Knowledgebase: MSSQL
Do you have a connection string I can use to connect to the local MSSQL database?
Posted by Arvand Sabetian (Import) on 19 May 2009 05:13 AM

Yes. Please use the following connection string and fill in the necessary spots with your database's information:

 <add name="strConn" connectionString="Data Source=localhost;Initial Catalog=DBNAME;Integrated Security=false;User ID=DBUSERNAME;Password=DBPASSWORD" />

In some instances, the "Data Source" will need to have the Instance Name after it(\sqlexpress), such as this:

<add name="strConn" connectionString="Data Source=localhost\sqlexpress;Initial Catalog=DBNAME;Integrated Security=false;User ID=DBUSERNAME;Password=DBPASSWORD" />

DBNAME is what you specified as your database name in the control panel
DBUSERNAME is the username you created to connect to the database (and was associated with the database in the control panel)
DBPASSWORD is the password you associated with the username above

An example script:

<%@ Import Namespace="System.Data.SqlClient" %>
Dim conn As SqlConnection
Dim sqlQuery As SqlCommand
Dim dtrTbl As SqlDataReader
conn = New SqlConnection( "Server=localhost\sqlexpress;uid=USERNAME;pwd=PASSWORD;database=DBID" )
sqlQuery = New SqlCommand( "Select COLLUMN_NAME From TABLE_NAME", condDBID)
dtrTbl = sqlQuery.ExecuteReader()
While dtrTbl.Read()
Response.Write(“<li>" )
Response.Write(dtrTbl( "COLUMN_NAME" ) )
End While

these connectionstring does not work and shows up an error massage
please specify more support including fewer examples how we can connect to the database and how to confugure config file.

Is there a remote connection string I can use to connect to my database from another web application on a different site? Godaddy is horrible and does not allow remote access to their database. So if I can establish a connection from my web app running on my godaddy hosting account, then I can SELECT data from the database and INSERT over a separate connection.
15 October 2010 01:16 PM
The connection string is just an example. You can connect remotely so instead of using localhost or, you would use your domain name or the hostname of the server (or its ip address) to connect remotely.

How do i know the host name of my database server
17 February 2011 10:45 AM
I have tried everthing written but all to no avail. Please Give me for more information
Arvand Sabetian
11 March 2011 03:00 AM
The hostname is your domain name if the domain is pointing to the server or
25 April 2012 09:44 AM
This should really be more clear. I don't know why the control panel doesn't create a connection string for you like godaddy does. This is terrible. You Arvixe's customer support told me that the host name was localhost... Obviously they don't know what they're talking about.
24 February 2011 09:04 AM
I connect remotely via VS2010 and in the web.config without error using the server info and format below:

In VS2010:
ServerName = the catalog and other info is from the db you set up on the server.

In Web.config: (only a space between attribs)
<add name="myConnName"
connectionString="Data Source=&quot; &quot;;Initial Catalog=myDB;User ID=myID;Password=myPASWORD"
For Membership Providers you can have something like:
<add name="AspNetSqlMembershipProvider"
applicationName="/" />

For Role Provider:
<add name="AspNetSqlProfileProvider"
connectionStringName="myConnName" applicationName="/" />

<roleManager enabled="true">
<add name="AspNetSqlRoleProvider"
applicationName="/" />
<add name="AspNetWindowsTokenRoleProvider"
applicationName="/" />

this doesn´t work for me. I don´t want to travel to the moon, really.. I´M SIMPLY TRING TO USE THE DEFAULT ASP NET MEMBERSHIP SYSTEM ON MY SITE
for example, this connection string:
<add name="ApplicationServices" connectionString="data source=.\SQLEXPRESS;Integrated Security=false;AttachDBFilename=|DataDirectory|aspnetdb.mdf;" providerName="System.Data.SqlClient"/>
drops this error:
Login failed for user ''.

You are trying to attach a database which is not possible. You'll need to obtain a .bak file for your database and restore it through the control panel. Once you've done so, please then use one of the connection strings outlined in this KB with the proper database, username and password.
16 March 2011 11:08 AM

All this guy wants is default membership feature. to do that needs to have an access "aspnet" database that contains all information about ASP.NET applications services. To achieve that:
1) create a new DB for him and run aspnet_regsql.exe on it (aspnet_regsql.exe -S DBServerName -U DBLogin -P DBPassword -A all -d DBName); This will create all tables and sp. Then give him the connection string;

2) Option 2 give him access to exsisting "aspnet" db and give him the connection string;

-use code provide by Themingware with connection string that points to that new created DB by Arvand

I've tried #1 with several users and it hasn't worked for them. However, we're always willing to try things to make sure customers get their apps working exactly the way they want. Ariel, I would suggest opening up a support ticket and then email qa .at. with your ticket information.
Dan Lipsit
28 March 2014 11:36 AM
not sure if anyone posted this yet but for aspnet membership provider just run aspnet_regsql.exe locally on your machine. Then from the GUI you can point it at your DB.

For getting the connection string, it is super easy. Just create a new data connection through server explorer in Visual Studio and connect to your db using the same credentials as you do through SSMS. Then, right click on your data connection and select properties. The connection string is right there, just copy and paste it into your web.config (obviously replacing the **** for password with your actual password)

I am a brand new customer of Arvixe (and very happy to be one). I have received so much help from various forums, it is time for me to contribute. I have been struggling with the exact same problems and finally resolved them.
Inga is correct about #1, but the successful approach I used was to do it on my local machine, use SQL Server Management Studio to back up the database, upload the backup to my website, and restore it using the Restore from the Control Panel. I struggled with the connection string (quite a bit of time because I was misspelling arvixe), but finally got it working following Themingware's advice. Thanks to Arvand, Themingware, and Inga. Arvixe is the greatest!!!

I am able to query my data in the my database but not can not insert data to my table. It does not give me any error message. Could someone help me about it?
Arvand Sabetian
11 April 2011 03:31 AM
In that case, I would be a 100% sure its not a connection string issue and coding issue. If you can query your database, you should be able to insert and if there is a database error, you would get an error. Therefore, I suggest looking over your code again.

Is there a way to connect to SQL2008 using visual basic 6.0 - I have an old application and do not want to shift it to

I tried this but did not work -

Conn="Provider=SQLOLEDB; Data source=websitename; UID=db_username; PWD=db_password; database=database_name;"

Arvand Sabetian
02 June 2011 11:13 PM
I would suggest posting this on our forum or support as we need the error and we may have the error explained here in the KB or on our blog/forum.
07 June 2011 10:17 PM
Hi.. Anirudh
use Provider name "SQLNCLI10" instead of "SQLOLEDB"

I just joined arvixe yesterday, and have managed to do a .BAK restore of my SQL Server 2008 database. Now I need help with the connectionString in my web.config. I read through this blog, and am still lost. I joined arvixe to try uploading an ASP.Net MVC3 project. Here is my connection string that works on my local machine:
<add name="ProductEntities" connectionString="metadata=res://*/Models.ProductDataModel.csdl|res://*/Models.ProductDataModel.ssdl|res://*/Models.ProductDataModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=.\SQLEXPRESS;attachdbfilename=|DataDirectory|\Products.mdf;integrated security=True;user instance=True;multipleactiveresultsets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />

I tried substituting the data source:
<add name="ProductEntities" connectionString="metadata=res://*/Models.ProductDataModel.csdl|res://*/Models.ProductDataModel.ssdl|res://*/Models.ProductDataModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;data;attachdbfilename=|DataDirectory|\Products.mdf;integrated security=True;user instance=True;multipleactiveresultsets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />

I am not sure what the connection string needs to be for Entity Framework and MVC 3 on Arvixe.
Arvand Sabetian
24 June 2011 04:35 AM
Per the above example, you should be using Initial Catalog=DBNAME;Integrated Security=false;User ID=DBUSERNAME;Password=DBPASSWORD instead of attachdbfilename=|DataDirectory|\Products.mdf;
Elizabeth Gee
06 July 2011 07:49 PM
I get this error when I try this connectionString:
Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path. Please make sure the user has a local user profile on the computer. The connection will be closed.
[EntityException: The underlying provider failed on Open.] click on Products or Categories

It appears that your application is not using the data source that you've mentioned in the comment. The error you've encounter is generally seen when your application is attempting to attach a mdf file to the application or create a new one.
Daniel Bradish
13 July 2011 06:31 AM
I struggled as well getting my MVC 3 application to connect to the database, but I did get it working. Here's the connection string I used. You do have to tweak the one generated by the framework:

<add name="PalMateOnlineEntities" connectionString="metadata=res://*/Models.PalMateOnline.csdl|res://*/Models.PalMateOnline.ssdl|res://*/Models.PalMateOnline.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=localhost\SQLEXPRESS;initial catalog=DBNAME;Integrated Security=false;User ID=USER;Password=PASSWORD;multipleactiveresultsets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />

Good luck!
19 July 2011 06:03 AM
dear arvixe, I have the same problem with. i got a server error after I uploaded my site. I inquired before i got a hosting plan from you and I was informed that .MDF file will work directly without any changes. That's the reason why I got your hosting plan. So please dont give me an email saying refer to this site. I want my site as is. so please help me. make my .MDF file work. thank you
Arvand Sabetian
25 July 2011 09:03 AM
You can not directly connect to a mdf file. You must backup your databases locally to a .bak file and restore on our side.

I am new to arvixe and db hosting. I've also struggled to connect to my db but in the end managed to solve my problem self.

I believe some of the solutions above is good but did not help me much.
Here is the string that I am using and works good. Perhaps it can help others to.

<add name="TestDB.MySettings.ConnectionString" connectionString="Provider=SQLOLEDB;Data,1433;persist Security=False;Initial Catalog=DBName;User ID=MyUser;Password=password"
providerName="System.Data.OleDb" />

I'v add ,1433 (sqlport) to my domain name and change from Integrated Security=false to persist security=false.

This is the connection string I used for my app...

<add name="DataContext" connectionString="Data,1433;Initial Catalog=DBNAME;Persist Security Info=false;Integrated Security=false;User ID=ForJandS;Password=password" providerName="System.Data.SqlClient"/>

Note: I did have tons of issues at first using Entity Framework, because there were DB permission issues...The issue was on the creation of the tables...make sure when viewing the table it says dbo.TableName and not user.TableName.

If you right click in MS SQL management studio and add a table, it will be created as user.TableName!!! and this causes all kinds of issues with entity framework and stored procedures.

IE: CREATE TABLE [dbo].[TableName] vs CREATE TABLE [USER].[TableName].... that was the difference!

22 March 2012 02:29 AM
I just joined Arvixe yesterday. I installed my site, it works, but when I try to connect to the database I get an error message:
System.Data.SqlClient.SqlException: Cannot open database "TestDB" requested by the login. The login failed.
Login failed for user 'TestUser'.

I am using the same connection string as Arvand suggested:
Data Source=localhost\sqlexpress;Initial Catalog=TestDB;Integrated Security=false;User ID=TestUser;Password=password

Can there be some kind of security setting for my DB that I could change in the control panel? Or any other advice?

Some points that might be related to the problem: when I am trying to connect to the DB through SSMS, I get to the point where I see the list of databases, but when I want to access my DB, I get a message The database is not accessible.

Also, I created a .bak file for my DB, but could not Restore it in control panel. I had to call the support, FTP the file and they restored it for me.

My site is built in VS2010. I disabled firewall for now.
22 March 2012 02:36 AM
I think I just figured it out. There is a checkbox next to the username in the control panel and it was not ticked. Once I ticked it I could log in :-)
Michael Carr
26 March 2012 05:53 PM
Yes that is correct. The check box is granting access for that database user to connect to that specific database. Any database user that you create will need to have this set for each database that you would like them to have access to.

You have an error in the connection string, it sounds like the server name is not correct. If the script is running on the local server you can try using localhost or for the server name

The DBNAME part of the that the name I created for the database or the Logical Name shown as db3*******?

That would be the actual name of the database you have created that you are wanting to connect to.

30 July 2012 09:40 AM
I've tried nearly every connection string imaginable, including those listed above. I currently have this is in place, as it gives me the least amount of headache:

Data Source=localhost\sqlexpress;Initial Catalog=vp1;Integrated Security=false;User ID=userid;Password=password

I'm trying to install nopCommerce 2.5. and this seems to create the database, but not allow me access. I get the following error:

Setup failed: System.Exception: Database does not exist or you don't have permissions to connect to it at Nop.Web.Controllers.InstallController.Index(InstallModel model)

The database does exist--its there in all its glory. I just can't get the credentials to work it seems. Were talking MVC 3.0 and ASP.Net 4.0.

Any other options?
Michael Carr
01 August 2012 11:08 AM
In the control panel, you must also ensure that the database user you have created, has been granted access to the database itself. assuming the username and password are correct in your connection string, that is the next thing I would check.
Jeremy Janes
30 July 2012 09:49 AM
Oh, Goody. Now we are getting somewhere. Made a quick tweak to things based on suggestions on the nopCommerce boards and get the following error:

"We're sorry, an internal error occurred that prevents the request to complete.

Our supporting staff has been notified with this error and will address this issue shortly. We profusely apologize for the inconvenience and for any damage this may cause. You might want to try the same action at later time."

Connection string now looks like this:

DataProvider: .\sqlexpress
DataConnectionString: Data Source=localhost;Initial Catalog=vp1;Integrated Security=false;User ID=userid;Password=password
Michael Carr
01 August 2012 11:05 AM
The error sounds like a 500, and is usually not related to the connection string. Seems you have corrected one error to locate another. You can try enabling detailed error logs from the control panel and get more specifics. The option is located under web > websites > domain name > error tab

The Data Source does not sound correct, instead of try using your actual domain name, the server name, or if the script is running locally on the server, use "localhost" or the IP ""

Is it possible to user Integrated Security to allow the site to connect to the database without storing the password in plaintext?

Arvixe already has a setting for Dedicated Application Pool in the control panel. If I understand its function correctly, then every website will have a unique application pool. It is possible then to add the IISAPPPOOL\POOL_NAME to the database logins. This would securely give your website access to the database without ever storing a password in plaintext
Michael Carr
01 October 2012 11:28 AM
Every site has a dedicated application pool but we do not allow integrated logins for database connectivity. They have to use SQL login

I have been trying since a long time to upload my db to the SQL server 2008 hosting, but I can't do it. UI have tried to make a .bak and then restore it to the server and I am still facing problem to restore it.
I guess the fig hacve nothing to do with the upload of the .bak file to the server. But what am I supposed to do before I Upload my .bak to the server?
Michael Carr
06 November 2012 06:34 PM
You can restore your .bak file directly from the control panel. Our staff can also do this for you, if you would like you can upload the .bak to your account using the file manager and have a member of support restore it to any database that you would like.

For deployment purposes in Visual studio, you can add a web config transform file which will create a web config.debug file and a web config.release file. By right clicking on the current web config file in your Visual Studio project, select Add Config Transforms. If you are using the web config.release file then use the Active(Release) configuration in the Package/Publish SQL tab. This will add the web config.release file into Arvixe's server without changing the old web config file and without adding the web config file to their server. In the web config.release file you can add <connectionStrings>
<add name="YourConnectionString" connectionString="Data;Initial Catalog=YourDatabse;User ID=YourUserID;Password=YourPassword"
providerName="System.Data.SqlClient" xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/>
</connectionStrings> Under Package/Publish SQL Settings which is under My Projects, you can click on Import from Web.config to upload the source database connection string. In the Connection String for destination Database you can use the connection string in the web config.release file. Under Package/Publish Web settings, select "include only files needed to run this application" and choose exclude App_Data folder. Click on the Project tab in the menu bar and select Build Deployment package. Then click on the build tab on the menu bar and Select Publish "Your Website". For the publish method select FTP and the target location is Select passive mode and enter your User name and password for your domain. Then click Publish.

Your connections are being made to a remote server, at you need to copy your SQL data to the local server, and then adjust your connection string to connect to the local server.

The solution depends greatly on the connection error you are getting. If would start by changing the server name to If that doesnt help please create support ticket with the connection error and I am sure we can get it fixed for you.

You should be able to use this connection string in the MVC application.
<add name="YOURDBContext" connectionString="Data Source=YOUR SERVERNAME;Initial Catalog=DATABASENAME;User Id=YOUR DATABASE USER; Password=XXXXXX;Integrated Security=False" providerName="System.Data.SqlClient" />

If you are having trouble using the entity framework for MVC, this worked for me:

- I was able to create a new user, but whenever I tried to access my database, I was getting the error: "An error occurred while attempting to initialize a System.Data.SqlClient.SqlConnection object. The value that was provided for the connection string may be wrong, or it may contain an invalid syntax.\r\nParameter name: connectionString"

- For some reason, using 2 connection strings fixed it. The role provider, profile provider, and membership provider all reference a connection string that is in this format: <add name="ConnectionName" connectionString="data;initial catalog=yourdbname;user id=yourusername;password=yourpassword;Integrated Security=False" providerName="System.Data.SqlClient" />

- Then, whenever creating an entity context in a controller, this string is passed through as a parameter (note: this is just a slight modification to the auto-generated string): <add name="AnotherConnectionString" connectionString="metadata=res://*/yourdatabase.csdl|res://*/yourdatabase.ssdl|res://*/yourdatabase.msl;provider=System.Data.SqlClient;provider connection string='data; initial catalog=yourdatabase;user id=yourusername;password=yourpassword;Integrated Security=False'" providerName="System.Data.EntityClient" />

And I haven't had an issue since. If anyone could let me know why this even works I'd appreciate it. But, it appears to work for both debugging locally and publishing.

I finally found how to get Profile providers working with the default database.

You basically have to take a backup of the local database, and then modify the profile providers as follows:


<add name="AspNetSqlProfileProvider"
connectionStringName="DefaultConnection" applicationName="/" />


Basically the same thing as the other forms, however you need to take a backup of your local database and restore it to the remote database. Otherwise the functions and stuff will not transfer to the remote database. I'll be writing a quick guide on this a bit later.

Hi All, I have ready many posts here, but I cannot connect. I can connect via SSMS, but not with my connectionstring via MVC app. (I was able to connect to my local, but not Arvixe remotely.

My connection string
<add name="MyContext" connectionString="Data;Initial Catalog=BumperMedic;User ID=myUserId;Password=MyPassword" providerName="System.Data.SqlClient" />

My Error:

{"An error occurred while getting provider information from the database. This can be caused by Entity Framework using an incorrect connection string. Check the inner exceptions for details and ensure that the connection string is correct."}

Inner:{"The provider did not return a ProviderManifestToken string."}

{"A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)"}

{"The network path was not found"}

Please help.

Normally it is due to a bad username or password, ensure user id= the user for the database and you have granted that user access rights to the database. A common mistake is to insert your account username in that place. If you are unable to resolve the problem please open a support ticket so we can see the exact specifics of your connection string.

Microsoft has some good guides on this. Start with this one :

Is this error because of Connection String :

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

Yes, from your error it sounds like the data source is not correct.
