ADO.net 中数据库连接方式(微软提供)
微软提供了以下四种数据库连接方式:
System.Data.SqlClient.SqlConnection
常用的一些连接字符串(C#代码):
SqlConnection conn = new SqlConnection("Server=(local);Integrated Security=SSPI;database=Pubs"); SqlConnection conn = new SqlConnection("server=(local)\\NetSDK;database=pubs;Integrated Security=SSPI"); SqlConnection conn = new SqlConnection( "Data Source=localhost;Integrated Security=SSPI;Initial Catalog=Northwind;"); SqlConnection conn = new SqlConnection( " data source=(local);initial catalog=xr;integrated security=SSPI; persist security info=False;workstation id=XURUI;packet size=4096; "); SqlConnection myConn = new System.Data.SqlClient.SqlConnection("Persist Security Info=False;Integrated Security=SSPI;database=northwind;server=mySQLServer"); SqlConnection conn = new SqlConnection( " uid=sa;pwd=passwords;initial catalog=pubs;data source=127.0.0.1;Connect Timeout=900");
OleDbConnection conn = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\MyWeb\81\05\GrocerToGo.mdb"); OleDbConnection conn = new OleDbConnection( @"Provider=Microsoft.Jet.OLEDB.4.0;Password=; User ID=Admin;Data Source=grocertogo.mdb;"); OleDbConnection conn = new OleDbConnection( "Provider=MSDAORA; Data Source=ORACLE8i7;Persist Security Info=False;Integrated Security=yes"); OleDbConnection conn = new OleDbConnection( "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=c:\bin\LocalAccess40.mdb"); OleDbConnection conn = new OleDbConnection( "Provider=SQLOLEDB;Data Source=MySQLServer;Integrated Security=SSPI");更多字符串连接说明请看MSDN:
OracleConnection myConn = new System.Data.OracleClient.OracleConnection( "Data Source=Oracle8i;Integrated Security=yes");更多字符串连接说明请看MSDN:
OdbcConnection conn = new OdbcConnection( "Driver={SQL Server};Server=MyServer;Trusted_Connection=yes;Database=Northwind;"); OdbcConnection conn = new OdbcConnection( "Driver={Microsoft ODBC for Oracle};Server=ORACLE8i7; Persist Security Info=False;Trusted_Connection=yes"); OdbcConnection conn = new OdbcConnection( "Driver={Microsoft Access Driver (*.mdb)};DBQ=c:\bin\nwind.mdb"); OdbcConnection conn = new OdbcConnection( "Driver={Microsoft Excel Driver (*.xls)};DBQ=c:\bin\book1.xls"); OdbcConnection conn = new OdbcConnection( "Driver={Microsoft Text Driver (*.txt; *.csv)};DBQ=c:\bin"); OdbcConnection conn = new OdbcConnection("DSN=dsnname");
DB2Connection myConn = new IBM.Data.DB2.DB2Connection( "DATABASE = SAMPLE;UID=Connection Pooling; PWD= ;"); DB2Connection myConn = new IBM.Data.DB2.DB2Connection("DATABASE = SAMPLE"); BdpConnection myConn = new Borland.Data.Provider.BdpConnection("assembly=Borl and.Data.Mssql,Version=1.1.0.0,Culture=neutral,PublicKeyToken=91d62ebb5b0d1b1b;ve ndorclient=sqloledb.dll;osauthentication=False;database= ;usernam e= ;hostname= ;password= ;provider=MSSQL"); BdpConnection myConn = new Borland.Data.Provider.BdpConnection("assembly=Borl and.Data.Db2,Version=1.1.0.0,Culture=neutral,PublicKeyToken=91d62ebb5b0d1b1b;ve ndorclient=db2cli.dll;database= ;username= ; password= ;provider=DB2");
