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. Set this
variable to 0 for a session to temporarily disable binary logging while
making changes to the master which you do not want to replicate to the
slave.

As of MySQL 5.5, sql_log_bin can be set as a global or session
variable. Setting sql_log_bin globally is only detected when a new
session is started. Any sessions previously running are not impacted
when setting sql_log_bin globally.

*Warning*: Incorrect use of sql_log_bin with a global scope means any
changes made in an already running session are still being recorded to
the binary log and therefore replicated. Exercise extreme caution using
sql_log_bin with a global scope as the above situation could cause
unexpected results including replication failure.

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