"""""""""""""""""""""""""""""""""""""""""""""""""""""""""

The recommended way of controlling transactions is via the ~Connection.autocommit attribute. See sqlite3-transaction-control-autocommit.

If Connection.autocommit is set to LEGACY_TRANSACTION_CONTROL (the default), transaction behaviour is controlled using the Connection.isolation_level attribute. Otherwise, !isolation_level has no effect.

If the connection attribute ~Connection.isolation_level is not None, new transactions are implicitly opened before ~Cursor.execute and ~Cursor.executemany executes INSERT, UPDATE, DELETE, or REPLACE statements; for other statements, no implicit transaction handling is performed. Use the ~Connection.commit and ~Connection.rollback methods to respectively commit and roll back pending transactions. You can choose the underlying SQLite transaction behaviour_ — that is, whether and what type of BEGIN statements !sqlite3 implicitly executes – via the ~Connection.isolation_level attribute.

If ~Connection.isolation_level is set to None, no transactions are implicitly opened at all. This leaves the underlying SQLite library in autocommit mode_, but also allows the user to perform their own transaction handling using explicit SQL statements. The underlying SQLite library autocommit mode can be queried using the ~Connection.in_transaction attribute.

The ~Cursor.executescript method implicitly commits any pending transaction before execution of the given SQL script, regardless of the value of ~Connection.isolation_level.

!sqlite3 used to implicitly commit an open transaction before DDL statements. This is no longer the case.

The recommended way of controlling transactions is now via the ~Connection.autocommit attribute.
