Question

我有一张表，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，它就不会从数据库中消失。

我试过了：

SQLyog将其删除。
DELETE FROM TABLE WHERE GEO_SHAPE_ID = 150000042 （0行受影响的）。
UNLOCK TABLES 然后2。

据我所知，bigint是auto_increment的有效候选者。任何人都知道什么可以起来？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，Doc。我们已经尝试过了，我们都没有想法！

DJS。

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'check'和'repair'命令后，我发现了损坏的密钥，因此修复了这些密钥并且有效。

PS。这是表格构造和一些仅为咯咯笑的样本数据。

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

  `SHAPE_POLYGON` polygon default NULL,

Answer 1

问题是一张腐败的表格。我用“CHECK TABLE GEO_SHAPE”修正了这个问题;＆＃39;然后＆＃39; REPAIR TABLE GEO_SHAPE;

Answer 2

转到Sequel Pro右上角的Console。右键单击无法运行的命令并将其复制。

将其粘贴到Sequel Pro顶部的Query部分并手动运行。

这将允许您查看阻止删除行的错误并修复它。

Answer 3

只是尝试使用您的数据，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：

你有没有尝试过：

SELECT * FROM `GEO_SHAPE` WHERE GEO_SHAPE_ID = 150000042;

无法从MySQL中删除行
