JDBC连接各种数据库的方法(摘自ITEYE)

一、JDBC连接DB2

Java代码 

Class.forName("Com.ibm.db2.jdbc.net.DB2Driver");    
String url="jdbc:db2://dburl:port/DBname"    
cn = DriverManager.getConnection( url, sUsr, sPwd );  
Class.forName("Com.ibm.db2.jdbc.net.DB2Driver"); 
String url="jdbc:db2://dburl:port/DBname" 
cn = DriverManager.getConnection( url, sUsr, sPwd );

二、JDBC连接Microsoft SQLServer(microsoft)

Java代码 

Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver" );    
cn = DriverManager.getConnection( "jdbc:microsoft:sqlserver://DBServerIP:1433;databaseName=master", sUsr, sPwd );   
Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver" ); 
cn = DriverManager.getConnection( "jdbc:microsoft:sqlserver://DBServerIP:1433;databaseName=master", sUsr, sPwd ); 

三、JDBC连接Sybase(jconn2.jar)

Java代码 

Class.forName( "com.sybase.jdbc2.jdbc.SybDriver" );    
cn = DriverManager.getConnection( "jdbc:sybase:Tds:DBServerIP:2638", sUsr, sPwd );   
Class.forName( "com.sybase.jdbc2.jdbc.SybDriver" ); 
cn = DriverManager.getConnection( "jdbc:sybase:Tds:DBServerIP:2638", sUsr, sPwd ); 

四、JDBC连接MySQL(mm.mysql-3.0.2-bin.jar)

Java代码 

Class.forName( "org.gjt.mm.mysql.Driver" );    
cn = DriverManager.getConnection( "jdbc:mysql://DBServerIP:3306/myDatabaseName", sUsr, sPwd );   
Class.forName( "org.gjt.mm.mysql.Driver" ); 
cn = DriverManager.getConnection( "jdbc:mysql://DBServerIP:3306/myDatabaseName", sUsr, sPwd ); 

五、JDBC连接PostgreSQL(pgjdbc2.jar)

Java代码 

Class.forName( "org.postgresql.Driver" );    
cn = DriverManager.getConnection( "jdbc:postgresql://DBServerIP/myDatabaseName", sUsr, sPwd );   
Class.forName( "org.postgresql.Driver" ); 
cn = DriverManager.getConnection( "jdbc:postgresql://DBServerIP/myDatabaseName", sUsr, sPwd ); 

六、JDBC连接Oracle(classes12.jar)

Java代码 

Class.forName( "oracle.jdbc.driver.OracleDriver" );    
cn = DriverManager.getConnection( "jdbc:oracle:thin:@MyDbComputerNameOrIP:1521:ORCL", sUsr, sPwd );   
Class.forName( "oracle.jdbc.driver.OracleDriver" ); 
cn = DriverManager.getConnection( "jdbc:oracle:thin:@MyDbComputerNameOrIP:1521:ORCL", sUsr, sPwd ); 

七、JDBC连接ODBC

Java代码 

Class.forName( "sun.jdbc.odbc.JdbcOdbcDriver" );    
Connection cn = DriverManager.getConnection( "jdbc:odbc:" + sDsn, sUsr, sPwd );
