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?

Use the .NET Framework Data Provider for SQL Server (SqlConnection). COM applications, all other then .Net applications COM applications, all other then .Net applicationsUse 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 (thats 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. 3 ACCESSODBC标准安全Driver=Microsoft Access Driver (*.mdb); Dbq=C:mydatabase.mdb; Uid=Admin; Pwd=; 工作组Driver=Microsoft Access Driver (*.mdb); Dbq=C:mydatabase.mdb; SystemDB=C:mydatabase.mdw; 独占Driver=Microsoft Access Driver (*.mdb); Dbq=C:mydatabase.mdb; Exclusive=1; Uid=admin; Pwd=OLE DB, OleDbConnection (.NET) 标准安全Provider=Microsoft.Jet.OLEDB.4.0; Data Source=somepathmydb.mdb; User Id=admin; Password=; 工作组 (system database)Provider=Microsoft.Jet.OLEDB.4.0; Data Source=somepathmydb.mdb; Jet OLEDB:System Database=system.mdw; 使用密码Provider=Microsoft.Jet.OLEDB.4.0; Data Source=somepathmydb.mdb; Jet OLEDB:Database Password=MyDbPassword; OracleODBC新版本Driver=Microsoft ODBC for Oracle; Server=OracleServer.world; Uid=Username; Pwd=asdasd; 旧版本Driver=Microsoft ODBC Driver for Oracle; ConnectString=OracleServer.world; Uid=myUsername; Pwd=myPassword; OLE DB, OleDbConnection (.NET) 标准安全Provider=msdaora; Data Source=MyOracleDB; User Id=UserName; Password=asdasd; This ones from Microsoft, the following are from Oracle 标准安全Provider=OraOLEDB.Oracle; Data Source=MyOracleDB; User Id=Username; Password=asdasd; 信任的连接Provider=OraOLEDB.Oracle; Data Source=MyOracleDB; OSAuthent=1; OracleConnection (.NET) 标准Data Source=MyOracleDB; Integrated Security=yes; This one works only with Oracle 8i release 3 or later指定用户名和密码Data Source=MyOracleDB; User Id=username; Password=passwd; Integrated Security=no; This one works only with Oracle 8i release 3 or later定义OracleConnection对象C#:using System.Data.OracleClient; OracleConnection oOracleConn = new OracleConnection(); oOracleConn.ConnectionString = my connection string; oOracleConn.Open();VB.NET:Imports System.Data.OracleClientDim oOracleConn As OracleConnection = New OracleConnection()oOracleConn.ConnectionString = my connection stringoOracleConn.Open()Core Labs OraDirect (.NET) 标准User ID=scott; Password=tiger; Host=ora; Pooling=true; Min Pool Size=0; Max Pool Size=100; Connection Lifetime=0Data Shape 微软数据模型Provider=MSDataShape.1; Persist Security Info=False; Data Provider=MSDAORA; Data Source=orac; user id=username; password=mypw4 MySQLMyODBCMyODBC 2.50 本地数据库Driver=mySQL; Server=localhost; Option=16834; Database=mydatabase; MyODBC 2.50 远程数据库:Driver=mySQL; Server=; Port=3306; Option=131072; Stmt=; Database=my-database; Uid=username; Pwd=password; MyODBC 3.51 本地数据库DRIVER=MySQL ODBC 3.51 Driver; SERVER=localhost; DATABASE=myDatabase; USER=myUsername; PASSWORD=myPassword; OPTION=3; MyODBC 3.51 远程数据库DRIVER=MySQL ODBC 3.51 Driver; SERVER=; PORT=3306; DATABASE=myDatabase; USER=myUsername; PASSWORD=myPassword; OPTION=3; OLE DB, OleDbConnection (.NET) 标准Provider=MySQLProv; Data Source=mydb; User Id=UserName; Password=asdasd; Connector/Net 1.0 (.NET)标准Server=Server; Database=Test; Uid=UserName; Pwd=asdasd; Download the driver at MySQL Developer Zone指定端口Server=Server; Port=1234; Database=Test; Uid=UserName; Pwd=asdasd; Default port is 3306.
