  1. For a Table:

    SELECT    TABLE_NAME,COLUMN_NAME,CONSTRAINT_NAME, REFERENCED_TABLE_NAME,REFERENCED_COLUMN_NAME FROM   INFORMATION_SCHEMA.KEY_COLUMN_USAGE WHERE   REFERENCED_TABLE_SCHEMA = (SELECT DATABASE()) AND   REFERENCED_TABLE_NAME = '<table>' \G

    For a Column:

    SELECT    TABLE_NAME,COLUMN_NAME,CONSTRAINT_NAME, REFERENCED_TABLE_NAME,REFERENCED_COLUMN_NAME FROM   INFORMATION_SCHEMA.KEY_COLUMN_USAGE WHERE   REFERENCED_TABLE_SCHEMA = (SELECT DATABASE()) AND   REFERENCED_TABLE_NAME = '<table>' AND   REFERENCED_COLUMN_NAME = '<column>' \G

    Basically, change REFERENCED_TABLE_NAME with REFERENCED_COLUMN_NAME in the WHERE clause.
