MySQL：如何找出哪些表引用特定的表？ [英] MySQL: How do I find out which tables reference a specific table?

问题描述

我想删除一个表，但它被一个或多个其他表引用。我怎样才能找出哪个表引用这个表，而不必逐一查看数据库中的每一个表？ pre> select table_name $ b $ from information_schema.KEY_COLUMN_USAGE
where table_schema ='my_database'
and referenced_table_name ='my_table_here';


这个方法可行。

I want to drop a table but it is referenced by one or more other tables. How can I find out which tables are referencing this table without having to look at each of the tables in the database one by one?

解决方案

select table_name
from information_schema.KEY_COLUMN_USAGE
where table_schema = 'my_database'
and referenced_table_name = 'my_table_here';

This works.
