How Many Connection Sqlexpress Supports
Mar 8, 2006
I see this question a lot, so I thought I would go ahead and post the answer here.
Q: How many connections does SQL Server Express support?
A: Unlike MSDE, SQL Server Express does not limit connections. SQL Server Express supports:
1 gb RAM (note the machine can have more memory, but 1gb will be used by SQL Express)
1 processor (again, the machine can have more, but just 1 proc will be used by SQL Express)
4 gb database size (note, there can be multiple databases, but none of them individually can be more than 4 gb)
Hope this helps,
Thanks< MJ

Hi guys.
I have Windows XP pro with IIS + sqlexpress
My problem is, I am writing a code with classic asp, to connect to sqlexpres database and somehow something blocking me. My first try was unsuccessfull , it was keep getting timeout. then I did something and now I am getting this error message shown below;
Error Type:
Microsoft OLE DB Service Components (0x80040E21)
Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.
/myfolder/opendb.asp, line 5
I am using SA user to connecto the server. When I checked the server with managment tool I found out sa doesn't have permission to use this new database of mine. So I tried to add that by going into
Security>logins>SA >properties > usermapping. Then I found and checked the new database . I get an error message shown below;
Create failed for user 'sa' (microsoft.sqlserver.express.smo)
additional information:
an exception occured while executing a transact-sql statement or batch.
(microsoft.sqlserver.express.connectioninfo)
Cannot use the special principal 'sa' (microsoft sql error, error 15405)
--------------------------------------------------------------------------
Also my second question is I downloaded web data administrator and I do not know how to login. what is the default username and password??
I thankyou very much for the help ahead.

So i get this version of sqlexpress up and running and i copy all my databases over on to it. Redo my Logins for te server and then add the the DSN to ODBC admin console.
And still no good >:_( this is the error i get:
[Microsoft][ODBC SQL Server Driver][SQL Server]Cannot open database "publicSite" requested by the login. The login failed.
So i know im doing somthing really stupid.
So heres what i got:
ASP connection srting looks like this:
<%
// FileName="Connection_odbc_conn_dsn.htm"
// Type="ADO"
// DesigntimeType="ADO"
// HTTP="true"
// Catalog=""
// Schema=""
var MM_PublicSiteJS_STRING = "dsn=publicUSR;uid=publicUSR;pwd=**********"
%>
now it ther a special ODBC driver used for SQLExpress or can i use a standard SQL driver?
any help would be much apriciated.

Hi,
I write a .NET Windows Form that connect to SQLExpress datafile. After updating data, I want to zip the .mdf file and send email. However, I got an exeption that the .mdf file is used by other thread so I cant zip. Even I try to close all connection, I still cant zip.
Is there any way to detach/unlock .mdf file connecting by SQLExpress?

I installed on a w2k/sp4 local machine SQLEXPRESS.
I copied the database also to the localmachine
With the sqlexpressmanager I attached the database. Everythinks looks fine.
I quit the manager, but then I start the manager again. Now the manager can't find the sqlserver.
Timeout Expired is the message.
Why is that? I installed SQLEDXPRESS on a lot of machines. No problems. But those machine the manager lost the connection after the first time.
thanks again.

i got an error just like that.What must i do?
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

#!perl
I am having difficulty converting my CGI(perl module) connection from mySQL to SQLexpress. Does anyone know what the connection string should look like?
Listed here is my current connection string. I'm trying to get this done this week. Please email me if you have an answer in addition to posting.
$dbh = DBI->connect("DBI:mysql:database=$var{database};host=$var{server}","$var{root_username}", "$var{root_password}",{'RaiseError' => 0, 'PrintError' => 0});
Much appreciated,

Hi all,
I followed an excellent tutorial (from Microsoft) about creating and using a SQLExpress db table internal to your website and the site I created works just fine - locally. When I publish to my web host provider I get this error:
[SqlException (0x80131904): An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)]
My web host provider supports .NET 2.0 but doesn't support MS SQL Server. But that should matter - right? Because I'm putting the db instance right in the website?
I did a search and followed some of the advice:
I went into the SQL Server Surface Area Config Mgr and set SQLExpress for local and remote connections and rebooted/republished. I also have SQL Server 2005 installed as a separate entity (if that makes a difference).
I still get the above error. This is the connection string from the web.config:
<connectionStrings>
<add name="ConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Customers.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>
</connectionStrings>
And this is the call from the markup:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT * FROM [Customer]"></asp:SqlDataSource>
Does any know the fix for this?
Thanking you in advance
Pat

I am running SqlExpress on a Vista machine as a server and accessing it from machines running XP. I could not connect with the Vista server until I turned off the firewall, despite creating exceptions for both the sqlexpress and sqlbrowser services in the firewall setup. Obviously, I don't want to run on a wireless network without a firewall for any length of time. What else to I need to enable in order to run with my firewall up? In SMSS, I could 'see' the Vista server on the network with the firewall up, but I could not 'see' the SERVERSQLEXPRESS service or connect to it .
thanks,
Steve

I am using Visual Studio 2005. I am creating an SQL database with a web enabled front end. I am using Microsoft SQL Server Management Studio to create the database objects and an ASP.NET web page created in Visual Studio for the front end. My problem is centered around the two server instances which come with Visual Studio (MSSQLSERVER and SQLEXPRESS). The database objects are being created on MSSQLSERVER by Microsoft SQL Server Management Studio. However, in a Visual Studio ASP.NET web page, when I create a new conection string using the menu functionality, in the SQLDATASOURCE object or in the server explorer, only (My Computer Name)SQLEXPRESS shows up as an option. I have tried typing (My Computer Name)MSSQLSERVER in but the database list just comes up blank. I know that MSSQLSERVER exists because I have one active connection string to it created by a friend. They had to juggle a lot of things to make MSSQLSERVER appear and since I was just getting started then it went over my head. Whatever they did was temporary though and I havn't been able to repeat it to add new connection strings. To eliminate some of the obvious things in other posts:
*MSSQLSERVER is Started in the Services Screen
*In the configuration manager MSSQLSERVER has shared memory enabled
*On the advice of one post or proceedure I enabled TCP/IP and restarted the service (I think this is actually for remote connections everything I am doing is on one PC)
What I really want is to have things permanently set up so MSSQLSERVER always shows up as an option when creating a connection string in Visual Studio. If this means getting rid of SQLEXPRESS I won't shed too many tears.
As you have noticed everything in this is centered around Visual Studio's menu functionality. I am currently make thee code paradigm shifts.
Form -> ASP.NET
VB6 -> VB .method
ADO -> SQL
I have created some pages in ASP.NET and have started creating objects using source instead of designer.
I have automated some of the functionality on those pages using VB .method programing
While I have created some simple SQL select and bulk insert statements my SQL is still pretty weak and I haven't learned connection strings or driving changes back to the database using Transact-SQL

I am using a virtual dedicated server to host sqlexpress at a remote site. I can't get the connection from MS SQL Server Management Studio Express to connect over the Internet. I only have the box IP address (xxx.xxx.xxx.xxx) and have tried various forms of xxx.xxx.xxx.xxxsqlexpress as the server name.
Can someone point me in the right direction please?
Thanks, John

Hello, I had started my project with the express edition, then I switched to the pro one. The problem is that in my webconfig I still have .SQLEXPRESS and I don't know how to modify that to use the full version of Sql server. <add name="MyConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|MyDataBase.mdf;Integrated Security=True;User Instance=True"providerName="System.Data.SqlClient" /> When I look at the surface area manager I can see that I have 2 instances running : MSSQLSERVER and SQLEXPRESS.When starting Sql Server Management Studio I can connect to 2 servers: NEWDELL and NEWDELLSQLEXPRESS.And when I try to replace SQLEXPRESS by MSSQLSERVER in the connectionstring, then it doesn't connect.I remember having lost connection already when playing with all these tools, so I pay attention now ! That's why any help would be really appreciated ! Thank you.

Hi all,
I have a question? Whether Sql supports mutlithreads on triggers.
For example:
I have a Patient table. When two patient records getting inserted by two different transactions does it trigger the triggers in different threads and execute the code in Insert trigger Or only one row will fire the trigger and the other one won't?
Thanks

I can't start SQLEXPRESS.
The SQL ERRORLOG shows: Error is 3414, Severity 21, State 2 and says: "An error occurred during recovery, preventing the database 'model' (database ID 3) from restarting." Just prior to this, I get a warning: "did not see LP_CKPT_END".
Any thoughts why this might be and how I can fix this?

But if i try to install the same in a system which is already having SQL Express, throwing "Object reference exception" because it is not able to create the new database instance.
Can anybody help me out .

Because of numerous problems trying to get sqlexpress working, I uninstalled it with the intention of reinstalling (via Add or Remove Programs). However, now when I try to reinstall it, I get a message that the I am not making a changes so it won't let me install it.
I do have sql server 2005 developer's edition installed; is that the reason? and does that mean I cannot have both installed on the same machine?

I've searched the forum and saw that this question has been asked several times. However, none of the responses point to any documentation about this limit. We've got different groups bickering over this ("There is no limit!" "Yes there is!" "No there isn't!") and it would help to have a link on the MSDN or a response from Microsoft to this question to put this to rest once and for all. Also, if there is a limit, is that per Sql Server instance or per physical server?
Secondly, we currently have over 400 catalogs. We've noticed it takes 4-5 minutes for new data to show up in search results. Does the number of catalogs affect performance, or is it the amount of data, irrespective of catalog count?
Thanks

I added a connection (ADO.NET) object by name testCon in the connection manager - I wanted to programmatically supply the connection string. So I used the "Expressions" property of the connection object and set the connectionstring to one DTS variable. The idea is to supply the connection string value to the variable - so that the connection object uses my connection string.
Then I added a "Backup Database Task" to my package with the name BkpTask. Now whenever I try to set the connection property of BkpTask to the testCon connection object, by typing testCon, it automatically gets cleared. I am not able to set the connection value.
Then after spending several hours I found that this is because I have customized the connection string in testCon. If I don't customize the connection string, I am able to enter the "testCon" value in the connection property of the BkpTask.
Is this an intrinsic issue?

I have a package that uses a for loop to iterate through an unknown amount of excel files and pull their data into a table. However, there will be cases when the file is corrupted or has some sort of problem so that either the transformation will fail or the excel data source will fail with an oledb connection error.
Could anyone suggest a clean way to trap these errors? Specifically, the "Cannot Aquire Connection from Connection Manager", which is the excel connection.
Thanks,
