<title>Description</title>
<para>Enables or disables an option for the connection. option can
have one of the following values.</para>
<itemizedlist>
<listitem><para>MYSQL_OPTION_MULTI_STATEMENTS_ON Enable multiple-statement support</para></listitem>
<listitem><para>MYSQL_OPTION_MULTI_STATEMENTS_OFF Disable multiple-statement support</para></listitem>
</itemizedlist>
<para>If you enable multiple-statement support, you should
retrieve results from calls to <literal>mysql_query</literal> or
<literal>mysql_real_query</literal> by using a loop that calls
<literal>mysql_next_result</literal> to determine whether there
are more results.</para>
<para>Enabling multiple-statement support with
MYSQL_OPTION_MULTI_STATEMENTS_ON does not have quite the same
effect as enabling it by passing the CLIENT_MULTI_STATEMENTS flag
to <literal>mysql_real_connect</literal>: CLIENT_MULTI_STATEMENTS
also enables CLIENT_MULTI_RESULTS. If you are using the
<literal>CALL SQL</literal> statement in your programs,
multiple-result support must be enabled; this means that
MYSQL_OPTION_MULTI_STATEMENTS_ON by itself is insufficient
to allow the use of CALL.</para>
