SQL 2005 Express And CPU/Memory Limitations.
Jul 8, 2006
SQL Express Ed is limited to one CPU, what happens if the CPU is a dual core CPU? Does SQL Express care? Does it see a dual core as a single CPU?
As for memory, stupid question, SQL Express is limited to 1 GB RAM, if I run it on a server with say 4GB of ram packed into it, will it affect SQL Express' performance? Will SQL Express even run if there is more than 1GB available? Or will SQL Express simply ignore the extra RAM with no negative consequences?
Thanks,
Andy

Hello,
I am aware that SQL Express has a memory limitation of 1GB. I am trying to determine if this 1GB memory is shared with the Report Server. In other words, if I run a query that requires 600MB of memory, and a report that pushes the Report Server to 600MB of memory, will I exceed the 1GB limit for SQL Express? Or are these two separate processes for memory limitation purposes?
If they are separate processes, are there any limitations to the Report Server as far as performance when using the Express edition of SSRS? If not, would it not make sense to push the Report Server harder than the database when running reports if SQL Express is my target platform? (e.g., do MORE work in the RS, and less in the database itself)
Thanks,
Michael

Hi all,I have recently implemented a SQL 2005 cluster using SQL 2005 Standardon Windows 2003 Enterprise edition.Both nodes have 4GB of RAM and according to the datasheet, SQL 2005Standard can support the OS maximum memory amount and Win2K3 EntEdition can support 64GB!However, in Enterprise Manager, if I go to the "Memory" tab of theinstance properties I can't increase the memory beyond 2147483647(which I assume is around 2GB).I don't have AWE enabled but am unsure as to the ramifications of this.Any advice anyone could provide would be greatly appreciated.Many thanks,Ian

Dear,
I'm building an ASP.NET application using C# language and SQL Server 2000. This application is dedicated to be hosted on a VIsta Machine.Unfortunately Vista does not supports SQL SERVER 2000 so i must migrate to the SQL SERVER 2005. Since the application is a small application, we couldn't afford buying an SQL SERVER 2005 License so i decided to use SQL SERVER 2005 Express Edition. But i would like to know exactly what are the Limitation on the Express Edition to see if it will work with my application or No. Please Can anyone refer any document that describes in details all the limitation of the Express Edition ??? Thanks a lot.

Just been reading up on this and there are a lot of limitation which one needs to consider when designing an in-memory table. I'm going to post them below in the hope that others will add to them so I can get a definitive list;
No foreign key constraints
No clustered indexes
No schema changes once the table is set in memory
No index changes once the table is set in memory
Alter Table function is not supported
Additional filegroup needs to be created in order to process in-memory tables
Varchar MAX is not supported
XML/User Defined data types are not supported
Max page length is 8060 (page overflow not supported)
Can't create indexes on NULLABLE columns

Does the aspnet_wp.exe get considered in memory limitations for SQL Express? (1GB limit) I'm asking because I run the Reporting Services on the same box (this is required with SQLE). When I run reports, it seems much of the work is in the aspnet_wp.exe process, so I'm trying to determine if running reports will get considered in the 1GB memory limit of SQLE. I know, however, that the ReportServer database and the ReportServerTempDB database WILL get included in the 1GB limit, but am trying to figure out if the aspnet_wp.exe process gets considered as well when it is running reports.
Thanks,
Michael

Hi everybody,
I know that SQL2005 Express has 1 GB memory limitation.
Well, if my server has 2 GB RAM and I have other applications (without memory constraints) how does this relate to the SQL constraints ?
Can I still run SQL2005 Express if other applications exaust only 1 GigaByte of memory ?
Thank you in advance.

Dear All,
I have 1 problem here. I developed a desktop application and I am using SQL 2005 Express as my application database.
I found that after I closed my application, the SQL 2005 Express memory resources do not release. How do I release the memory resources except of restart the SQL services?
Do you guy have any better recommendation of other database is more suitable for desktop application?

Question:
Can the SQL 2005 express edition can be installed on a machine that has more than 1 GB memory?
If so, is the SQL 2005 express edition will be using memory upto 1 GB?

Hi,
I'm hoping that some might have an answer for me after much net searching.
I have a server (200GB disk space, Dual 3.8 GHZ processors, 4GB memory) that hosts 6, very small, SharePoint sites (WSS 2.0) and SQL 2005 express handling 1 config DB and 7 content DB's.
The biggest DB at the moment is only 300 MB and the sites are not actively being used yet, they are only open to a select number of users (+ - 25 in total) who are using them as reference "areas" at the moment. Each site is running in it's own application pool as well.
I find that the sqlserv.exe process increases in memory usage and does not seem to decrease. It gets to the point of 960 MB usage and then databases cannot be used (SQL 2005 Express max memory is 1GB). SQL seems to "close" them down and site errors being received are "site is not in configuration database". When the SQL service is restarted the memory usage idles around 70 - 80 MB, the sites are 100% again but after an hour or 2 the memory usage is sitting at 560 MB again and doesn't seem to decrease.
Is there a way I can bring this memory usage down?
Any feedback would be greatly appreciated.

Hi, I was curious if anyone knew if there was a way to get around SQL Express Edition 2005's limitations to support remote connections. If I install SQL Server 2005, will there be a smooth transition between the two on my IIS 5.1 server? My database is extremely simple and only consists of a single table without any complex queries. Idealy, I would like to spend no money since I am a poor collge student doing this as a project. Suggestions?

I had a question about the CPU limitations of SQL express. It says limited to 1 CPU but what if I have multiple instaces since the application is a new service and runs in it 'sown memory space how is it limited to 1 CPU? does the service use multiple processors and the queris are binded to one?
Thanks

With the limitation of 1Gb of ram and 1 CPU for SQL Express, does that mean we cannot load it on a server with multiple CPU's and more ram, or that we can load it and it will only use 1CPU and 1Gb of ram?

I was looking around, and I found this info on SQL Server Express:The 4 GB database size limit applies only to data files and not to log
files. However, there are no limits to the number of databases that can be
attached to the server.Does this mean I can use several different databases in my website, like one separate db containing forum entries, and one with user details and related stuff?

Hi,
I am currently using the SQL Server Express edition with the intention of upgrading to the full version in the future.
I know the size limitation on the Database is 4GB - however does this include the log file as well? Nothing I read says the log file is included however if anyone can give the definitive answer I would be grateful.
Also my log file maximum is set to 2GB what issues are there with reducing this to say 500MB? I assume SQL Server automatically drops the old log data to add new data when the maximum is reached.
Thanks for your help.

I have software that uses SQL Server Express as it's database. I am only able to import so many records until it stops and fails to allow me to import anymore.
I'm very new at this but, is there some type of limitation on Table size that's preventing me from importing anymore data?
I'd really appreciate it if someone could help me,
Thanks... Bill

Is there a document/technical article/white paper, basically, some information as to what can be exported into a particular format and what cannot be.
I have a report which is fine when exporting to Excel but doesnt export to XML or CSV. All I get in XML or CSV is just a heading. I am thinking, may be its not right to export that report into XML or CSV formats.
Has this happened to anybody before? Any advise is appreciated.

I've created a database design and I'm trying to figure out if it's workable or not. I have 2 tables in particular that are sparse (20 columns, but only a few have data - about 100 bytes/row) but will grow very large - to the tune of 700 million rows.
My question is whether or not there is a problem with SQL Server 2005 having 1.5+ billion rows of data even though it will likely only take up 100 gigs or so on disk. Anyone have experience in large numbers of rows like this? We're still doing testing as far determining how slow queries will get.
Thanks,
Craig

I am looking for a doc (BOL, etc.) which enumerates things like limits on the number of columns which can be replicated, or limits on the size of the row. BOL covers this for 2000, but I can not find it in BOL 2005.
Thanks.

Hi, I'm not sure if this is where I should post this, but I'm trying to find out what the limitations of SQL Server 2005 Developer Edition (DE) are. I've gone through the Microsoft SQL Server site and they have very little information about the developer edition.Is there a connection limit for DE like 2000 did?

Hi,
Apologies for the generic subject heading but I have a client who at my suggestion has implemented a reporting solution using SSRS. However, we are now finding serious limitations with this solution, primarily regarding exporting matrix data to Excel. The major concern is that after exporting matrix data you cannot sort, filter or format properly as we cannot repeat the group data, merged cells is also another big problem.
They are now seriously looking at bringing in different technology to address these problems and I was wondering if anybody had any positive ideas, as to how I can provide a way forward and overcome our issues?
Can I easily add an add-in to the existing export options, does SQL 2008 offer any improvements, are there any 3rd party offerings out there?
Grateful for any advice.

Okay, when will SRS 2005 support Office 2007 extensions.
I find it hard to believe that a service pack has not been releaseed to support Office 2007. If there is I apologize in advance for this message.
Info: Microsoft.ReportingServices.ReportProcessing.WrapperReportRenderingException: An error occurred during rendering of the report. ---> Microsoft.ReportingServices.ReportRendering.ReportRenderingException: An error occurred during rendering of the report. ---> System.Exception: Excel Rendering Extension : Number of rows in the Excel sheet exceeded the limit of 65536 rows.

Hi,
I'm trying to learn some VB programming with the VB 2005 Express Absolute Beginner Series video tutorials (which I think is great) and have come across a problem that I can't solve.
When I follow the instructions in Lesson 9 (Databinding Data to User Interface Controls) my application will display the data from the database correctly and I can edit it (and as long as the debugger is running the data remains changed). However, the changes won't propagate back to the database. I don't get any error messages but after I edit the data, save (with the save button on the BindingNavigator toolbar), and end debugging the data in my database remains unchanged. When I use a MessageBox to show how many rows where edited/updated in the
Me.myTableTableAdapter.Update(Me.myDatabaseDataSet.myTable)
I get the correct number back. I'm sure the problem is not due to coding errors since I've also tried running the accompanying Lesson 9 project file that can be downloaded from MSDN and the problem persists.
I'm using Windows XP SP2, SQL Server 2005 Express Edition and VB 2005 Express Edition. I've tried installing SQL Server 2005 Express with a number of different settings, including default settings, but it doesn't make any difference.
Would greatly appreciate any feedback on this as I'm keen to resolve this problem so I can get on with the next tutorial lesson.
Thanks,
Ieyasu

Hi,
I have a small sized db (size doesnt goes on 50mb - currently its 15mb ) on my computer and my application uses that db.
Normall SQL Service uses 50-60 mb of system memory.
But after some heavy usage SQL 2005 express Services memory usage goes near 1GB and sometimes SQL Service stops itself.
Does SQL 2005 express stops itself when it reaches the 1GB memory limitation?
Regards,
Cem

Hi
We are developing some applications for Sunit computers (In-vehicle computers) which have limited memory . Because the applications display maps, the will consume alot of memory. Because of this, we want to restrict the amount of memory and other resources SQL Server Express uses to a minimum. I've tried setting 'max server memory', which doesn't help too much as this is only a limit on the SQL engine and not the sqlserver.exe process. What other settings and restrictions can I apply to limit memory consumption by the process?
We have considered using SQL Server Everywhere, but as it doesn't support ODBC (will there be any ODBC support?), we are not too happy about using it. As of now, we have no experience with OLE DB, and the application is MFC 6.0 so we can't take advantage of ADO.NET
Best regards

This problem only occurs after deployment, not when debugging. In the table I am having a problem with I have an ID field designated as the primary key with the identity increment set to 1 and the identity seed set to 1. There is no data in the table when deployed. I can add records to the datagridview control but when I try updating the dataset I get this error indicating that the ID field already has a value of 1 present. If I close the application and re-start it, the exception no longer occurrs when I update the dataset. I am including the code to update the tables incase something is wrong there. Any suggestions?
Private Sub UpdateMemberTable()
Me.Validate()
Me.TblMembersBindingSource.EndEdit()
Me.TblMembersTableAdapter.Update(Me.ChurchFamilyDataSet.tblMembers)
Me.TblMemberDependentsBindingSource.EndEdit()
Me.TblMemberDependentsTableAdapter.Update(Me.ChurchFamilyDataSet.tblMemberDependents)
Me.TblMemberContributionsBindingSource.EndEdit()
Me.TblMemberContributionsTableAdapter.Update(Me.ChurchFamilyDataSet.tblMemberContributions)

When I installed VS 2005, it installed the default version of SQL Server 2005 Express that ships with Visual Studio 2005 installer media.
How can apply SQL Server 2005 Express SP1 to update this existing instance?
Currently, if I run this query:
SELECT @@version
I get the following:
Microsoft SQL Server 2005 - 9.00.1399.06 (Intel X86) Oct 14 2005 00:33:37 Copyright (c) 1988-2005 Microsoft Corporation Express Edition on Windows NT 5.1 (Build 2600: Service Pack 2)
After applying SP1, I should get 9.00.2047.00.
Should I just go to this link and download & install the SQL Server 2005 Express Edition SP1:
http://msdn.microsoft.com/vstudio/express/sql/download/
Thank you,

I am new here and new to SQL Express. I've searched for my issue, but can 't quite find anything close to the problem or how to solve it, if it's even solvable. I am using SQL Express on a pc to connect to the back end of a database. The front end application (an access runtime) also runs on the same pc. This pc is on a domain. I think I've tried every combination of protocols, and although connectivity via ODBC is successful, the application can't connect - gives the "server doesn't exist or access denied". When I log on to this computer with the "machine" logon (not the domain), I have SQL Express configured to use shared memory, the application runs just fine. I need to use this database for testing in a non productivity environment, but I really hate to log off the domain to run it. Ideas?
Thanks,

My Sql express will use up to 1G or more memory and never release.
I had the same problem on SQL 2005 standard, I solved by adding /3G in boot.ini and turn on AWE.
but it seems SQL express doesn;t support AWE. so how could I do here?
thanks
