In this post, I am sharing one T-SQL script to find average percentage of index fragmentation in SQL Server.
When we are not getting the desired performance of the index, we should check the average percentage of Index Fragmentation.
The non – clustered index data is stored into different pages and there are 100% chance of fragmentation.
I have prepared one script to find index fragmentation and after that we should execute INDEX REBUILD or INDEX REORGANIZE on highly fragmented indexes for defragmentation process.
SELECT object_name(ips.object_id) AS TableName
,i.name AS IndexName
,ips.index_type_desc AS IndexType
FROM sys.dm_db_index_physical_stats (DB_ID(),NULL, NULL, NULL ,NULL) AS ips
INNER JOIN sys.indexes AS i ON ips.OBJECT_ID = i.OBJECT_ID
AND ips.index_id = i.index_id
