hi,
I used sp_spaceused 'owner.tablename' and it shows index size as 24kb whereas there is no index on this table.
I thought may be it's not showing the right statistics so I update the statistics but it is still showing the same .
what is happening?
I am using SQl 2k/Win2k.
TIA.
When I run sp_spaceused I will get something like:
database_name . database_size . unallocated space
------------------ ----------------- ------------------
. . . DBA . . . . . . . 2.50 MB . . . . . 0.07 MB
reserved . . . . . . data . . . . . . . index_size . . . . unused
------------------ ------------------ ------------------ ------------------
1720 KB . . . . . . . 888 KB . . . . . . 648 KB . . . . . .184 KB
Is there any way to load this info into a Table?
I'm having trouble because there are (2) result sets returned.
I am using the sp_spaceused system stored procedure to identify tables in my database that are large. I have two questions. Can anyone help me sort this list. I assume this is returned in clustered order, but I want to order the list by rows. Also, when I run this sp_spaceused stored proc, on some of my tables I get a negative value returned under the 'index_size' and 'unused' columns in my result set. How can this be.

unused space.
I do NOT want the log size calculated into the database size or
the space unused.
Thank you
on some of our sql 6.5 databases the space available is shown as 0MB. I realise that I must run sp_spaceused to get an accurate result, but the results I then get are slightly confusing. All I want to know is the space left in both the database and the log - can I get a reading for both?. Sometimes the unused space is shown as a negative number. Can anyone advise since books online is fairly unspecific.
(the total script that i run incidentaly is:
exec sp_spaceused
go
DBCC checktable (sysindexes)
go
DBCC checktable (syslogs)
go
exec sp_spaceused @updateusage=true
go)
Thanks
Can someone please explain the outputs below of the sp_spaceused stored procedure.

View 1 Replies View RelatedWhat does sp_spaceused show nonzero sizes for data, reserved and index size when the table is empty?
It also does this on 6.5.
I have ran sp_spaceused (SQL 6.5 SP4) on my database (4000MB Data, 500 Log) and received the following output for "Reserved" : 4412390 KB. Note that this is more than 4000MB. I checked and made sure my data and log were truly separated...
Just to make sure, I added 2000MB more data space. Sp_spaceused now returned the following for reserved: 3493220 KB.
I am wondering why the allocation dropped, while no user activity was taking place during the process of growing the database....sp_spaceused reported data size first at 2725532, then at 1806314. Any ideas? A bug? Did the database fill up and begin using log pages...?
Any help is GREATLY appreciated...
Thanks!

Hi,
I ran sp_spaceused against a DB table, and got -160K in the field "unused". If anybody can explain what this negative number means?
We have a problem with performance. It's extremly slow. The table contains 600,000 records. Even simple select * from <table> (table scan) takes 6 minutes. This is SQL Server2000.
Any help is appreciated.
I can't remember if I posted this already or not:
CREATE PROCEDURE sp_space @sortbyrows bit=0 AS
SET NOCOUNT ON
select cast(object_name(id) as varchar(50)) AS name, sum(CASE WHEN indid<2 THEN rows END) AS rows,
sum(reserved)*8 AS reserved, sum(dpages)*8 AS data, sum(used-dpages)*8 AS index_size, sum(reserved-used)*8 AS unused
from sysindexes with (nolock) where indid in(0,1,255) and id>100
GROUP BY id with rollup
ORDER BY CASE WHEN @sortbyrows=1 THEN sum(CASE WHEN indid<2 THEN rows END) ELSE sum(reserved)*8 END desc
Usage:
EXEC sp_space --show stats sorted by reserved space size
EXEC sp_space 1 --show stats sorted by row count
It basically displays the results of sp_spaceused, but broken out by each table, and it rolls it up to a grand total. Naturally, for the most accurate results you should run DBCC UPDATEUSAGE before running this sproc.
I am looking for a way to programatically determine the size of the data contained in a table, much like the sp_spaceused proc in SQL Server.
Thanks.

Table1
2553136
294424 KB
293176 KB
1072 KB
176 KB
When I run sp_spaceused on a table called Table1, I get numbers as shown above.
I have a clustered Index on a datetime column AND that is the only index on the table.
So according to my calculations Index Size should be 2553136 (No. Of Rows) X (8 (DataType of DateTime) + 4 (Uniquifier) )
So the number I should be seeing in the Index Size column = 2553136 * 12 = 30637 KB, why am I only seeing 1072 KB ?
Where am I going wrong in my calculations.
To be more specific -- how do I calculate the Size Occupied by Indexes on a Particular Table ??
Thanks
What does the following SQL code mean?
EXEC sp_msforeachtable 'sp_spaceused ''?'''
I executed sp_spaceused on the db ang got following results
database_name:myDB
database_size: 1017.75 MB
unallocated space :104.13 MB
reserved : 309752 KB
data : 306832 KB
index_size : 1936 KB
unused : 984 KB
If we add reserved,data,index_size and unused up , we will get around 600MB.But the database has size of 1G. Could anyone tell me why?
Hello,
I started to write a stored procedure to insert into a temp table from sp_spaceused but couldn't get the format right. I did a search in the swynk archive and saw that some people have solved this but I couldn't see any example code. Does anyone have scripts they've written to gather db size info using sp_spaceused or some other mechanism?
Thanks in advance,
Dan
Hello:
I have gotten the following information from sp_spaceused:

I unfortunately since this is for a test database that I have put the data and log on the same device.
My questions are:
1) Why do I have negative numbers?
2) Should I be concerned about this?
3) for a live database can I drop the log and put the log on another device? What do I need to do?
4) has anybody seen this before?
5)what can I use to get accurate numbers?
THanks. Any information will be greatly appreciated.

How is it that the value returned by sp_spaceused is larger than the actual database size and unallocated space be negative? For example sp_spaceused retruns the following for one of our databases.
database_size = 52022.31 MB
unallocated space = -16462.47 MB
reserved = 69559520 KB
data = 68007688 KB
index_size = 1463456 KB
unused = 88376 KB
That does not make much sense to me how the reserved size and even data size can be larger than the database_size.
This database was 85 gigs yesterday but we were running extremely short on disk space so I was forced to do a shrink. I did update stats for the database as well.
Thanks much.
hi,
sp_spaceused return 2 set of results. How do i store this result into a table?
Thanks
On a production database, there is a 2GB database, when I runsp_spaceused it indicates a very high quanity of unused space. Thedatabase has been shrunk & free space sent to the OS. Why is thisvalue so high, what can I do to reclaim the space?database_name database_size unallocated space------------------------------------------------------------------------------DB_00001 2004.13 MB 49.64 MBreserved data index_size unused------------------ ------------------ --------------------------------1531248 KB 412720 KB 165168 KB 953360 KB
View 5 Replies View RelatedHi,
I am struggling to understand how to run the sp_spaceused sproc for all tables in a database.
I know how to use it for one table but how would I replicate it automatically for each table in a given database?
Regards,
Ian.
When comparing the data space available (Edit Database dialog within Enterprise Manager) to sp_spaceused, I occasionally generate numbers that have discrepancies.
Example
Enterprise Manager shows data space available = 160.43 MB
sp_spaceused (Unallocated space = 397 MB) less log space (200 MB) = 197 MB
Even after I run (sp_spaceused @updateusage = 'true'), the problem is not resolved. Are there any known issues with space being calculated incorrectly from within Enterprise Manager? Should I not rely on Enterprise Manager and stick with sp_spaceused to find out database usage? Are there any other methods which will resolve this problem? Any help would be appreciated.
Thanks,
Karl
I have a large table that I recently purged a year of data from.However, the table size in sp_spaceused hasn't decreased as much as Iwould expect. (there are no text or large object columns on thistable, BTW) Running sp_spaceused on the table shows the following.rows reserved data index size unusedTABLE_NAME23470880 67790808 KB 18116312 KB 3211616 KB 46462880 KBI ran a dbcc indexdefrag on all indexes on the table last night,including the clustered index, and I'm still seeing pretty much thesame amount of space reported as unused.The one thing that I haven't done yet is to run the sp_spaceused onthis table with the @updateusage flag set to true as I need to do thisafterhours to reduce contention. I will attempt this tonight andreport on the results.Here's DBCC SHOWCONTIG OUTPUT for the table:DBCC SHOWCONTIG scanning 'TABLE_NAME' table...Table: 'TABLE_NAME' (917578307); index ID: 1, database ID: 7TABLE level scan performed.- Pages Scanned................................: 2264447- Extents Scanned..............................: 285484- Extent Switches..............................: 287092- Avg.

This is not really a possibilityfor me due to the size of the table and the availability expectationsof my customers. Is there anything that I forgot to check? Do youthink that it's just a matter of incorrect statistics in sp_spaceused?Thanks in advance:Matt
View 4 Replies View RelatedCould some one help me to explain what does it means when I ran sp_spaceused on the database it reported ex. -15430kb for unused. Does this mean that the index ran out off space. Do I need to increase space for the database. I will try to run the dbcc check hope it will fix the problem.
Thanks.
Hi All,
When i run sp_spaceused on one of my database, PROD, it gives the following output
database_name: PROD
database_size: 4268.00 MB
unallocated space: -789.82 MB
reserved: 4654920 KB
data: 2929008 KB
index_size: 327272 KB
unused: 1398640 KB
Why is that the unallocated space is negative ?
On the drive where the datafiles resides there is enough free space . Also, the datafile and transaction are set to auto grow with unlimited file growth
FYI - the OS is Windows 2000 and the DB is SQL Server 2000 with SP3
Appreciate your time and help on this.
I want to look at the size of the current database, so I can create a newone if it gets too big (we are working around the 2gb MSDE limit for ourcustomers).I would like to do something like this:DECLARE @size INTEGERexecute BLOB0000.dbo.sp_spaceusedand make @size = the database_size column value that sp_spaceused returns.Any way to do this?Thanks.
