Java程序连接各种数据库的方法

   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();

  //或者Class.forName("com.mysql.jdbc.Driver");

  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() ;
