Oracle

ODBC

新版本

Driver={Microsoft ODBC for Oracle}; Server=myServerAddress; Uid=myUsername;Pwd=myPassword;

旧版本

Driver={Microsoft ODBC Driver for Oracle}; ConnectString=OracleServer.world; Uid=myUsername; Pwd=myPassword;

OLE DB, OleDbConnection (.NET)

标准连接

此连接字符串适用了微软的驱动。

Provider=msdaora;Data Source=MyOracleDB; User Id=myUsername; Password=myPassword;

受信连接

Provider=msdaora; Data Source=MyOracleDB; Persist Security Info=False; Integrated Security=Yes;

标准连接

由Oracle提供的驱动。

Provider=OraOLEDB. Oracle;Data Source=MyOracleDB; User Id=myUsername; Password=myPassword;

受信连接

Provider=OraOLEDB.Oracle;Data Source=MyOracleDB;OSAuthent=1;

Oracle.DataAccess.Client.OracleConnection

标准

Data Source=TORCL;User Id=myUsername; Password=myPassword;

标准安全连接

Data Source=TORCL;Integrated Security=SSPI;

使用ODP.NET而不使用tnsnames.ora

Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=MyHost) (PORT=MyPort)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=MyOracleSID)));
User Id=myUsername;Password=myPassword;

OracleConnection, Oracle Data Provider, ODP.NET.

System.Data.OracleClient.OracleConnection.

标准

用于8i RC3及以后的版本

Data Source=MyOracleDB;Integrated Security=yes;

指定用户名和密码

用于8i RC3及以后的版本

Data Source=MyOracleDB; User Id=myUsername; Password=myPassword; Integrated Security=no;

忽略tnsnames.ora

另一种不需要使用DSN的连接方式

SERVER=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=MyHost) (PORT=MyPort))(CONNECT_DATA=(SERVICE_NAME=MyOracleSID))); uid=myUsername;pwd=myPassword;

使用上面的连接字符串可能会导致Visual Studio报告错误。

如果您在使用中出现了这些问题，请使用下面的这种连接方式。

Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=MyHost)(PORT=MyPort)) (CONNECT_DATA=(SERVICE_NAME=MyOracleSID))); User Id=myUsername;
Password=myPassword;

使用连接池

如果连接池服务程序找不到已经存在的连接池，它将根据连接字符串创建一个新的池。

否则将循环使用池中已存在的连接。

Data Source=myOracleDB; User Id=myUsername; Password=myPassword;Min Pool Size=10;Connection Lifetime=120; Connection Timeout=60;Incr Pool
Size=5;Decr Pool Size=2;

Windows身份验证

Data Source=myOracleDB;User Id=/;

特权连接

使用SYSDBA

Data Source=myOracleDB;User Id=SYS;Password=SYS; DBA Privilege=SYSDBA;

特权连接

使用SYSOPER

Data Source=myOracleDB;User Id=SYS;Password=SYS;DBA Privilege=SYSOPER;

密码过期处理过程

当使用一个连接字符串连接数据库后，出现"密码已过期"的错误时。

请执行OpenWithNewPassword命令来提供新密码。

Data Source=myOracleDB;User Id=myUsername;Password=myPassword; oConn.OpenWithNewPassword(sTheNewPassword);

Proxy验证

Data Source=myOracleDB; User Id=myUsername; Password=myPassword;Proxy User Id=pUserId; Proxy Password=pPassword;
