Question

我遇到Integrity constraint violation: 1452 Cannot add or update a child row:错误；

我认为这与foreign constraint有关。

但是我的SQL看起来正确。

此外，它仅在非本地服务器上发生。

本地主机mysql Ver 8.0.12 for osx10.13 on x86_64 (Homebrew)
服务器mysql Ver 14.14 Distrib 5.7.24, for Linux (x86_64) using EditLine wrapper

我的错误消息如下。

 An exception occurred while executing 'INSERT INTO AcStatus (friendsStr, followersStr, oneFriendsStr, oneFollowersStr, friendsNum, followersNum, oneFriendsNum, oneFollower

     */

    private $stIds;

Answer 1

AcStatus列具有外键约束FK_F7258AEB7F7907，这会导致违反。

您需要检查“相关表”值。它很可能没有在Foreign Table上插入相关数据。

您可以使用SHOW ENGINE INNODB STATUS

检查错误详细信息

完整性约束违反错误仅在服务器上
