//orcl为你的数据库的SID    
String user="scott";    
String password="tiger";    
Connection conn= DriverManager.getConnection(url,user,password);   
Statement stmt=conn.createStatement   

 

 

二、连接Sql Server7.0/2000数据库

Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();    
String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=pubs";    
//pubs为你的数据库的    
String user="sa";    
String password="";    
Connection conn= DriverManager.getConnection(url,user,password);   
Statement stmt=conn.createStatement   

 

三、连接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);   
Statement stmt=conn.createStatement   

 

四、连接Informix数据库

Class.forName("com.informix.jdbc.IfxDriver").newInstance();    
String url =   
"jdbc:informix-sqli://123.45.67.89:1533/testDB:INFORMIXSERVER=myserver;    
user=testuser;password=testpassword";   
//testDB为你的数据库名    
Connection conn= DriverManager.getConnection(url);   
Statement stmt=conn.createStatement   

 

五、连接Sybase数据库

Class.forName("com.sybase.jdbc.SybDriver").newInstance();    
String url =" jdbc:sybase:Tds:localhost:5007/tsdata";    
//tsdata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);   
Statement stmt=conn.createStatement   

 

六、连接MySQL数据库

Class.forName("org.gjt.mm.mysql.Driver").newInstance();    
String url ="jdbc:mysql://localhost/softforum?    
  
user=soft&password=soft1234&useUnicode=true&characterEncoding=8859_1"    
//testDB为你的数据库名    
Connection conn= DriverManager.getConnection(url);   
Statement stmt=conn.createStatement   

 

七、连接PostgreSQL数据库

Class.forName("org.postgresql.Driver").newInstance();    
String url ="jdbc:postgresql://localhost/soft"   
//soft为你的数据库名    
String user="myuser";    
String password="mypassword";    
Connection conn= DriverManager.getConnection(url,user,password);   
Statement stmt=conn.createStatement
