MySql restart之后:#1452-无法添加或更新子行:外键约束失败

问题描述

在MySql重新启动之后，当我尝试更新或插入行时出现此错误:#1452-无法添加或更新子行:外键约束失败.

AFTER MySql restart i get the this error when I try to update or insert a row : #1452 - Cannot add or update a child row: a foreign key constraint fails.

奇怪的是，当我使用phpMyAdmin删除并再次添加键约束时，问题消失了.另外，我只在MAMP中遇到此问题，而在WAMP中则没有，直到现在也没有在任何其他服务器上遇到此问题.我使用MySQL 5.5.9，有人可以为此提供解决方案吗?谢谢，彼得

The strange thing is that when I remove and add the key constraint again with phpMyAdmin the problem is gone. Also this I only have this problem with MAMP, not with WAMP, and also not on any other server until now.I use MySQL 5.5.9 , can anyone give a solution for this ?Thanks,Peter
