database - Does dropping a table in MySQL also drop the indexes?

Question

It's not explicitly mentioned in the documentation (http://dev.mysql.com/doc/refman/6.0/en/drop-table.html). I ask because I just saw a curious database migration in a Rails project where the developer was removing all the indexes before dropping the table, and that seemed unnecessary.

Answer 1

Yes, it does.

However, if you have foreign key constraints such as RESTRICT that ensure referential integrity with other tables, you'll want to drop those keys prior to dropping or truncating a table.
