**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();

//sqlserver2005 :   com.microsoft.sqlserver.jdbc.SQLServerDriver

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&useUnicode=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);

**8、access数据库直连用ODBC的**

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver") ;  
String url="jdbc:odbc:Driver=\{MicroSoft Access Driver (\*.mdb)\};DBQ="+application.getRealPath("/Data/ReportDemo.mdb");  
Connection conn = DriverManager.getConnection(url,"","");  
Statement stmtNew=conn.createStatement() ;
