I am trying to configure my connection using SQL Server Express 2008.
Can anyone help me please. My server name is as follows: test\expressql2008 and my database is TestDatabase
My connectionstring is :
<add key="hibernate.connection.connection_string"
value="Server=localhost\EXPRESSQL2008;Database=TestMyproject;User=Me;Pwd=test;" />
It seems that the connections isn't working and I get the error:
NHibernate.ADOException : cannot open connection
Here's all connectionstrings needed
http://connectionstrings.com/
<add name="SD_ConnectionString" connectionString="Data Source=[SQLEXPRESS NAME];Initial Catalog=TestDatabase;User ID=[USERNAME];Password=[PASSWORD]" providerName="System.Data.SqlClient"/>
string con = ConfigurationManager.ConnectionStrings["SD_ConnectionString"].ToString()
Can you provide more detail about this error there could be number of reasons
1- Please check ASP.NET user has access to your database if you are using trusted connection.
2- It could be better if you create a SQL USER and assign it permission of DBOWNER to your database and with your connection use that user information.
con = new SqlConnection(ConfigurationManager.ConnectionStrings["conn"].ConnectionString);
in web.config

I am trying to create an App Service web app in the Azure Portal and to connect the web app to my local on-premises SQL Server database using the new Hybrid Connection feature.
Created a simple ASP.NET application using Visual Studio 2015 and trying to connect to the SQL server Database which is on on-prem. And modified the connection String as follows
<connectionStrings>
<add name="DefaultConnection"
connectionString="Data Source=PRAVEEN,1433; User ID=sa; Password=my_password;"
providerName="System.Data.SqlClient" />
</connectionStrings>
When the application is started its running without any errors as shown in below screenshot1.
But when I try register (enter any record) it throws me with an error as specified in the below Screenshot3....
"https://azure.microsoft.com/en-us/documentation/articles/web-sites-hybrid-connection-connect-on-premises-sql-server/" - this is the documentation to which I'm referring to..
So, can anyone from the other end help me out please...

Thank you..
#Praveen,
It is what it says - meaning Initial Catalog is missing in your connection string. It requires the Db name to connect to. You have the servername, SQLUserName, SQLPassword, but missing the DatabaseName it requires. Please change your connection string to include the the DbName as follows
<connectionStrings>
<add name="DefaultConnection"
connectionString="Data Source=YourServerName,1433;Database="YourDbName" UserID=YourId;Password=YourPswd;"
providerName="System.Data.SqlClient" />
</connectionStrings>
Look at this site to configure your connection string appropriately: http://www.connectionstrings.com/store-connection-string-in-webconfig/
After spending 6 hours today to get a connection with my SQL Server 2012 database from Visual Studios 2012, I give up.
Setup:
Database: App_Data/GameDB.mdf
DB Location: C:\Users\USERNAME\Documents\Visual Studio 2012\Projects\ProjectRawWar\ProjectRawWar\App_Data\GameDB.mdf
Connection string:
<add name="LocalSqlServer"
connectionString="Data Source=(LocalDB)\v11.0;Initial Catalog=GameDB;Integrated Security=False;"/>
I first tried a SQL Server Compact database, didn't work.
I tried many other connection strings from connectionstrings.com, didn't work.
I tried to put the full path of the database in the connection string, didn't work.
Can someone please help me out of my misery?
Update:
I just followed http://msdn.microsoft.com/en-us/library/aa983322.aspx.
The database is there. I copied the connection string from the wizard right into my webconfig connectionstring, still doesnt work. Why? Where is the logic?
Reading your question I am getting the feeling that you are trying to connect to a database file. While you can do that with Access "Databases" it is not possible with SQL Server databases. The file needs to be mounted or attached to SQL Server first.
Check out this MSDN article for details: http://msdn.microsoft.com/en-us/library/ms190209.aspx#SSMSProcedure
If you're going to disable integrated security, then you need to provide a username and password.
IE:
Server=127.0.0.1;User ID=useridhere;Password=passwordhere;database=dbnamehere
Be sure to make sure the userid and password you specify has access to the database you need. For testing, you can use the 'sa' account, but that's a poor long-term solution for major security reasons.
Ok I fixed it myself.
How I did it:
Delete every .sdf and .mdf file.
Just made following connection strings:
`<add name="DataContext"
connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\GameDB1.mdf;Integrated Security=True"
providerName="System.Data.SqlClient" />
<add name="LocalSqlServer"
connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\GameDB1.mdf;Integrated Security=True"
providerName="System.Data.SqlClient" />`
Visual Studio created my database using my DBContext.
Thanks all for the information.
I have a database on SQL Server 2008. I have an ASP.NET application that uses the Enterprise Library to connect to the database. The configuration to connect to this database currently looks like the following:
<add name="DbConnectionString" connectionString="Server=serverName;Database=DatabaseName;Uid=user.name;Pwd=myPassword;" providerName="System.Data.SqlClient" />
This approach works. I want to move this database to SQL Azure. In the management portal, I have a connection string that looks like the following:
Server=tcp:serverName.database.windows.net,1433;Database=DatabaseName;User ID=user.name#serverName;Password=myPassword;Trusted_Connection=False;Encrypt=True;
How do I format the SQL Azure string so that I can put it in the connectionString value of my configuration setting?
Thank you!
My connection string is a format like:
Password=MyPassword;Persist Security Info=True;User ID=MyUsername;Initial Catalog=MyDatabase;Data Source=n65hf24eep.database.windows.net
I'm trying to connect to my SQL Server 2008 database with ASP.NET MVC 3. Here is my connection string:
<connectionStrings>
<add name="AppConnectionString"
connectionString="Data Source=(local);Initial Catalog=DatabaseName;User Id=UserName;Password=PassWord;"
providerName="System.Data.SqlClient" />
</connectionStrings>
Any idea of what's wrong?
When I try to query something in my DbContext I get this exception:
$exception {"The provider did not return a ProviderManifestToken string."} System.Exception {System.Data.ProviderIncompatibleException}
InnerException {"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)"} System.Exception {System.Data.SqlClient.SqlException}
Could someone help me please?
Thanks
First check if your mssqlserver services are running fine. Just run net start mssqlserver in your command prompt.
Then try changing the connection string Data Source=(local) to Data Source=.
All the above is assuming that you have sql server installed in your local machine.
That error means that either the name of your Data Source in your connectionstring is wrong or that your sql server is not configured to allow remote connections : see here how to fix it.
Can you ping the server?
You can create a new empty text file, rename it to test.udl, double click on it and create your connection string that way. (A dialog will open and you can select provider, server, database etc).
also, have a look at www.connectionstrings.com for example connection strings
There is also the instance to take into account. eg if you use sqlexpress it may be (local)\SQLEXPRESS
Besides (local) try (localhost) or 127.0.0.1 (loopback address - and no place like ;-)
Also a single period will "." resolve to the local machine.
Your connection string and the advice above assumes that you are trying to connect to an unnamed, default instance. If your server instance is named then you need to include that as part of your conn string, like: .\ServerName
More great info can be found at: http://connectionstrings.com
I had a similar problem, and these are the steps that helped me:
1) Your application must have an App.config containing a connectionstring named with the same name as your class that inherited from DbContext. In my case "TestEF_CF.ProductContext".
<add name="TestEF_CF.ProductContext" connectionString="Data Source=localhost;Initial Catalog=ef_cf_test;Integrated Security=True" providerName="System.Data.SqlClient" />
2) The database cannot be created before you start to use it. Just set the Initial Catalogue to the name you want Entity Framework to create when it autocreate the database.
See my stackowerflow question for more information if you need it:
Entity Framework 4.1 Code First Freeze
If you look at the InnerException it's possible that what you actually have is a Login issue.
What I had to do to fix this was, change the account the DefaultAppPool runs as, to NetworkService (go to Advanced Settings and change Process Model, Identity) and then pick an account which has access to your database.
Assuming of course your app is running in IIS using the DefaultAppPool.
I made it NetworkService and granted the NT AUTHORITY\NETWORK SERVICE user access to my existing database.
This then allowed me to connect. My case might be specific but I thought I'd share just in case.
SqlConnection [object name];
[object name] = new SqlConnection("Data Source=Server_address/name;Initial Catalog=myDatabase;Integrated Security=True");
[object name].Open();
Note: The square brackets which is shown should not be putted, only object name have to be placed.
Server_address : Your Computer name.
myDatabase : your Database name.
I have made the remote database backup (MSSQL Server 2005 Express) to the localhost, and I want to connect with that in my app. To do so, I've changed the connection string:
from
Data Source=190.190.200.100;Initial Catalog=myDataBase;User ID=myUsername;Password=myPassword;
to
Data Source=TOMEK\SQLExpress;Database=myDataBase;User ID=myUsername;Password=myPassword;
but the error appears: Format of the initialization
string does not conform to specification starting at index 0
I can login to the Management studio with that login/pass, and also the user name that I login into sql server has role membership db_owner to that database
what's wrong with that connection string ?
Try one of the 2 options.
Data Source=foo\SQLExpress;Initial Catalog=bar;User Id=user;Password=pwd;
or
Server=foo\SQLExpress;Database=bar;User ID=user;Password=pwd;
They're equivalent, but not sure if you can mix/match
Server/Data Source
Database/Initial Catalog
Are you using a hardcoded string, or from a .config file? Does your username or pwd contain any characters that might need escaping in the .config file? i.e. slash, ampersand?
string connstr = #"Server=foo\SQLExpress;Database=bar;User ID=user;Password=pwd;";
SqlConnection conn = new SqlConnection(connstr);
<add name="ConnectionString"
connectionString="Data Source=.\SQLEXPRESS;Database=bar;User ID=user1;Password=&foo;"
providerName="System.Data.SqlClient" />
Maybe try comparing what you are doing to what is found here:
