Documented T-sql For File Space ?
Jun 27, 2006
Hi There
I would like to write sql to check that space used by any given data file in SS2000.
sp_spaceused only returns the total space used by the DB or object in the DB, not for a specific data file.
DBCC SHOWFILESTATS does give me this information , but it is not documented in BOL, i would prefer not to use an undocumented command to ensure future use in later versions. Is DBCC SHOWFILESTATS an undocumented T-SQL command ? If so what documented t-sql command will provide me with this information ?
I could query system table's and work this out , but as mentioned this may not not work in future versions of SS.
Thanx

The following test seems to contradict documented behavior....
1) Running SQL Server 2005 Express with Shared Memory (SM) and TCP enabled connect via ADO.
2) Connect with "localhost", it connects using SM.
3) Disable SM and restart the Server Service.
4) Connect with "localhost", it connects using TCP.
5) Enable SM and restart the Server Service.
6) Connect with "localhost", it still connects using TCP!!
To restore a SM connection, the only way that I have figure out is...
7) Disable TCP and restart the Server Service.
8) Connect with "localhost", it connects using SM.
And then restoring TCP does not change the connection
9) Enable TCP and restart the Server Service.
10) Connect with "localhost", it still connects using SM.
If you run steps 1 - 6 but skip #4, step #6 will connect with SM. So one concludes that the TCP connection is somehow "sticky".
Any ideas on how to force a shared memory connection in step #6?

I've production sql server 7 sp3 on windows NT. I had a 8GB data file ofwhich 5GB were used and 3GB were unused. I wanted to take back the unused3GB.So I did the following with EM GUI:1. I tried to "truncate fre space from end of the file". Didn't truncatethe file. I believe there was no empty space at the end of the file.2. Next I chose the option to "shrink file to 5GB". And to my horror thedata file instead of taking just 5GB took the empty spaces also and the sizeof the used data file went to 8GB.Any idea what's going on?TIA,SP

One of the primary parts of my job is working with the SQL database of our Enterprise ERP software. One of my primary responsibilities is writing reports based on it's data and since it is not well documented and this is one of my biggest challenges. To top it all off, it's hard to even use their reports to learn the links between tables as the reports run completely in Visual Foxpro.
Is there reasonably priced software that will analyze the database for me and make it easier for me to figure out the relationships between certain tables and such?
TIA,
Dave

Hello all, according to the documentation for the DeviceInfo parameter of the ReportingService.Render method the Xml string fragment of PageHeight and PageWidth for the Image Device Information Settings should and I quote.
The page height, in inches, to set for the report. You must include an integer or decimal value followed by "in" (for example, 11in). This value overrides the report's original settings.
Emphasis mine. Page width is similar. However when I change that value to what is desired for the IMAGE format it has no effect whatsoever no matter what value I place in there.
Indeed the size that is rendered is more related to the current display resolution setting rather than the PageHeight/PageWidth values passed in. In otherwords if my laptop has a higher resolution of 1920x1200 and the server that I deploy this WS to has a lower resolution of 1280x1024, the image rendered on the higher resolution display fits on to an 8.5x11.0 in page with room to spare but on the lower resolution display it is clipped because it does not fit the page.
Is there something that I am doing wrong or is this indeed a bug?
Thank you,
John

I have been working on an application which require as much percision as we can get. We have defined all numeric values as (38,16) however when ever we divide a number by the result of a built in function it truncate the percision to 5 decimal place this cause us to have a small but enoying loss in the numbers being caculated we need a minimuim of 8 decimal places or better is there a work around or solution for this problem in sql server 2005. The more percision the better.
example: select tna/(select sum(tna) from taum) from taum where fund_id = 2345
the result is always 5 decimal places even though fund_id tna = 2569698.23 and sum(tna) =98745612325879.36 which should equal .00000002602341683313994 instead the result = .00000

Hello,
I am trying to run SSIS project which is failing on one of the dataflow. This dataflow should create in Destination approximately 209,405,240 records. My flow is failing and the reason for it €“ size and log file.
This is the error I am getting.
An Ole db record is available. Source: €œMicrosoft SQL Native Client€? Hresult 0x80004005 Description: €œThe transaction log for database €˜tempdb€™ is full. To find
out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases.
An ole DB record is available. Source: €œMicrosoft SQL Native Client€?

Create disk space by deleting unneeded files, dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for eisting files in the filegroup.€?
Please let me know what can I do about it? Should I change some properties? How do I make it work and have better performance?
Thanks.

Is there a way to know how much space is free in each transaction log file of the same database?
Example:
A database with 3, 1GB files for transaction log: A, B and C created in this sequence.
From what I have read, since SQL Server 2005 writes to a single transaction log only, I guess if the transaction log is using 2.5GB than A and B are full and B is only half full. Is this correct?
Thanks.

I am currently SQL admin since our ordinary SQL folks are at summer vacation.
Yesterday SCOM alerted that File Group is running out of space on one not so critical database "The file group "PRIMARY" for the database "loganalys" in SQL instance "MSSQLSERVER" on computer "sqlserver2" is running out of space".
I logged in to the SQL server and checked the database in question. It is a very large DB with a size  of 577 GB.The storage on which the database files resides has 123 GB free space so that isn't the issue.
The database is set to autogrowth 1 MB at a time (unrestricted) so that doesn't seem to be the issue either.However, in the database properties under General, it says Space avaliable: 570 MB.
I guess that this may be the issue, that this is under some treshold for SCOM to alert on.I have looked at the other databases and they have everything between 0,25MB to 270MB space avaliable (they are all set to autogrowth 1 MB, unrestricted).
I am not sure what this means and if I have to do something about it?

Hi There
As part of monitoring i want to hourly check the data file percentage used for each database, to monitor growth and know in advance when a data file will be full.
However i do not want to write a job for ever single database , this instance may have up to 100 databases that = 100 jobs.
So i want to write a job that checks the percentage space used for all databases.
My first dilema is that i cannot loop through databases dynamically, by that i mean if i use a cursor that loops through database names, and i dynamically build sql the say 'USE @DBNAME' and execute it the cursor context stays local you do not actually change database context.
So how do i loop though databases, i have found
sp_msforeachdb, however this is undocumented in BOL.
Secondly how do i check the percentage of space used for the data file or files for a database, i could use DBCC SHOWFILESTATS, however this is also not documented in BOL.
Obviously i would rather use documented methods.
So bottom line what tsql could i use to check the percentage of file space use for all databases?
Thanx

The system I had developed is having a data flow as following:
Source received as file, .dat file
For better performance I€™m doing little transformation between .dat file to SSIS Raw file then from Raw files doing Type2 and Type3 mappings to adhere the business rules and loading the data to destination tables.
The .dat file I receive (there are many file some where around 25 file) is dumped in a folder as €œsource€? and the Raw file are in other folder as €œSSIS files€?.
My concern is the source folder size is 6GB and the same files converted in SSIS raw files format present in SSIS FILE folder and the size of this folder is 10GB.
Why is that so? Where as there€™s no extra data and the transformations between source and SISS files are like substring for the different date format and data type conversion.
Any ideas, your help in this would be appreciated.
Thank you

Hello all
as indicated by my stupid question, I am very new to sql. our vrsion is 2000 and I'm talking about in enterprise manager, the database that was created is not showing up in the list of db. Although I can see the file in explorer.
The problem I€™m having is when I try to attach the database €œmailarchive3Q2007_data.mdf€? it is also looking for the log file €œmailarchive3Q2007_log.ldf€? . The log file was removed by someone else off our system. I have a backup of the file but it is too large to restore now (160 gig) when the system was first set up the recovery model was not set to simple so the log just grew till it filled up our drive. I no longer have the drive space necessary to restore the log file and shrink it. So what do I do now? I need some kind of €œmailarchive3Q2007_log.ldf€? file to attach the database in enterprise manager.
Hope sombody can help.
thanks
Mike

We've got an alert setup on our production database to warn us when the log file(s) exceeds 7 gigs. The Alert is triggering:
"The SQL Server performance counter 'Log File(s) Size (KB)' (instance 'Lexus') of object 'SQLServer:Databases' is now above the threshold of 7000000.00 (the current value is 7057656.00)."
However, according to the file system, the database properties screen files, and properties tabs, the log files combined are at under 5 gigs so this alert should not be going off.
The scary part is, when going to right-click on the database, choosing "tasks" and going to "Shrink > Files", the "Free Space" shows negative numbers for the first log file:
Log 1
Currently Allocated space: 118.69 MB
Available Free Space: -5323.24 MB (-4485%)
Log 2
Currently Allocated space: 4853.13 MB
Available Free Space: 411.20 MB (7%)
Has anybody ever run into this? Should I be worried that there is a bigger issue at hand?
Thanks!

Hi all
My Transactional log size increased to 39GB, it is in full recovery mode,
To regain the space, i have done the following
BACKUP LOG DB_NAME WITH TRUNCATE_ONLY
DBCC SHRINK_FILE (LOG_FILE_NAME,500)
But not able to regain the space in the hard disk.
No Transactional backups to truncate the log file were setup.
Can you please tell me why the space was released and what should i do further to clean up the sapce

This script can be used to shrink a database file in small increments until it reaches a target free space size.
It will loop to execute the DBCC SHRINKFILE command to shrink the database file by the desired increment until it reaches the target free space.
It is often better to shrink database files in small increments so that it can make continuous, incremental progress, instead of trying to shrink by a large amount in one command. This makes it easier to shrink a database that must be shrunk by a large amount, and makes it easier to interrupt without losing all progress.

Recently maintenance was done removing some tables from the original filegroup in one drive of our SQL Server 2012 Standard Edition 64bits to another created on a separate physical drive. I was expecting the full amount of data moved to the secondary filegroup to show up as unused on the primary filegroup but that doesn't seem to be the case. Do I have to do anything after the move to release that space, not to disk, but to the database as unused?

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?
