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&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);
