List of Constraints from MySQL Database

Question

How do I get a list of all constraints from a particular database?

Answer 1

Great answer by @Senseful.

I am presenting modified query for those who are only looking for list of constraint names (and not other details/columns):

SELECT DISTINCT(constraint_name) 
FROM information_schema.table_constraints 
WHERE constraint_schema = 'YOUR_DB' 
ORDER BY constraint_name ASC;
