SQL返回包含与主键相关的外键的表的列表

Question

I am trying to query the mySQL database to return a list of tables containing a foreign key associated with a primary key. For example, I have a table containing "reference_number" and other tables containing "reference_number" as a foreign key. How would I query the database to return the list of tables containing "reference_number" as a foreign key? Thanks.

MySQL: How to I find all tables that have foreign keys that reference particular table.column AND have values for those foreign keys?

A possible solution is:

USE information_schema;
SELECT *
FROM
  KEY_COLUMN_USAGE
WHERE
  REFERENCED_TABLE_NAME = 'your_table'
  AND REFERENCED_COLUMN_NAME = 'reference_number';
