下面是mysqltestuser表的ddl:

CREATE TABLE `mysqltestuser` (
`userid` int(11) NOT NULL auto_increment,
`name` varchar(50) default NULL,
`chinesename` varchar(50) default NULL,
`registerdatetime` datetime default NULL,
`jf` decimal(20,2) default NULL,
`description` longtext,
PRIMARY KEY (`userid`)
) ENGINE=InnoDB DEFAULT CHARSET=gb2312;

插入些数据:
INSERT INTO `mysqltestuser` (`userid`, `name`, `chinesename`, `registerdatetime`, `jf`, `description`) VALUES
