mysql - 帮助理解和修复mysql错误消息完整性违规: 1452

Question

顺便说一句，我正在使用 zendframework、doctrine 1.2 和 MYSQL

//错误 消息:SQLSTATE[23000]:违反完整性约束:1452 无法添加或更新子行:外键约束失败 (gepm2.Regions，CONSTRAINT Regions_id_Districts_regions_id 外键 (id) 引用 地区 (regions_id))

问题是我将数据存储到区域表中，这些区域的值[ 编号:AR， 名称:测试名称， Country_id:英国]

enter code here

   id:
    type: string(3)

Answer 1

I used a Identifying Relationship instead of a Non-Identifying Relationship

区别在哪里？

这是我的解决方案。问题如上。

$offer = $offerTbl->createRow(array('idcandidate'=>14));
$offer->save();

当我创建一个新行时，我也会从引用的表中给出 FK
