[急]在导入decimal时为什么会是负数(-8446744056209541515)
create database if not exists `mo`;

USE `mo`;

/*数据表 `date` 的表结构*/

DROP TABLE IF EXISTS `date`;

CREATE TABLE `date` (
`ID` int(10) unsigned NOT NULL auto_increment,
`Date` date NOT NULL default '0000-00-00 ',
`NewDate` timestamp(14) NOT NULL,
`Str` decimal(45,0) NOT NULL default '345 ',
PRIMARY KEY (`ID`)
) TYPE=MyISAM;

/*数据表 `date` 的数据*/

insert into `date` values

(12, '0000-00-00 ',20070402112232,10000000017500020102),

(11, '0000-00-00 ',20070325032406,10000000017500010101),

(14, '0000-00-00 ',00000000000000,10000000017500010101),

(15, '0000-00-00 ',00000000000000,10000000017500010101),

(16, '0000-00-00 ',00000000000000,10000000017500010101);

[解决办法]
超出Decimal能表达的数值范围了！
