Returns TRUE if session is in a multi-statement transaction mode.
OPTION_NOT_AUTOCOMMIT: When autocommit is off, a multi-statement
transaction is implicitly started on the first statement after a
previous transaction has been ended.
OPTION_BEGIN: Regardless of the autocommit status, a multi-statement
transaction can be explicitly started with the statements "START
TRANSACTION", "BEGIN [WORK]", "[COMMIT | ROLLBACK] AND CHAIN", etc.
