JDBC连接常用数据库

1、Oracle8/8i/9i数据库（thin模式） 


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

 String url="jdbc:oracle:thin:@localhost:1521:orcl"; 

 //orcl为数据库的SID 

 String user="test"; 

 String password="test"; 

 Connection conn= DriverManager.getConnection(url,user,password); 


 2、DB2数据库 


 Class.forName("com.ibm.db2.jdbc.app.DB2Driver ").newInstance(); 

 String url="jdbc:db2://localhost:5000/sample"; 

 //sample为你的数据库名 

 String user="admin"; 

 String password=""; 

 Connection conn= DriverManager.getConnection(url,user,password); 


 3、Sql Server7.0/2000数据库 


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

 String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=mydb"; 

 //mydb为数据库 

 String user="sa"; 

 String password=""; 

 Connection conn= DriverManager.getConnection(url,user,password); 


 4、Sybase数据库 


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

 String url =" jdbc:sybase:Tds:localhost:5007/myDB"; 

 //myDB为你的数据库名 

 Properties sysProps = System.getProperties(); 

 SysProps.put("user","userid"); 

 SysProps.put("password","user_password"); 

 Connection conn= DriverManager.getConnection(url, SysProps); 


 5、Informix数据库 


 Class.forName("com.informix.jdbc.IfxDriver").newInstance(); 

 String url = 

 "jdbc:informix-sqli://123.45.67.89:1533/myDB:INFORMIXSERVER=myserver; 

 user=testuser;password=testpassword"; 

 //myDB为数据库名 

 Connection conn= DriverManager.getConnection(url); 


 6、MySQL数据库 


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

 String url ="jdbc:mysql://localhost/myDB?user=soft&password=soft1234&useUnicod 

 e=true&characterEncoding=8859_1" 

 //myDB为数据库名 

 Connection conn= DriverManager.getConnection(url); 


 7、PostgreSQL数据库 


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

 String url ="jdbc:postgresql://localhost/myDB" 

 //myDB为数据库名 

 String user="myuser"; 

 String password="mypassword"; 

 Connection conn= DriverManager.getConnection(url,user,password);
