Find Table Fragmentation

[cc lang=”sql”]

DECLARE @Database VARCHAR(255)
DECLARE @TableName VARCHAR(255)
DECLARE @IndexName VARCHAR(255)

SET @Database = ‘SQLServerPlanet’
SET @TableName = ‘Users’
SET @IndexName = NULL

SELECT
avg_fragmentation_in_percent
,page_count
FROM sys.dm_db_index_physical_stats
(
DB_ID(@Database)
,OBJECT_ID(@TableName)
,OBJECT_ID(@IndexName)
,NULL
,NULL
)

Or you can still do it the old fashioned way. Just substitute the name of the table or index below. It should not be in quotes.

[cc lang=”sql”][/cc]
–Just the table
DBCC SHOWCONTIG (tablename)

–Table with the index
DBCC SHOWCONTIG (tablename, indexname)

–Do not block anything (run during prod hours)
DBCC SHOWCONTIG (tablename, indexname) WITH FAST –(2005)

Modified the query for all tables (with table name) and with frag more than equal to 50 in descending order.

DECLARE @DATABASE VARCHAR(255)
DECLARE @TableName VARCHAR(255)
DECLARE @IndexName VARCHAR(255)

SET @DATABASE = DB_NAME()
SET @TableName = NULL
SET @IndexName = NULL

SELECT t.name TableName
,sp.avg_fragmentation_in_percent
,sp.page_count
FROM sys.dm_db_index_physical_stats
(
DB_ID(@DATABASE)
,OBJECT_ID(@TableName)
,OBJECT_ID(@IndexName)
,NULL
,NULL
) sp
INNER JOIN sys.tables t ON sp.object_id = t.object_id
WHERE sp.avg_fragmentation_in_percent >= 50
ORDER BY avg_fragmentation_in_percent DESC
