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);
