_fragmentation_in_percent,2) AS [Fragmentation %]
FROM sys.dm_db_index_physical_stats(DB_ID(‘parisdev’),
OBJECT_ID(‘currency’), NULL, NULL, NULL) s
INNER JOIN sys.indexes i ON s.[object_id] = i.[object_id]
AND s.index_id = i.index_id
