A MySQL lock refers to a lock flag connected to a table. The main use of MySQL locks is in user sessions to prevent other user sessions from accessing the table during an active session. A specific MySQL session can only access its locks and not locks associated with other clients.
Once a table is locked in a particular session, other sessions cannot read or write to the table unless the lock from the session is released. Therefore, all other sessions are in waiting mode until the lock is released.

This short guide will show you how to show available locks using the show process list command.

Let’s start with different examples to see how we can truncate the file size.
