<para>
Returns: A SESAM "result identifier" on success, or
&false; on error.
</para>
<para>
<function>sesam_execimm</function> executes an "immediate"
statement (i.e., a statement like UPDATE, INSERT or DELETE which
returns no result, and has no INPUT or OUTPUT variables).
"select type" queries can not be used with
<function>sesam_execimm</function>. Sets the
<parameter>affected_rows</parameter> value for retrieval by the
<function>sesam_affected_rows</function> function.
</para>
<para>
Note that <function>sesam_query</function> can handle both
"immediate" and "select-type" queries. Use
<function>sesam_execimm</function> only if you know beforehand
what type of statement will be executed. An attempt to use
SELECT type queries with <function>sesam_execimm</function> will
return <literal>$err["sqlstate"] == "42SBW"</literal>.
</para>
<para>
The returned "result identifier" can not be used for retrieving
anything but the <function>sesam_affected_rows</function>; it is
only returned for symmetry with the
<function>sesam_query</function> function.
</para>
