使用此配置,表产品具有25’000’000记录

CREATE TABLE `product` (
  `Id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `IdPrice` int(11) unsigned NOT NULL,
  `Description` text NOT NULL,
  PRIMARY KEY (`Id`),
  KEY `Fk_IdPrice_idx` (`IdPrice`),

如何解决？

最佳答案 你可能遇到了一个bug.你可以试试：

>将MySQL升级到最新版本
>将MySQL降级为最新版本
>检查是否可以使用不同操作系统上的数据重现该错误
>获得上述数据后,查看是否可以将其与最小数据集隔离,然后在http://bugs.mysql.com报告错误
>如果该表不必是InnoDB,您可以尝试ALTER TABLE产品ENGINE = MyISAM – 这可能会以失去事务功能和该表中的行级锁定为代价来解决这个问题 – 如果你是这样的话可能会接受小心. MyISAM中的全文支持已有15年历史,在InnoDB中它仍然相当新,所有的错误还没有解决.
