SQl for This exampple:-


CREATE TABLE `contacts` (
  `id` int(10) NOT NULL auto_increment,
  `FirstName` varchar(200) NOT NULL,
  `LastName` varchar(200) NOT NULL,
  `PhoneNumber` varchar(200) NOT NULL,
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=6 ;

–
– Dumping data for table `contacts`
– 

INSERT INTO `contacts` (`id`, `FirstName`, `LastName`, `PhoneNumber`) VALUES (3, ‘Inder’, ‘Singh’, ‘98726-82279′),
(5, ‘Inderweb’, ‘India’, ‘98726-82279′);
