We are planning hardware purchases (more is better). One of our databases is 131 gigs in size and has 45 gigs of 'space available'. I'm not a very experienced SQL Server person, but this seems like quite a bit of 'space available'
1) Is there a way to regulate the amount of 'space available'?
2) are there any rules of thumb for how 'space available' there should be?
Appreciate any feedback or help.

Against my better judgement, we are using fixed allocations of tempdb on some of our servers. This is to deal with specific limitations of our applicaitons and hardware configuration that I'm not allowed to discuss in much detail.
The problem that I have is that the present plan is to configure the data file at around 18 Gb and the log file at around 2 Gb. This seems just plain wrong to me, but I haven't been able to find a formal recommendation that gives any relative sizing. I would expect to have about twice as much log as data space, especially for tempdb.
Does anyone know of a formal citation (preferably from Microsoft) that discusses this?

Hi,
I have encountered a query which takes lots of temp tablespace and it fails later.
Initially the temp tablespace was 28GB, we made it to 56 GB but still it fails.
There is just this single process that is running on database.
I tried putting index on the table in query ,but no help.
Can suggest a solution to get size of temp space required or reduce its usage?
I'm trying to determine how much space some tables use (SQL2000), and I found 2 suggestions posted earlier, but can't get them to work for me.
The first was
"Right click on the DB in Enterprise Manager, select view then taskpad."
When I try that, I get some of the tables displayed with the info I want, but I can't see them all and can't scroll down beyond the first 22 tables in the database.
The second suggestion:
exec sp_msforeachtable @command1="print '?'",@command2="sp_spaceused '?'"
It says "command copleted successfully, but where does the output to this go ?? Is there something other than "print" I should use ?
The grid pane is empty.
Hi
I am using DTS to transfer tables from Oracle 9i to SQL Server 2000 sitting in a shared environment and managed to migrate
a lot of tables without glitch..
When I was migration a table <XYZ> from Oracle to SQL Server..The table was created in the SQL Server whilst the DTS threw an error that read when it was copying data and 0 rows were copied with the error message being
"Cannot create a row of size 8387 which is greater than the allowed maximum of 8060"
Incidentally the have a table in the Oracle DB that has 152 Rows of Data with 94 Columns..
Does any change needs do be done on the Admin side of the SQL Server to resolve this problem and faciliate effective transfer of data from the DB's?
Thanks in Advance

How to find rowcount and size(space used) for all tables in a db? Can any one give me the script please?
Thanks,
We can know easily a database disk size, but can we konw a table in SQL 2005 database possess size? and more, how can I know the records in SQL 2005 Table possess size space?
View 8 Replies View RelatedHi,
I was running out of space and thus deleted some rows from a table. To my surprise the db size increased. I then shrunk it to bring it back to what it was earlier.
When i deleted some 5000 rows, some space must have been released. Where did the space go and why did the db size increase after deleting the records?
I thght it might be log files..but db is set to Simple Recovery which does not utilize a Log File.
Any reasons?
What is the easiest way to calculate the space (size in bytes) used by a BLOB column that is already stored in a particular row?
Thanks.
While i execute dbcc sqlperf(logspace); I get following values.
Database NameLog Size (MB)Log Space Used (%)
master 16.17969 13.30275
tempdb 7.429688 61.7245
model 0.7421875 45.78947
msdb 5.554688 25.87904

BANKDB 23438.87 48.20037
WSMIRSDB 109.7422 4.839111
For database BANKDB , Log Space used(%) is 48.83% and Log size is about 23438.87 where as my database size of BANKDB is 60 GB. FULL database and Log back is done every day night one time. My database is performing slow now.
Do we need to take log backup frequently like once a 1 hour so that Log space used will be less. Same query is taking more time to execute than before in same database is it because of log file has increased.
I do index organize and rebuild once a week and stats apply nightly.
Is it correct once log space size is increasing more than 10%. Do we need to take log backup?
I executed the below query and getting the capacity values only for master database.All other DB shows NULL values for spaceused. I'm actually looking for a query to get all the capacity information other than using temp table and the procedures. Is there any way using SQL query ONLY.
select
db.[dbid] as 'DB ID',
db.[name] as 'Database Name',
af.[name] as 'Logical Name',
convert(decimal(12,2),round(size/128.000,2)) as FileSizeMB,Â
convert(decimal(12,2),round(fileproperty(db.name,'SpaceUsed')/128.000,2)) as SpaceUsedMB
from sys.sysdatabases db
inner join sys.sysaltfiles af
on db.dbid = af.dbid
Below is the output
DB ID Database Name

I am using sql server 2008 r2 on my end. I have created a database named testDB. I have a lot of tables with some log tables in this. some tables have contain lack of records in log table.
So my purpose is that I want to fix the table size of those tables(log tables) and want to move records in other database table placed on another location. So my database has no problem.
is there any way to make such above steps which I want for my database?
Is there already built any such functionality in sql server?

I am generating a Report from Sql Data Source in Sql Server 2005 and viewing the Report in Report viewer control of Visual Studio 2005.
The data in the Data Source contains string with multiple spaces (for example €œ Test String €œ) but when they get rendered in Report viewer control, multiple spaces gets converted to single space €? Test String €œ.
I tried following solutions
1) Replacing spaces with €œ €?
2) Inserting <pre> tag before the string and </pre> tag after the string (Also tried <Pre> instead of <pre>)
But in all the cases result is same. The Report Viewer control is showing €œ €? instead of space and €œ<Pre>€? tag instead of preserving spaces.
Please provide me a solution so that spaces can be preserved in Report Viewer.

Hi.. I was doing a good maintenance on my DB and my trans log LDF keep growing until 30GB but my DB data file MDF is only 2GB. I found the two following method to reduce my log size.
Method 1: I used veritas to backup log file with truncate
Method 2: I used the shrink database option in Enterprises manager to shrink it (file chosen=log , use default option)
After doing that, I found my LDF log file is still about the same size=27GB but when I see clearly, from the shrink database windows, the log spaced used reduced to only 100MB, the allocation log space is still 27GB. Why? How to make the LDF smaller to be the around the same size as the space used 100MB?
This is driving me bananas. Can't find any info on this anywhere....SQL 2000 seems to replace double space with a single space when I seta varchar field to " " (2spaces), it only stores " " (1space). Whyon earth would microsoft do this? If I save 2 spaces - I WANT TO SEE2 SPACES!!!!Can anyone help? Is this a database setting? Is this due to usingvarchar?Any help appreciated.Colin Hale
View 2 Replies View RelatedHello,
Somebody know how to reduce the space allocated for the transaction log space for my SQL_DB ?
3700 MB allocated but only 100 MB used and 3600 MB are free !
Transaction log properties :
Automatically grow file are filled
file growth by percent = 5%
maximum file size - restrict filegrowth = 3700 MB (we can't reduce it !)
Thank you for your precious help !

I installed sql 2005 a while back. Then I recently found out my file system was fat32 (I don't understand why the hardware people did this...) and I had to convert to NTFS. Naturally the sql service no longer worked so I uninstalled inorder to reinstall now I can't reinstall it I keep getting this message
native_error=5039, msg=[Microsoft][SQL Native Client][SQL Server]MODIFY FILE failed. Specified size is less than current size.
I'll try to post the full log in a new post.
I'm sorry to be ignorant on this point. It seems trivial, but what's the difference between @@ and @ when using variables in T-SQL? I have a developer that always uses @@ for local variables and @ for reference variables (meaning variables declared as parameters for a stored procedure or function).
Is that purely stylistic? Is it a holdover from some previous version? Or is it a legitimate best practice that I've not seen before?
My google-shui is weak today; I found nothing when searching.

Hi folks,Can anyone enlighten me here? I'm trying to use a SPROC which, when supplied with an int, looks up the table and returns certain columns from it.

Using C#, SQL Server 2005, ASP.NET 2, in a web app, I've tried removing the size from parameters of type NCHAR, NVARCHAR, and VARCHAR. I'd rather just send a string and let the size of the parameter in the SP truncate any extra chars if need be. I began getting the error below, and eventually realized it happened only with output parameters, as in the code snippet below.String[3]: the Size property has an invalid size of 0. par = new SqlParameter("@BusinessEntity", SqlDbType.NVarChar); par.Direction = ParameterDirection.Output; cmd.Parameters.Add(par); cmd.ExecuteNonQuery();What's the logic behind this? Is there any way around it other than either finding out what the size should be, or assigning a size larger than would ever be needed? ThanksMike Thomas

I have two tables :
tableA
a_id (int)
value (varchar 255)
tableB
id (int)
a_id (int)
b_id (int)
c_id (int)
d_id (int)
Both these tables contain considerable amounts of rows, but over time tableA will end up containing orphaned values (i.e. the a_id is not used in tableB) and this problem cannot be rectified by setting, for example, cascade deletes.
To fix this problem I decided to write a simple stored procedure to purge all values in tableA where its a_id is not used in tableB :
DELETE FROM tableA WHERE a_id NOT IN (SELECT a_id FROM tableB)
Now although the following document relates to postgres :
http://archives.postgresql.org/pgsql-sql/2003-12/msg00174.php
I was interested to find out if I should be wary of using NOT IN in my query.
