This isn't always convenient for application developers. To alleviate this

problem, most databases provide an autocommit mode. When autocommit is turned

on and no transaction is active, each SQL query gets wrapped in its own

transaction. In other words, not only does each such query starts a

transaction. In other words, not only does each such query start a

transaction, but the transaction also gets automatically committed or rolled

back, depending on whether the query succeeded.
