      •  All SqlConnection connection string properties

        • This table shows all connection string properties for the ADO.NET SqlConnection object. Most of the properties are also used in ADO. All properties and descriptions is from msdn.

          Name Default Description
          Application Name   The name of the application, or '.Net SqlClient Data Provider' if no application name is provided.
          AttachDBFilename
          -or-
          extended properties
          -or-
          Initial File Name          		   The name of the primary file, including the full path name, of an attachable database. The database name must be specified with the keyword 'database'.
          Connect Timeout
          -or-
          Connection Timeout          		 15 The length of time (in seconds) to wait for a connection to the server before terminating the attempt and generating an error.
          Connection Lifetime 0 When a connection is returned to the pool, its creation time is compared with the current time, and the connection is destroyed if that time span (in seconds) exceeds the value specified by connection lifetime. Useful in clustered configurations to force load balancing between a running server and a server just brought on-line.
          Connection Reset 'true' Determines whether the database connection is reset when being removed from the pool. Setting to 'false' avoids making an additional server round-trip when obtaining a connection, but the programmer must be aware that the connection state is not being reset.
          Current Language   The SQL Server Language record name.
          Data Source
          -or-
          Server
          -or-
          Address
          -or-
          Addr
          -or-
          Network Address          		   The name or network address of the instance of SQL Server to which to connect.
          Enlist 'true' When true, the pooler automatically enlists the connection in the creation thread's current transaction context.
          Initial Catalog
          -or-
          Database          		   The name of the database.
          Integrated Security
          -or-
          Trusted_Connection          		 'false' Whether the connection is to be a secure connection or not. Recognized values are 'true', 'false', and 'sspi', which is equivalent to 'true'.
          Max Pool Size 100 The maximum number of connections allowed in the pool.
          Min Pool Size 0 The minimum number of connections allowed in the pool.
          Network Library
          -or-
          Net          		 'dbmssocn' The network library used to establish a connection to an instance of SQL Server. Supported values include dbnmpntw (Named Pipes), dbmsrpcn (Multiprotocol), dbmsadsn (Apple Talk), dbmsgnet (VIA), dbmsipcn (Shared Memory) and dbmsspxn (IPX/SPX), and dbmssocn (TCP/IP).
          The corresponding network DLL must be installed on the system to which you connect. If you do not specify a network and you use a local server (for example, "." or "(local)"), shared memory is used.
          Packet Size 8192 Size in bytes of the network packets used to communicate with an instance of SQL Server.
          Password
          -or-
          Pwd          		   The password for the SQL Server account logging on.
          Persist Security Info 'false' When set to 'false', security-sensitive information, such as the password, is not returned as part of the connection if the connection is open or has ever been in an open state. Resetting the connection string resets all connection string values including the password.
          Pooling 'true' When true, the SQLConnection object is drawn from the appropriate pool, or if necessary, is created and added to the appropriate pool.
          User ID   The SQL Server login account.
          Workstation ID the local computer name The name of the workstation connecting to SQL Server.


          Note
          Use ; to separate each property.
          If a name occurs more than once, the value from the last one in the connection string will be used.
          If you are building your connection string in your app using values from user input fields, make sure the user can't change the connection string by inserting an additional property with another value within the user value.

          Equivalents

             (use |DataDirectory| when your database file resides in the data directory)
          Why is the "Database" parameter needed? Answer: If the database was previously attached, SQL Server does not reattach it (it uses the attached database as the default for the connection).
          (the package contains booth the ODBC driver and the OLE DB provider)

        •  Using "User Instance" on a local SQL Server Express instance:
          "Data Source=.\SQLExpress;integrated security=true;attachdbfilename=|DataDirectory|\mydb.mdf;user instance=true;"
          The "User Instance" functionality creates a new SQL Server instance on the fly during connect. This works only on a local SQL Server 2005 instance and only when connecting using windows authentication over local named pipes. The purpose is to be able to create a full rights SQL Server instance to a user with limited administrative rights on the computer. To enable the functionality: sp_configure 'user instances enabled','1' (0 to disable)
          Using SQL Server 2005 Express? Don't miss the server name syntax: SERVERNAME\SQLEXPRESS (Substitute "SERVERNAME" with the name of the computer)
      •  Context Connection - connecting to "self" from within your CLR stored prodedure/function

        •  C#:
          using(SqlConnection connection = new SqlConnection("context connection=true"))
          {
              connection.Open();
              // Use the connection
          }


        •  Visual Basic:
          Using connection as new SqlConnection("context connection=true")
              connection.Open()
              ' Use the connection
          End Using


          The context connection lets you execute Transact-SQL statements in the same context (connection) that your code was invoked in the first place.

        •  When to use SQL Native Client?

          •  .Net applications
            Do not use the SQL Native Client. Use the .NET Framework Data Provider for SQL Server (SqlConnection).
          •  COM applications, all other then .Net applications
            Use the SQL Native Client if you are accessing an SQL Server 2005 and need the new features of SQL Server 2005 such as MARS, encryption, XML data type etc. Continue use your current provider (OLE DB / ODBC through the MDAC package) if you are not connecting to an SQL Server 2005 (that's quite obvious eh..) or if you are connecting to an SQL Server 2005 but are not using any of the new SQL Server 2005 features.

            "Provider=Sybase ASE OLE DB Provider; Data source=myASE"
            Note that you must create a Data Source .IDS file using the Sybase Data Administrator. These .IDS files resemble ODBC DSNs.

               - some reports on problem using the above one, try the following as an alternative -

            "Provider=Sybase.ASEOLEDBProvider;Server Name=myASEserver,5000;Initial Catalog=myDBname;User Id=username;Password=password"
            This one works only from Open Client 12.5 where the server port number feature works,燼llowing fully qualified connection strings to be used without defining燼ny .IDS Data Source files.

            oCon.ConnectionString="my connection string";
