`name` varchar(65) NOT NULL default '',
`lastname` varchar(65) NOT NULL default '',
`email` varchar(65) NOT NULL default '',
PRIMARY KEY (`id`)

--
-- Dumping data for table `test_mysql`
--
INSERT INTO `test_mysql` VALUES (1, 'Billly', 'Blueton', 'bb5@phpeasystep.com');
INSERT INTO `test_mysql` VALUES (2, 'Jame', 'Campbell', 'jame@somewhere.com');
INSERT INTO `test_mysql` VALUES (3, 'Mark', 'Jackson', 'mark@phpeasystep.com');
INSERT INTO `test_mysql` VALUES (4, 'Linda', 'Travor', 'lin65@phpeasystep.com');
INSERT INTO `test_mysql` VALUES (5, 'Joey', 'Ford', 'fordloi@somewhere.com');
INSERT INTO `test_mysql` VALUES (6, 'Sidney', 'Gibson', 'gibson@phpeasystep.com');
