Thank, I like the addition and appreciate you taking the time to put this together (and posting of course). You might want to change the title to Overview Info (or metrics or stats , etc.), as initially I thought it would pull a data sample from each table.

Great script. However I would get this error on some of my databases:

Msg 15009, Level 16, State 1, Procedure sp_spaceused, Line 62

The object 'tbl_Mine' does not exist in database 'Test' or is invalid for this operation.

The problem occurs when the table has a schema other than dbo associated with it. sp_spaceused will throw the error unless you include the schema like sp_spaceused 'payroll.tbl_Mine'

I modified just one line of your code to prevent this error. Here is your code followed by my edit:

Original:

declare tblname CURSOR for select name from sysobjects where xtype='U'

Editted:

declare tblname CURSOR for select OBJECT_SCHEMA_NAME(id) + '.' + name from sysobjects where xtype='U'

Thanks again for sharing this script.

Hi, awesome script.

It does not take a schema name into a picture, and fails for all tables in a non-DBO schemas.

I had to corret it:

set nocount on

if exists(select name from tempdb..sysobjects where name='##tmp') drop table ##tmp

if exists(select name from tempdb..sysobjects where name='##tmp2') drop table ##tmp2

--first temp table can hold the grouped data

--credit to Thava for gathering index counts

SELECTt.name AS TableName, t.[object_id],

SUM ( CASE WHEN i.is_primary_key = 1 THEN 1 ELSE 0 END ) AS Primarykey,

SUM ( CASE WHEN i.[type] = 1 THEN 1 ELSE 0 END ) AS ClusteredIndex,

SUM ( CASE WHEN i.[type] = 2 THEN 1 ELSE 0 END ) AS NonClusteredIndex,

SUM ( CASE WHEN i.[type] = 0 THEN 1 ELSE 0 END ) AS HeapIndex,

COUNT ( * ) TotalNoofIndex into ##tmp2

FROM sys.tables t

LEFT OUTER JOIN sys.indexes i

ON i.[object_id] = t.[object_id]

GROUP BY

t.name, t.[object_id]

order by TableName asc

--second temp table will hold the sizes

create table ##tmp(nam varchar(50), rows int, res varchar(15),data varchar(15),ind_sze varchar(15),unsed varchar(15))

go

declare @tblname varchar(50)

declare tblname CURSOR for

SELECT c.name+'.'+a.name table_name

FROM sys.objects a WITH (NOLOCK)

join sys.dm_db_partition_stats b WITH (NOLOCK)

on a.object_id = b.object_id

join sys.schemas c WITH (NOLOCK)

on a.schema_id = c.schema_id

WHERE a.type='u' AND b.index_id < 2

GROUP BY a.name , c.name

open tblname

Fetch next from tblname into @tblname

WHILE @@FETCH_STATUS = 0

BEGIN

insert into ##tmp

exec sp_spaceused @tblname

FETCH NEXT FROM tblname INTO @tblname

END

CLOSE tblname

deallocate tblname

go

update ##tmp set

res = round((cast(REPLACE(res,' KB','') as real) / 1024),-1), --convert to MB

data = round((cast(REPLACE(data,' KB','') as real) / 1024),-1),

ind_sze = round((cast(REPLACE(ind_sze,' KB','') as real) / 1024),-1),

unsed = round((cast(REPLACE(unsed,' KB','') as real) / 1024),-1)

select nam Table_Name,rows Total_Rows,res Total_Size_MB,data Data_size_MB,ind_sze Index_Size_MB,unsed Unused_Space,##tmp2.TotalNoofIndex as [Number of Indexes],##tmp2.ClusteredIndex as [NumClustered], ##tmp2.NonClusteredIndex as [NumNonClustered], ##tmp2.HeapIndex as [NumHeap], ##tmp2.Primarykey as [Has Primary Key]

from ##tmp

join ##tmp2 on ##tmp.nam = ##tmp2.TableName

order by cast(res as real) desc

--order by rows desc

drop table ##tmp

drop table ##tmp2

The script uses a fully qualified table nama as <schema>.<table>

It still is not perfect beacuese it is not showing a fully qualyfied table name, but works in 2005 and 2008

I ran into two errors on my largest database. Both were easy to remedy.

The first was simply that I had some object names in excess of your 50 character limit. I changed the two varchar parameters from 50 to 60 and eliminated the error.

The second was a collation conflict in the join. I modified the join as follows:

join ##tmp2 on ##tmp.nam COLLATE Latin1_General_CI_AS = ##tmp2.TableName

Great script. Thanks for posting!
