SQL Check Index Fragmentation


Thanks to Ola Hallengren, here is a simple scrip to report the fragmentation level of you database’s index
One thing to note, if you don’t see any results after running this, you may have no index larger then 1000 pages, or no fragmentation at all ! Lucky you !

DECLARE @DatabaseID int
SET @DatabaseID = DB_ID()
SELECT DB_NAME(@DatabaseID) AS DatabaseName,
 schemas.[name] AS SchemaName,
 objects.[name] AS ObjectName,
 indexes.[name] AS IndexName,
 objects.type_desc AS ObjectType,
 indexes.type_desc AS IndexType,
 dm_db_index_physical_stats.partition_number AS PartitionNumber,
 dm_db_index_physical_stats.page_count AS [PageCount],
 dm_db_index_physical_stats.avg_fragmentation_in_percent AS AvgFragmentationInPercent
FROM sys.dm_db_index_physical_stats (@DatabaseID, NULL, NULL, NULL, 'LIMITED') dm_db_index_physical_stats
INNER JOIN sys.indexes indexes ON dm_db_index_physical_stats.[object_id] = indexes.[object_id] AND dm_db_index_physical_stats.index_id = indexes.index_id
INNER JOIN sys.objects objects ON indexes.[object_id] = objects.[object_id]
INNER JOIN sys.schemas schemas ON objects.[schema_id] = schemas.[schema_id]
WHERE objects.[type] IN('U','V')
AND objects.is_ms_shipped = 0
AND indexes.[type] IN(1,2,3,4)
AND indexes.is_disabled = 0
AND indexes.is_hypothetical = 0
AND dm_db_index_physical_stats.alloc_unit_type_desc = 'IN_ROW_DATA'
AND dm_db_index_physical_stats.index_level = 0
AND dm_db_index_physical_stats.page_count >= 1000
