JDBC各种连接数据库方式

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);
