常用JDBC連接數據庫方法總結如下： 

一、DB2 

Class.forName("Com.ibm.db2.jdbc.net.DB2Driver"); 

String url="jdbc:db2://dburl:port/DBname" 

cn = DriverManager.getConnection( url, userName, password ); 

二、Microsoft SQLServer(microsoft) 

Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver" ); 

cn = DriverManager.getConnection( "jdbc:microsoft:sqlserver://DBServerIP:1433;databaseName=master", userName, password ); 

三、Sybase(jconn2.jar) 

Class.forName( "com.sybase.jdbc2.jdbc.SybDriver" ); 

cn = DriverManager.getConnection( "jdbc:sybase:Tds:DBServerIP:2638", userName, password); 

四、MySQL(mm.mysql-3.0.2-bin.jar) 

Class.forName( "org.gjt.mm.mysql.Driver" ); 

cn = DriverManager.getConnection( "jdbc:mysql://DBServerIP:3306/myDatabaseName", userName, password ); 

五、PostgreSQL(pgjdbc2.jar) 

Class.forName( "org.postgresql.Driver" ); 

cn = DriverManager.getConnection( "jdbc:postgresql://DBServerIP/myDatabaseName", userName, password ); 

六、Oracle(classes12.jar) 

Class.forName( "oracle.jdbc.driver.OracleDriver" ); 

cn = DriverManager.getConnection( "jdbc:oracle:thin:@MyDbComputerNameOrIP:1521:ORCL", userName, password ); 

七、ODBC 

Class.forName( "sun.jdbc.odbc.JdbcOdbcDriver" ); 

Connection cn = DriverManager.getConnection( "jdbc:odbc:" + sDsn, userName, password );
