SQL Express Connection Limit
Mar 15, 2006
What is the connection limit of SQL Server express. Currently I am using Access database and it allows < 300 concurrent connections. The database is supposed to be accessed through a web page. If there are hundreds of users hitting the page and updating the database, will there be any synchronization issue. How many concurrent connections can be opened?
Thanks

Hi all,
I have recently moved over from SQL Server 2000 to 2005 and am now having an issue with my application with what appears to be, the number of recordsets that I can open/close on a single connection.
Here is a snippet of what I'm doing, in VB 2005 using ADO... (assuming the connection is already open and working)
Dim RS1 As RecordSet.
DIM RS2 As RecordSet
RS1.Open("SELECT...")
Do While Not RS1.EOF
count = count + 1
Console.Writeline(count)
RS2.Open("SELECT...")
..some processing...
RS2.Close
Loop
RS2 = Nothing
RS1.Close
RS1 = Nothing
Now as I said this all works fine when I connect to an SQL 2000 server but on SQL 2005 it bombs out when 'count' is approximately 1940 with an exception saying that the login failed. If I have Server Management Studio open, that connection will then freeze and throw up an error about how only one usage of each socket address is normally permitted - I think thats more a red herring though.
Any ideas? I've been through all the server settings and can not seem to find anything about recordset limits or timeouts. The only way I've been able to get around this problem at present is to open a new connection object for each iteration to be used by RS2.
Thanks everyone. Any pointers would be much appreciated.

Can someone help me with the following problem:
I'm a SQL server DBA and we sell intern SQL-Server resources to the application teams based on needed storage and number of users.
I have several servers shared by different application teams.
Now I'm looking for a method to limit the number of users working together on a specified Database. Because when a project manager wants resources for 100 users I want to be sure that only 100 users can connect to that particular database at the same time.
I know I can limit the number of connections on server level but I need this on Db level too.
Can someone help me?

If I deploy a database to the web using sql express 05 is there a limit to the number of connections that can be made on it? I have read posts stating that but cant find any documentation from MSFT that supports that idea. I just know that it has a limit of a db size to 4 gigs.
Thanks!

Any one knows for sure if there is any limit on the number of characters/letters that a FLATFILE connection manager can maximally have?
Is the following name (36 letters) valid ?
Code Snippet
<DTS:Property DTS:Name="ObjectName">Load Ready Output Connection Manager</DTS:Property>

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

Okay, I know the maximum size limit on a database in SQL 2005 Express is 4GB, but what happens when you exceed that limit? I can't seem to find much info on that topic. What kind of error return would you get from a stored procedure attempting to do an insert that will exceed the 4GB limitation? Also what factors go into that maximum size, factors that might not be completely obvious of course?

Hi,
In MySQL,
"GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.1.1' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;"
This gives the permission to 'root' user from '192.168.1.1'. Another user or another ip couldn't connect to this server.
In SQL Server 2005 Express, can I implement like above query statement?

All --
Please help.
I have some questions about connection strings.
BACKGROUND...
Note that I am using the "SQL Native Client OLE DB Provider", SQL Sever 2005 Express, ASP.NET, C#.NET, and VS.NET 2005.
Note that I do not want to use the "Attach a database file" type of connection string.
Note that I am using the site http://www.ConnectionStrings.com as a reference.
Note that this "Standard security" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Uid=MyDatabaseUser;Pwd=MyDatabasePassword;" />...does not work and causes the following run-time error...A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)
Note that this "Trusted connection" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Trusted_Connection=yes;" />...works but is less-than ideal because it uses a Trusted Connection rather than a Username/Password combination.
QUESTIONS...
(A) What exactly does the error in Item 4 mean?
(B) Do 4 and 5 imply that one must use a Trusted_Connection for all SQL Server 2005 Express connection strings when the database does not reside in the web application's App_Data folder or use a "Attach a database file" type of connection string?
(C) Are there any alternatives?
(D) What do you suggest?
Please advise.
Thank you.

Hi all,
I have SQL Server Express and VB 2005 Express installed in a Microsoft Windows XP Pro PC that is a terminal PC in our office Network. My Network Administrator has granted my terminal PC for Administrator Use. I tried to do the ADO.NET 2.0-VB 2005 programming in my terminal PC and I could not get a remote connection in the Window Form Application via Window Authorization. I do not know how to make this kind of remote connection in my Network. Please help and advise.
Thanks in advance,

Hi
I have VC++ express and MSSQL SMS express and have an application working nicely locally. The Data explorer and data connections part works really easily.
Now, I want to make the application available to my home network.
I mapped the drive where the database is and called it Z: so I could put my "release" on my other network PC and assumed it would find Z: if I mapped the shared network drive on that machine and called it Z:
But: I can't even add the mapped connection on the local machine, I get:
The file "Z:databasescalorie.mdf" is on a network path not supported for database files. An attempt to attach.....etc"
It works fine on the original F drive.......
Am I approaching this the wrong way. How should I distribute to network PCs?
thanks hopefully
David

I am new to VB.Net coming from a VB6 background using the VB.Net Express and have even loaded the SQL Express. The learning curve is not to bad until you get to dealing with connecting to db's. However, in trying to fill a grid with data, manipulate it and then update it has not been any fun either. There does not seem to be enough information out there dealing with these two as of right now.
Anyway, trying to add a datasource connection for a grid has resulted in a real problem even using the connection wizard. I keep getting the same error that the default settings for SQL express does not allow remote connections. However, I thought that I have corrected that. Unfortunately, with VB express I cannot even seem to talk to my SQL 2000 server either because it gives me the same exact error. I am thoroughly frustrated with it and ready to just do it in VB6.
I am open to any thoughts on this. I do not like using bound controls, except in a few situations. I would like to create it unbound if at all possible. If someone could give me some ideas as to what to do and where to go with this I would appreciate the help. I have been doing a lot of reading and a descent understanding what is needed to talk to a SQL db.
Thanks in advance.

Hi,
I am relatively new to this. I have installed VB 2005 and that has installed a version of SQL Server 2005 Express on my local development machine. I am using VB to develop some demo sites and i can create DB's in the App_Data file and they work when I test and run then by pressing Ctrl + F5.
However i have some demo tutorials that require Northwind and Pubs to do them. So i have installed Northwind and Pubs using the cms prompt and the InstNwnd.sql install. They said everything has been installed fine.
This is where the problem starts. I open new connection in VB, or asses for that matter and try to open my local server machine (just my desktop running WindowsXP pro), Which is called Optiplex. Sometimes i get the optiplex appear in the dropdown that asks for your to choose a server and other times it doesnt. Eevn if the machine appears it doesnt let me chose Pubs or northwind from the second drop down.
I think i must have SQexpress running on the machined named Optiplex because i have the SQL server configuartion manger on it. That tells me i am running SQL Server(SQLEXPRESS) and SQL Server Browser both switched on and running. By the way i have set my SQL manager to run as Local service.
One thing that i consider strange is that when i have had SQLServer Express running on other machines normally there was a little icon running in the right hand corner of the the task bar.
Does anyone know what is going on with my mchine and have i got the SQL server setup correctly?
Just one last piece of additionally information is that i have a folder called C:SQL Server 2000 Sample Databases which is where the MDF files are located.
Thanks a million Sanson

Hello everybody
Im writing an application in VB6 (with sp5) and using SQL Express 2005 for database. I need to run this application over the network with clients working on Winxp and Win98 also.
I've used the connection string as
con.connectionstring = "Driver={SQL Server};Server=Factory;Database=Production;Trueste _Connection=yes;"
con.open
This works fine the the host system(where the SQL express is installed) but if i try to run the applicatoin from a network PC, running on Windows 98, Im getting an error
"Login failed for user '' Factory/Guest"
When i Change the connection string to use User id and password of SQL Logins , (The user is set 'Public' as DB Role membership in SQL Express for the Production database)
con.connectionstring = "Driver={SQL Server};Server=Factory;Database=Production;UID = dbUser PWD=Pass;"
con.open
I'm getting an error : The user is not associated with a Trusted SQL Server Connection
How can i resolve this problem,
please suggest some remedy...
thanks in advance...

I am having the worst time getting connect to my database.. I just get error. But I have read somewhere (microsoft) that SQL Express can't have over 1gb of ram. My pc has 2gb will this stop me for building the sites and connecting to it? Do I need to upgrade my PC and the webserver to sql workgroup for me to be able to work on this.
2 question. Can I just upgrade the server and connet to the server from my pc to build the basic pages in Dreamweaver in the web.config file as long as my PC is online? This way I don't have to buy it for my PC as well. If this is possible what would be a connection string i would use in the web.config file to make this work.
Thanks you

Hai,
We created one application, with deployment. When we install the
application on another machine, it will attach a database in sqlexpress
instance. For eg. c:Programfilesoursoftwarenamekmsdb.mdf.
Now i am having one more webservice running on that machine as
dll(not webservice source code). In this web service i am reading that
database values. But the connection string is giving some error
message.
actually my coding is
sCon = "Server = ./SqlExpress;Database =KMSDB;Integrated Security =
SSPI;"
gsCon = New SqlClient.SqlConnection(sCon)
If gsCon.State = ConnectionState.Closed Then
gsCon.Open()
End If
sQuery = "SELECT KeyCode 'Key Code',Status
'Status',UserCode 'User Code',JobCode 'JobCode' " & _
" FROM KeyHolders"
oDaKeyHolders = New SqlClient.SqlDataAdapter(sQuery, gsCon)
oDaKeyHolders.Fill(oDsKeyHolders)
For this I am getting the error is
"Cannot open database "KmsDb" requested by the login. The login failed.
Login failed for user 'DESIGN-EMB2user'."

Raju

I have recently installed SQL Server Express on a desktop machine for a program that we use. I am in need of adding additional machines to gain access to the server for the database. Right now, the program is working on the local machine fine. What do I need to do or enable for access on a local LAN? All machines are XP Pro on a workgroup. Also, the software we use has a remote connection manager that requires inputting the server address for the machine. Is it better to use the computer name or IP address, and then what is that format? SQL Instance name is 'uesafh' if that helps. Any other information that I can provide, please let me know.
Thanks!

If I create any other user (test, felix, fido, etc) in my database, that user can login successfully through Management Studio Express except not through an ODBC connection. Thus, this is a very bizarre issue. I have made sure this user has the same roles as SA. My instance is configured to handle SQL Server Authentication and Integrated. This works fine in Studio Express, but not in the ODBC connection.
When using "SA" login, I can connect to Management Studio Express and through an ODBC connection. Seems rudimentary enough, however, if I change the name in the ODBC connection i get
"Connection Failed,
SQLState '28000', SQL
Server Error 18456,
Microsoft SQL Native Client SQL Server Login failed for user 'xyz'"
Any ideas? Do I need a different ODBC Administrator?

I have a problem connecting with Sql Express. Here is the setup: 3 machines, all running SqlExpress on XP.Machine 1 is a notebook, and machines 2 and 3 are Tablet PC's. I seem to have all 3 set up identically, and can connect between 1 and 2. However, Machine 3 is the problem. From 1 and 2, I can "see" the instance on 3 but not connect, and from 3, I can "see" the instances on 1 and 2, but not connect.
I have read through the docs and have SqlBrowser on and configured, I turned off the firewall on 3, and have Sql SErver enabled for remote connections on all three machines. I have perused the security settings for Sql on 3 and it appears to be the same as the other two machines. I have matching administrator accounts on all 3 machines.
The connection error is the standard one about can't connect or don't have privileges.
I think this is a network problem and here is why: I used to use machine 3 at work. My employer's IT dept set it up to give me network and internet access. Although I can "see" the SqlExpress services in SSMS, I can't expand the network node using Windows Explorer on machine 3, and I can't access the shared folders on machine 3 from machines 1 and 2.
Is there a networking setting that may be preventing me from connecting to the other machines?
thanks,
Steve

Hi,
i am stuck in a strange situation.
I have successfully built my application setup through InstallSheild 12. Which first installs SQL Express user define instance as a pre-requisite and then install my application files. First time when i run my application (without restarting the pc), it connects successfully with user define instance.
But as i restart my PC and try to open my application, it is not connecting with database.
i am using the following command line to install SQL Express 2005 user define instance:
"/qn ADDLOCAL=SQL_Engine INSTANCENAME=MyInstance SECURITYMODE=SQL SAPWD="test" AUTOSTART=1"
if i change Remote connection to "using both TCP/IP and named pipes" through "SQL Server Surface Area Configuration" and then restart my pc again. My application connects successfully with Database.
Please guide me where i am getting wrong in building setup. do i have to add something in my command line to not get this error

Hi folks.
I'm having some issues getting started using C# and SQL Server Express.
I'm trying to create a C# project to just connect to a SQLSE DB just so I can start learning how to use it. I've used the SQLSE Surface Area Config Utility to enable remote and local connections, and it gives me error 26 about the default config not allowing remote connections.
I then altered the connection string from .SQLEXPRESS to .MSSQLEXPRESS which is the instance of the service running on my PC. When I do this, it throws error 25: invalid connection string. I also have ensured that the 'User Instance' field is set to True (but I have tried it set to true and false, with no change: error 25 is still thrown).
I would appreciate any help.

I´m developing an application for PDA that have to connect with a SQL server running SQL espress 2005. First I
coded the app to run on the server machine in windows forms and works fine. Then I coded the app under compact
framework in order to run on a remote PDA and I have connection problems. I´m doing test with visual studio
emulator running in the same computer that sql server is.
I configured sqlserver to allow remote connections and use tcp/ip and named pipes.SQL browser is running too.
The firewall is disabled. I´m using windows auth. I used different users, used different connection strings but
I can´t connect to the server. I have read this configuration web:
http://blogs.msdn.com/sqlexpress/archive/2005/05/05/415084.aspx
The last connection string I used is: Server=192.168.0.3;Initial Catalog=dbase;User ID=guest;
In the connection string I added port 1433, servername instead IP, different users id...but can´t connect.
I can ping visualstudio emulator from sql server, now are in the same lan but in future pda have to connect to
server using gprs.
Where is the error??
Thanks in advance.
PS. I´m reading some post that indicates SQL Server Express doesn´t allow any remote connection?
