     * request. User-supplied arguments to the query should be passed in as
     * separate parameters so that they can be properly escaped to avoid SQL
     * injection attacks.
     *
     * Note that if you need to know how many results were returned, you should do
     * a SELECT COUNT(*) on the temporary table afterwards.
     *
     * @param string $query
     *   A string containing a normal SELECT SQL query.
     * @param array $args
     *   (optional) An array of values to substitute into the query at placeholder
     *   markers.
     * @param array $options
     *   (optional) An associative array of options to control how the query is
     *   run. See the documentation for DatabaseConnection::defaultOptions() for
     *   details.
     *
     * @return string
     *   The name of the temporary table.
