Once you have a connection, you can select it and the Properties window shows you the connection string. The wizard guides you through the basic choices. From those panes, you can right-click on the Data Connections node and select “ Add Connection“. If you’re working in other editions of Visual Studio, open the Server Explorer window. If you are working in Microsoft Visual Web Developer 2010, then you should open the Database Explorer window. First, there is a great website that provides examples for many more connection strings than I have given here. There are a few tips for generating connection strings. Data Source=.\SQLEXPRESS AttachDbFilename=C:\Temp\MyDatabase.mdf Integrated Security=True User Instance=True Note that the database can not also be attached to a running SQL Server instance for this type of connection to succeed, which means you won’t see this database in a tool like SQL Server Management Studio unless you attach to it. This is useful for users that are not administrators on their machines. A user instance opens up a target database file directly in a new instance of SQL Server Express that is running under the context of the current user. The following connection string uses a feature called User Instances. Data Source=.\SQLEXPRESS Initial Catalog=AdventureWorksLT User ID=myuser Password=mypasswordģ.

Obviously this opens up a concern about people seeing this information in the code or in a configuration file (see Connection Strings and Configuration Files). Instead, it uses SQL Server Authentication, which requires a user name and password. The following connection string is the same as the first one, except that it does not use Windows Authentication (note that the Integrated Security property is not specified). Data Source=.\SQLEXPRESS Initial Catalog=AdventureWorksLT Integrated Security=TrueĢ. The following connection string connects to a database (Initial Catalog) on the database server (Data Source) and uses Windows Authentication (Integrated Security=True), which means the user that runs your application must have access to the target database server and database.

To get a full list of properties that you can use, see the documentation for the SqlConnection.ConnectionString Property.ġ. However, there are a few common connection strings that I’d like to describe. There are a lot of properties you can set on your connection string. I’ll talk more about this at the end of this post. Note that some development tools will present you with a dialog box and create the connection string based on your choices. This string specifies that my local SQLEXPRESS instance is the database server, AdventureWorksLT is the database, and my current login should be used to authenticate. The connection string contains a set of properties separated by semicolons. In this example, the SqlConnection object specifies the connection string in the constructor. SqlCommand cmd = new SqlCommand("select count(*) from SalesLT.Address", sqlConn) Ĭonsole.WriteLine("There are rows in the SalesLT.Address table.", Convert.ToInt32(cmd.ExecuteScalar())) New Source=.\SQLEXPRESS Initial Catalog=AdventureWorksLT Integrated Security=True") Here is some basic ADO.NET code that uses a connection string: In this post, we’ll cover the basics, provide some examples, and point to tools that automatically generate connection strings.

Development tools can hide or create this connection string for you, but it helps to know how to create one and what it means. A connection string specifies how to connect to your SQL Server database.

You can develop web or client applications with a retail version of Visual Studio or the free edition, Visual Studio 2010 Express (there is also a new product called Web Matrix that we hope to talk about in future posts). Many people start learning SQL Server, because they want to use a database in application development.
