   Data modification statements made to tables in the
   <code class="literal">
    mysql

        value of
   <a class="link" href="replication-options-binary-log.html#sysvar_binlog_format">
    <code class="literal">
     binlog_format

   ; if this
        value is
   <code class="literal">
    MIXED
   </code>
   , these statements are
        replicated using row-based format. However, statements that
        would normally update this information indirectly—such
   <a class="link" href="grant.html" title="15.7.1.6 GRANT Statement">
    <code class="literal">
     GRANT
    </code>
   </a>
   ,
   <a class="link" href="revoke.html" title="15.7.1.8 REVOKE Statement">
    <code class="literal">
     REVOKE
    </code>
   </a>
   , and statements
        manipulating triggers, stored routines, and views—are
        replicated to replicas using statement-based replication.
