在MySQL中遇到错误1701,ERROR 1452和ERROR 1305错误-需要一些专业知识
作者：互联网
这是我制作“第三范式”数据库的第一个真正的突破.我成功地创建了DDL脚本(在继续构建脚本之前,我已将逻辑模型验证为3NF),但是我不确定要解决的错误很多.对于这个特殊的案例,我可能会忍受不住咀嚼,但我不想放弃-这对我来说是一个很大的学习曲线,在我的帮助下,我可以超越它继续前进.
首先,这是我的DDL脚本：

这是逻辑模型(如果有人发现任何关系存在问题,尤其是多对多关系,请告诉我).
如果我提供过多的信息,我深表歉意,但是我认为,如果我提供所有这些信息,对于希望帮助我的人来说,事情将会变得更加容易.我花了3个小时来对DDL脚本进行调整,但是花了这么长时间后,我才意识到我需要一个有更多经验的人来帮助我.我已经向具有数据库行业经验的人展示了该逻辑模型,他们认为该模型符合3NF.进行概念模型和逻辑模型对我来说并不是一件坏事,它正在尝试将逻辑模型转换为工作脚本并成功插入已成为最大障碍的数据(我想为每个表插入至少10条记录).
提前致谢！
解决方法:
您还必须添加此语句
将其添加到转储文件的顶部
SET foreign_key_checks = 0;
这将禁用外键检查,您可以轻松执行转储文件
并在转储文件的底部添加另一条语句以启用外键检查
SET foreign_key_checks = 1;
