List objects per filegroup

http://www.tsql.ca/Resources/Articles/Listobjectsperfilegroup/tabid/607/Default.aspx

The following script lists link between database objects and filegroups. You can also use this script to identify filegroup with no objects associated

SQL2000:
==========

IF OBJECT_ID('tempdb.dbo.#FileGroup') IS NOT NULL

DROP TABLE #FileGroup



IF OBJECT_ID('tempdb.dbo.#ObjectFileGroup') IS NOT NULL

DROP TABLE #ObjectFileGroup



CREATE TABLE #FileGroup (

FileGroup sysname

)

CREATE TABLE #ObjectFileGroup (

ObjectName sysname,

ObjectType varchar(20),

FileGroupID int,

FileGroup sysname

)



SET NOCOUNT ON



DECLARE @TableName sysname

DECLARE @id int



DECLARE cur_Tables CURSOR FAST_FORWARD FOR

SELECT TableName = [name], id FROM dbo.sysobjects WHERE type = 'U'

OPEN cur_Tables

FETCH NEXT FROM cur_Tables INTO @TableName, @id

WHILE @@FETCH_STATUS = 0

BEGIN

TRUNCATE TABLE #FileGroup

INSERT #FileGroup (FileGroup)

EXEC sp_objectfilegroup @id

INSERT #ObjectFileGroup (ObjectName, ObjectType, FileGroupID, FileGroup)

SELECT @TableName, 'TABLE', FILEGROUP_ID(FileGroup), FileGroup

FROM #FileGroup

FETCH NEXT FROM cur_Tables INTO @TableName, @id

END



CLOSE cur_Tables

DEALLOCATE cur_Tables



INSERT #ObjectFileGroup (ObjectName, ObjectType, FileGroupID, FileGroup)

SELECT OBJECT_NAME(id) + ' * ' +[name], 'INDEX', groupid, FILEGROUP_NAME(groupid) FROM dbo.sysindexes

WHERE FILEGROUP_NAME(groupid) IS NOT NULL

AND OBJECT_NAME(id) NOT LIKE 'sys%'

AND [name] NOT LIKE '_WA_Sys%'

AND [name] NOT LIKE 'Statistic_%'



SELECT FileGroupName = FILEGROUP_NAME(sf.groupid),/*ofg.FileGroup, */ofg.ObjectName, ofg.ObjectType, FileName = sf.filename, FileSize = sf.[size] / 128

FROM #ObjectFileGroup ofg

RIGHT JOIN dbo.sysfiles sf

ON ofg.FileGroupID = sf.groupid

ORDER BY FileGroup, ObjectName



SQL 2005 (very simplified):
===========================

SELECT

fg.data_space_id, fg.name,

ObjectName = OBJECT_NAME(p.object_id), p.index_id

,df.name, df.physical_name, [Size] = df.size*8/1024

FROM sys.filegroups fg

LEFT JOIN sys.database_files df

ON fg.data_space_id = df.data_space_id

LEFT JOIN sys.partitions p

ON fg.data_space_id = p.partition_number

WHERE (p.object_id>4096 or p.object_id IS NULL)
