SQL Server .NET Data Provider
System.Data.SqlClient
The SQL Server .NET Data Provide allows you to connect to a Microsoft SQL Server 7.0 or 2000 database. For Microsoft SQL Server 6.5 or earlier, use the OLE DB .NET Data Provider with the "SQL Server OLE DB Provider" (SQLOLEDB).
Note: The SQL Server .NET Data Provider knows which data provider it is. Hence the "provider=" part of the connection string is not needed.
Using C#:
using System.Data.SqlClient;...SqlConnection oSQLConn = new SqlConnection();oSQLConn.ConnectionString = "Data Source=(local);" + "Initial Catalog=myDatabaseName;" + "Integrated Security=SSPI";oSQLConn.Open();Using VB.NET:
Imports System.Data.SqlClient...Dim oSQLConn As SqlConnection = New SqlConnection()oSQLConn.ConnectionString = "Data Source=(local);" & _ "Initial Catalog=myDatabaseName;" & _ "Integrated Security=SSPI"oSQLConn.Open()If connection to a remote server (via IP address):
oSQLConn.ConnectionString = "Network Library=DBMSSOCN;" & _ "Data Source=xxx.xxx.xxx.xxx,1433;" & _ "Initial Catalog=myDatabaseName;" & _ "User ID=myUsername;" & _ "Pas sword=myPassword"Where:
- "Network Library=DBMSSOCN" tells SqlConnection to use TCP/IP Q238949
- xxx.xxx.xxx.xxx is an IP address.
- 1433 is the default port number for SQL Server. Q269882 and Q287932
- You can also add "Encrypt=yes" for encryption
For more information, see: SqlConnection Class, Q308656, and .NET Data Providers
Note: Microsoft SQLXML Managed Classes exposes the functionality of SQLXML inside the Microsoft .NET Framework.
