没有外键不能创建表errno：150 MYSQL

Question

我有一个具有外键约束的表“供应商”，删除了它，现在我想重新创建一个完全没有外键的表，但是我遇到的经典错误是150，任何想法都可以做。 -创建此表。

Answer 1

In the file that the SQL is dumped in and that you are loading to recreate the database, add SET FOREIGN_KEY_CHECKS = 0 ; at the start and SET FOREIGN_KEY_CHECKS = 1 at the end

Answer 2

It seems that there is an inconsistency there, as creating a table without constraints should be possible at any time. From the Mysql Manual , what you should do is run

SHOW ENGINE INNODB STATUS.

or

SHOW ERRORS

to check the detail of the error you are getting.
