In C#, how do I manually build a proper connection string? I have the server name, database name, user name, and password. This is a SQL Server database and .NET 4.0.
I looked at the SQLConnectionStringBuilder and that appears to be what I want but I don't know how to specify the server.
On the SqlConnectionStringBuilder use the DataSource property for the server host name/ip address.
Have a look at the examples at MSDN:
MSDN - SqlConnectionStringBuilder Class
The line of code in question:
builder["Server"] = yourServerName;
Your looking for the DataSource Property
Although you could just set the ConnectionString to something like
Data Source =myServerAddress; Initial Catalog =myDataBase; User Id =myUsername; Password =myPassword;
For alternative connection string for SQL Server 2008 see
http://www.connectionstrings.com/sql-server-2008#p1
You're right : SqlConnectionStringBuilder is the way to go. The DataSource property is the server name. You can find more info about this class on the msdn library. One easy way to figure out what properties you have to set may be to initialize a SqlConnectionStringBuilder using an existing connection string and seeing which properties are used.
For instance, it's likely that you'll use IntialCatalog (the name of the database you want to connect to).
I suggest taking a look at connectionstrings.com.
You can use the SQLConnectionStringBuilder constructor overload that takes a connectionstring as described in the above site.

I am fairly beginner in here, so any help would be much appreciated :)
So, I created a SQL Database and I want to connect EasyTables to it. Apparently the automatic option has been removed and I have to do it manually.
I followed "How can I add a connection string manually" page but it lead me to nothing.
Where should i create the connection string, and what to put in the value field?
Or if there is any tutorials out there for the new way please tell me :)
Thank you a lot
You said you have followed tutorial: How can I add a connection string manually.
The Easy Table connection should like this:
SQL Database Connection String format
Data Source=tcp:{your_SQLServer},{port};Initial Catalog={your_catalogue};User ID={your_username};Password={your_password}
{your_SQLServer} Name of the server, this can be found in the
overview page for your database and is usually in the form of
“server_name.database.windows.net”.
{port} usually 1433.
{your_catalogue} Name of the database.
{your_username} User name to access your database.
{your_password} Password to access your database.
Add the connection string to your Web App
In App Service, you can manage connection strings for your application by using the Configuration option in the menu.
To add a connection string:
Click on the Application settings tab.
Click on [+] New connection string.
You will need to provide Name, Value and Type for your connection
string.
If your are adding a connection string to a SQL Azure database choose
SQLAzure under type.
If your are adding a connection to an Azure Storage account, chose
Custom under type.
NOTE If you are adding a connection string because you are planning on using the Easy API or Easy Table features, then the connection strings used by this features expect the following specific names:
Azure SQL database: MS_TableConnectionString
Azure Storage account: MS_AzureStorageAccountConnectionString
For example, this is my connection string:
When you have configured this, go to Easy table, click Add to add the table name in your Azure SQL database.
You can find that esay table has connected to my Azure SQL database now and we can see the data in the table.
Update:
You should first add the connection string in the configuration followed the format provided for you.
Then go to Easy Table, configure Easy table API:
Choose the 2:
When it done, you can add table in your SQL database, please follow my steps in above.
Note:
Your connection string name must be: MS_TableConnectionString.
Hope this helps.
What is the format of a SqlConnection connection string that is passed in the constructor method? I have run a search engine search online and all I could find so far is examples like:
"Data Source=(local);Initial Catalog=AdventureWorks; Integrated Security=SSPI;"
"User Id=sa;Server=localhost;Initial Catalog=Test;"
The examples raises questions. Since the SQL Server Management Studio (SSMS) program offers a different set of fields during start up in order to connect to a database, I have to ask how does "Server type, "Server name", "Authentication", "User name" and "Password". Also, is "Catalog" another name for a database table?
You should be more specific about what your goal is. This will provide you with better answers.
Catalog is a different name for database, you're connecting to a SQL server and use catalog to specify the database which you want to access.
Server type is either SQL or Windows Authentication
If you're trying to generate a ConnectionString in a string format but don't know how to format the string. The best way is to use the SqlConnectionStringBuilder . After you've set all the variables in the builder use the toString() method to convert it to a string. That way you don't have to worry about how to format your connectionstring.
If you have the string already, or don't need to generate it on the fly you can put it in your web/app.config and use it directly.
A very basic connectionstring that uses SQL authentication looks like this:
"data source=[sqlserver];initial catalog=[database];user id=[username];password=[password];"
I always look at this website for connection string patterns and examples:

I am trying to use nHibernate and Castle and make a connection to one database based on the connection string stored in another database. Is there any way to change the connection string for SessionManager dynamically?
the connectionstring is baked into the sessionfactory. i doubt that you can change it. you could create a lightweight factory to get the connection string or just use ADO.NET directly and then build up the real factory.
Currently I am using SQL Server CE for persisting my data for which I am providing with a .sdf and connection string mentioned in app.config pointing to this .sdf file.
Now I want to provide user with the flexibility to have the data stored in their own SQL Server database if present at there disposal.
Now I am facing the problem of how to change the connection string at runtime if user chooses to uses its own database ?
Or if restrict them to use my predefined .mdf file how to attach that in their SQL Server ?
My recommendation would be to have 2 connection strings in the configuration file (app or web). There is a special section for them intuitively called ConnectionStrings. You can then switch between them based on other settings.
Changing connection strings dynamically is actually pretty easy to do as long as you have a place to store the new settings (ie. web or app config files). If you provide a way for them to enter the server information you can use the ConfigurationManager class to update your app/web.config.
Ado.net typically has parameters on almost any db connection object that allows you to specify the connection string as an arguement. Additionally, there are helper classes that can be used to construct the connection string on the fly like the SqlConnectionStringBuilder or EntityConnectionStringBuilder. I personally love the Entity Framework as it allows you to create the database from the model itself if it does not already exist, provided you already have the connection string.
I have an application that needs to connect to a SQL database, and execute a SQL Agent Job.
The connection string I am trying to access is stored in the registry, which is easily enough pulled out.
This appliction is to be run on multiple computers, and I cannot guarantee the format of this connection string being consistent across these computers. Two that I have pulled out for example are:
Data Source=Server1;Initial Catalog=DB1;Integrated Security=SSPI;
Data Source=Server2;Initial Catalog=DB1;Provider=SQLNCLI.1;Integrated Security=SSPI;Auto Translate=False;
I can use an object of type System.Data.SqlClient.SqlConnection to connect to the database with the first connection string, howevever, I get the following error when I pass the second to it:
keyword not supported: 'provider'
Similarly, I can use the an object of type System.Data.OleDb.OleDbConnection to connect to the database with the second connection string, howevever, I get the following error when I pass the first to it:
An OLEDB Provider was not specified in the ConnectionString'
I can solve this by scanning the string for 'Provider' and doing the connect conditionally, however I can't help but feel that there is a better way of doing this, and handle the connection strings in a more generic fashion.
Does anyone have any suggestions?
The normal way of handling this is storing the ADO.NET provider unique name (separately from the connection string) and using a DB Provider Factory.
Use a SqlConnectionStringBuilder, initialize it with the connection string you find in registry and then read its ConnectionString property, which would normalize the connection string to proper SQL Client syntax.
