无法从 MySQL 中删除行

Question

我有一个表，它不会删除一行。具体来说，当我尝试删除 GEO_SHAPE_ID 超过 150000000 的任何行时，它根本不会从数据库中消失。

我尝试过：

1. SQLyog来删除它。
2. 从表中删除 GEO_SHAPE_ID = 150000042（0 行 做作的）。
3. 解锁表然后 2.

据我所知，bigint 是 auto_increment 的有效候选者。有人知道会发生什么吗？ 每当我执行上述任何操作并刷新表列表时，该行都会重新出现。 你必须帮助我们，博士。我们什么也没有尝试过，我们都没有主意了！

编辑：根据 Daniel Vassallo 的建议：

mysql> SELECT * FROM `GEO_SHAPE` WHERE GEO_SHAPE_ID = 150000042;
Empty set (0.01 sec)

答案：在 MySQL 中发现“检查”和“修复”命令后，我发现了损坏的密钥，因此修复了它们并且它起作用了。

附言。这是表结构和一些示例数据，仅供大家搞笑。

CREATE TABLE `GEO_SHAPE` (
  `GEO_SHAPE_ID` bigint(11) NOT NULL auto_increment,
  `RADIUS` float default '0',
  `LATITUDE` float default '0',

  `PARENT_ID` int(11) default NULL,
  `SHAPE_POLYGON` polygon default NULL,

Answer 1

转到 Sequel Pro 右上角的控制台。右键单击运行失败的命令并将其复制。

将其粘贴到 Sequel Pro 顶部的Query 部分并手动运行。

这将使您能够看到阻止该行被删除的错误并修复它。

Answer 2

刚刚用您的数据尝试过，它按预期工作：

DELETE FROM `GEO_SHAPE` WHERE GEO_SHAPE_ID = 150000042;
-- Query OK, 1 row affected (0.00 sec)

结果：

您尝试过吗：

SELECT * FROM `GEO_SHAPE` WHERE GEO_SHAPE_ID = 150000042;

Answer 3

问题是一个损坏的表。我用“CHECK TABLE GEO_SHAPE;”修复了这个问题然后'修复表GEO_SHAPE；
