XML size cost to a database

Posted By:      Posted Date: August 28, 2010    Points: 0   Category :Sql Server
I am in the process of integrating a procedure that imports data into an xml format. The question I have what is the cost on disk versus just importing each colunm. Say I have 10 columns of data, how much more space does an xml column take than just 10 individual columns with the same data. I have searched everywhere and I can not find a definite answer that addresses this question. Any help is greaty appreciated.

database size limit about SQL Server 2005 Express

I know that there is a size limit (4 GB) for SQL Server 2005 Express, but I am not quite sure if the limit is applied for only ONE database data file or for ALL the database data, suppose I have two databases DB1 and DB2, so which of the following statement is correct? A. The size limit for DB1 is 4GB, and the size limit for DB2 is also 4GB, so if DB1 is 3G and DB2 is 3.5G,that will be OK. B. The total size for both DB1 and DB2 can not be larger than 4GB, which means if DB1 is 3G, then DB2 can not be large than 1G.

Maintenance of Database of Size 620 GB on Production


Hi Guys

I have a serious problem here. I have a Audit database of 620 GB with just two tables in it.  This database has 2 years worth of data. Both these tables have around 900 million rows in each of them. Each of the tables get around total of 2-3 million rows everyday. This database is on SQL Server 2005 Enterprise Edition. Machine has just 870 GB of total Space Drive. We are left with just 180 GB of free space. Now I have a requirement to make it smaller and keep just 1 year of data in live database. I have a option of purging the data every week. But I believe it wont be easy to purge such a large of rows if we do purging just on weekends.

Can you please suggest me some ways to attain this goal of 1 year of data in database ? Also if you could you suggest for future how can i maintain the database. I am not able to do any maintenance task(like re-indexing,update stats  etc..) on it.


Please help me to find some solution for it.

Restore database from system dbs and log file when .mdf file size set to 0KB after Windows Update ?


This can't be right. Friday I tried to install some Windows updates including ‘Security Update for …Windows Server 2008 for x64-based Systems (KB2416473)’ on both my host Server 2008 box and on a VM instance of Server 2008 running on the same physical box. An important SQL Server 2008 instance lives on that VM.


The above mentioned update failed on both the host and the VM, but a system shutdown and reboot were required for both OS’s anyway. When SQL Server started up again on the VM, the *.MDF file size for 2 (out of maybe 15 total) databases had been reduced to 0KB. Additionally, 1 of accompanying *.LDF files was now also 0KB in size, while the other *.LDF file was probably its normal size of 2.9GB. All the other databases and log files, including Master.mdf, seem to be okay.


I’m new to SQL Server and have a couple of questions of cours

Share point database and site collection size, and restrictions and workflow


Sharepoint site collections


More Detail



We had a 3rd party into to develop the share-point service, This is really a very difficult situation not the solution but the documents that are stored and the way it was retrieved.


The real thing is that we receive an item it is booked into SAP and then we send an automated xml to set up a local site this site will then have details from the SAP system fed by ABAP. After the site is created, and then we add documents files and .jpg. These documents must show a detailed audit trail so that if challenged in a court of law can show who had access and who updated documents. 


SO the problem is 


1 Site Collection that is 170gig and the design means that we have 1600 sites and these contain images that are stored in the single site collection. How do we remove the full documents and images and replace with links rather than the doc, img. 


2. We have around 8 business units the problem is that they can share information acros

"Initial Size" of a database ...

Since these days almost all applications require some kind of db repository, we are also in the same boat. We have an email archiving system that has atleast 6 SQL Server DB repositories (sigh). The problem is that the scripts that were run to create these databases, assumed an initial size. For instance, one such DB file's initial size is 1110 MB of which most of it is empty. We are trying to reclaim the free space but to no avail. My question is this, when you right click a db in Management Studio and click on the files tab, does the ""Initial Size (MB)" column indicate the size used to define the db when it was created? Can I reduce the DB size to less than this defined size? APpreciate any feedback.

script to check the database size



I work with Microsoft SQL Server Workgroup Edition 2008 and I would like to know if there is a script to check the database size.

I need something like ‘give databasename’ and return the database size.
Can I do this via a vbscript?

Background info:
Different departments one SQL Server.
Every department has one or more databases on the SQL Server.
Department managers are billed per GB in use.
Department managers require a script to check the database size without using Microsoft SQL Server Management Studio or any other console. Just a shortcut on their desktop.

Let me know if you need more information.
Thank you,

size of schedule database backup bigger than the manual backup


i've created a job to schedule backup everyday, here the script used:


NAME = N'ON_KEY_4-Full Database Backup', SKIP, NOREWIND, NOUNLOAD,  STATS = 10

this back up is too big about 120g but when i do manual backup the database is only 3g. i think the DB is not being overwritten but back up on top of each one.

how can i make to overwrite each time the script is executes.


thanks in advance

How do you set the LocalConnectionString Max Database Size property on the RDA object in C++?


How do you set the LocalConnectionString Max Database Size property on the RDA object in C++?

We have an C++ application running under PPC 2003. The SQL Server Compact edition 3.5 service pack 2 is installed.

We have successfully created a local database using the DBPROP_SSCE_MAX_DATABASE_SIZE property and set the size to 386mb.

The local database can be written locally to up to the Max Database Size.

When we perform a Pull operation with the RDA object the Pull fails when we set the Max Database Size property on the RDA LocalConectionString.

When we perform a Pull operation with the RDA object the Pull succeeds when we set only the Data Source property. But we can only Pull up to 128mb (the default size).



Problem with database size and the 4GB limitation


I'm using the express edition, and it has the 4GB limitation, but I am a little bit confused because I have a 3,6 GB database backup and I want to restore it in the database, but when I try to restore it,  the terminal shows me an error that saids "the database is bigger than the 4096MB" limit.

The question is, Why does this happens if the database is smaller than the limit?


Thank you in advance,
