How to get all columns' names for all the tables in MySQL?

Question

Is there a fast way of getting all column names from all tables in MySQL, without having to list all the tables?

Answer 1

SELECT * FROM information_schema.columns
WHERE table_schema = DATABASE()
ORDER BY table_name, ordinal_position

Since I don't have enough rep to comment, here's a minor improvement (in my view) over nick rulez's excellent answer: replacing WHERE table_schema = 'your_db' with WHERE table_schema = DATABASE().
