+unbuffered_row($type)
+=====
+
+This function returns a single result row without prefetching the whole result in memory as row() does.
+If your query has more than one row, it returns the current row and moves the internal data pointer ahead.
+The result is returned as $type could be 'object' (default) or 'array' that will return an associative array.
