Varbinary (max) Release Space Used After Delete?
Nov 8, 2007
Hi,
When -all- records from a table with a varbinary(max) column are deleted (not via truncate), the table properties
still show a dataspace size from before the delete operation.
Inserting new blob records only leads in the growth of the allocated space withouth reusing the empty
already allocated space.
Runnning commands like dbcc updatusage/checkdb/cleantable/reindex or sp_spaceused @updateusage = N'TRUE'
seem to have no effect.
Does anyone know when space allocated by a varbinary col. is released?
thanks,
Derk

Hi all,
I'm running SQL 7.0. Due to large tables, the space on the SQL server was getting filled up. So i truncated some tables. Now even though the SQL dbase shows 3Gb free, the HDD shows only 150 MB free. How do i get SQL 7.0 to release the sapce back to HDD?
Thanks

Hi,
I am using SQL2005 SP1 and I have a 4Gb Tempdb (datafile) with virtually nothing in it.
I am unable to release the free space to the operating system. I have used dbcc shrinkfile...truncateonly but this has had no effect.
There is no error message and there are no open transactions, I have attempted to drop the data file by transferring to a new file but I can't because it the primary file...
Any idea would be very helpful!!
Cheers.

SQL7: After doing a full backup Enterprise
Admin still shows "Transaction log space"
in use. Isn't it that way that full backup
releases all space formerly used by
log files?

Hey guys,
I have a table which has 6 text columns (tblA).. I no longer require 1 of those text columns and want to reclaim the space that it is currently taking up..
Is the only way to BCP out all the data (except the 1 column i no longer require) drop the column and BCP the data back into the table?

We have a database with about 500 GB of free disk space on data file and the database is being set to read only mode for the fore-see-able future. We would like to release this unused disk space. We know that we could shrink the data file and then work on re-indexing to remove fragmentation.we wanted to check if some other method like backup and restore of the database could free up unused disk space in the data file. if someone was able to release unused disk space on data file by implementing a backup and restore.

Hi ,
I have a table let say TableA , which have a size of 22 GB.Due to its size i down size this table by deleting 40% rows.So ideally it should size to 15 GB but space is not released by TableA. How i can do it ? I tried shrink database, shrink data file wizards and DBCC command , Reorganize the index but all is in vain.
Any suggestion /solution?

I have scenario where I have process that loades data into SQL server 2012 database by doing some manipulation on data like sorting , aggregation, etc. Once this process is completed it's not free up the Tempdb space. If I restart the database, then it does.
is there any way (apart from shirking) to release space for Tempdb, like writing some post SQL queries to delete/ truncate the data and logs from temp db?

I have a database that I am using as an archive for emails and am storing them in varbinary(max) data types. The database works fine for inserts and retrieval but I cannot delete large sets of records ( > 30K) without it timing out. I assume this is because SQL server isn't simply releasing the handle to the blob but is instead doing a lot of work reclaiming the space.
Is there any flag I can set or approach I can use to resolve this issue?
I was considering moving the blobs into a seperate simple table and putting async triggers on the primary to delete the blobs, will this work?
Any ideas are appreciated. Besides the "store files in the file system" idea.

I am new to mssql server. There is a table on one of my databases that occupies a lot of space. And the space usage is as follows: (all values in KB)
reserved: 42329064
data: 16272288
index: 26050032
unused: 6744
This table takes up almost 80% of my database size, and the information is this table just captures the time spent by a user on the website(not very critical data)
I would like to know how to delete the entire index (which is what is occupying most space) to free up disk space. the index is a clustered index.

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?

Hello,
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 !

Hello,
I've tried searching for details on the next release date of SSRS, but can't find any. Has anyone heard anything regarding the next release? There are at least a dozen features that I really would like to have, and when searching for each, the MSFT developer typically responds with "that feature is targeted for a future release". So I'd like to know if anyone has any idea, even heard a rumor, regarding the next release timeline. Or, is there a better place to search for this information?
Thanks!
Michael

If we upgrade an instance to SP2 (CTP), can we simply apply SP2 (Release) on top of the SP2 (CTP)? Or will we need to uninstall the whole instance, re-install SQL 2005 and only then apply SP2 (Release)?
I notice in section "1.1 Overview of SQL Server 2005 SP2 Installation" of the documentation the statement:
"During installation, SQL Server 2005 SP2 Setup will list all installed components of SQL Server 2005 and allow you to select the components to upgrade, including components that have already been upgraded to SP2. For more information, see the SP2 Setup documentation."
I'm hoping that this means you can apply the release SP2 on top of a ctp SP2 with the result being full release SP2 versions. I've read the "SP2 Setup documentaiton" and it did not clarify for me.
Thanks!

P.S. - sorry for the duplicate posting... I think posting this as a reply to the announcement (as I originally did) didn't get it much attention.

Dear all,
We are working on C++ in eVC++ 3.0 environment (CE 3.0) with SQL CE 2.0.
While executing the SQL CE commands like GetData(),GetNextRows() and Seek(), 8 KB keeps increasing each time in the memory. We are releasing the accessors,columnsinfo,rowsetchange,rowset handles properly.But still the memory increases without being released.
Have we missed out anything?
Kindly help us in this regard.

We alter the database schema that our production application uses with almost every release. Is there a way to basically remove the replication and re-do it for all tables / views at one time? Then we could just "rebuild" the replication with every release. We have about 200 tables and 200 views that have many dependencies. I'm sure it could be done with scripting and the stored procedures, but I'm new at this and not sure where to start. Any ideas? Thanks!

I`ve been following the newsgroups, and the consensus had seemed to be
that 7.0 would be released around November. However, I spoke to a Microsoft
partner last week who told me that the release date would be sometime in
the second quarter of 1999. Does anyone know whether if this is true/untrue?

The former programmer wrote this stored procedure. It haven't been run for a while, so I was given the assignment to get it working. When I ran the stored procedure, it took almost 9 hours. Then I found that I can't access a few tables, so my guess it there is some issues with table locking. The stored procedure use this...
Code:
BEGIN TRAN
--blah blah
COMMIT TRAN
ERROR_HANDLER:
ROLLBACK TRAN
Obviously there seem to be a logic error in the middle of the script while running the stored procedure. So, how do I cancel the transaction and unlock the table? I'm unable to access the few tables.
Also, does rebooting the computer helped to release the transaction or table locking?
Thanks...

Hi,I am having an issue with SQL server that slows everything to a crawl,and makes almost any query impossible to complete.Here are the symptoms:I stop SQL, I start SQL. The task manager shows SQL starting up andquickly allocates 50 MB of memory. I then open SQL Manager and I canopen up the instance of SQL Server and I expand to see all of thedatabases, memory rises to about 70MB allocated. I then expand adatabase and view a list of tables. The memory allocation quicklyrockets to 860+ MB and any attempt to query they database results inhuge hang times.I have MacAfee anti-virus in place and it is constantly scanning forviruses, so I don't think it is a virus. The log files do not appearto be large. I have done everything I know to do to resolve this. Anyhelp would be much appreciated.Does anyone have any ideas?Thank you for taking the time to read this.Tod

Hi,Our DBA group is debating production release methodology. We alwaysperfect our deployment package (typically a script) against thedatabase in a Staging environment, before executing the packageagainst Production. One side argues that the safest approach is tocreate a script containing all schema changes, data changes, storedprocs, functions, etc. Run that script against Staging until it iserror-free. Then, when you run it against Production on Release Nightyou know it will also be error-free, since Staging is a copy ofProduction. However, any changes to the deployment, such as updatesto procs (and there are always a bunch in the pre-deployment period)must be manually implemented on the script.The other side wants to take advantage of the .NET environment. Wekeep all procs, views, and functions in a Release folder on VSS,execute a Get Latest Version (Recursive) from VisualStudio, and runagainst Staging/Production. Any changes to the procs areautomatically propagated from VSS to VS, and there is no manualediting of the script. You still need a script for table and datachanges. The "script everything" side of the debate feels this methodis not as reliable, especially since when views are nested, you willget compile errors and must execute the run-on several times until allthe views compile. The "script" side feels that any errors areunacceptable in a Production environment.What is the opinion out there?Thanks!
