what do you mean? If you have AUTOCOMMIT=0, then every SELECT, INSERT,
UPDATE, DELETE starts a new active transaction.

BEGIN does not start a transaction inside InnoDB; it is the first statement
inside the BEGIN block which starts a new active transaction. BEGIN is just
an instruction to MySQL to group upcoming statements as a single
transaction.

If you mean 'event alerters', MySQL does not implement them.

What does it count?

SET AUTOCOMMIT={0 | 1}

CREATE TABLE, DROP TABLE, etc. form a transaction of their own. You cannot
use ROLLBACK to roll them back.
