Question

我有一个名为document的表。

引擎innodb

所以我需要插入一些以前从该表中删除的记录。

我删除了主键和auto_increment

执行show create table document检查是否已删除

然后，当我运行insert语句时，我收到错误：

[Err] 1062 - Duplicate entry '492' for key 'PRIMARY'


show create table document

这不仅仅是因为primary key。即使你已经删除了主键;从您的show create table语句中可以清楚地看出，您对列有KEY或UNIQUE KEY约束（如下所示），并且由于您正在获取该重复条目错误导致已经使用{492 1}}现在。

  KEY `IDX_D8698A764ACB6E9C` (`regional_office_id`),
  KEY `IDX_D8698A76979B1AD6` (`company_id`),
  KEY `IDX_D8698A76E93323CB` (`inn`),

当没有主键时，密钥主要的mysql重复条目
