How do I see all foreign keys to a table or column?

Question

In MySQL, how do I get a list of all foreign key constraints pointing to a particular table? a particular column? This is the same thing as this Oracle question, but for MyS

Using REFERENCED_TABLE_NAME does not always work and can be a NULL value. The following query can work instead:

select * from INFORMATION_SCHEMA.KEY_COLUMN_USAGE where TABLE_NAME = '';
