Syntax:
SET sql_log_bin = {0|1}

The sql_log_bin variable controls whether logging to the binary log is
done. The default value is 1 (do logging). To change logging for the
current session, change the session value of this variable. The session
user must have the SUPER privilege to set this variable.

Beginning with MySQL 5.5.5, it is no longer possible to set
@@session.sql_log_bin within a transaction or subquery. (Bug #53437)
