foreign keys - MySQL: How do I find out which tables reference a specific table?

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?

question from:https://stackoverflow.com/questions/754512/mysql-how-do-i-find-out-which-tables-reference-a-specific-table

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

This works.
