Wouldn't you have to mention unorder once for each variable binding in a query like the following one? FOR $sp IN document("sp.xml")//sp_tuple, $p IN unordered(document("p.xml")//p_tuple[pno = $sp/pno]), $s IN unordered(document("s.xml")//s_tuple[sno = $sp/sno]) RETURN <sp_pair> $s/sname , $p/descrip </sp_pair> SORTBY (sname, descrip) Or am I missing something here?
