      Description

      We do not support ORDER BY within subqueries that are unioned, for example:

      SELECT * FROM
      		 
      ((SELECT a, b FROM t1 ORDER BY b LIMIT 2) sq1
      		 
      UNION ALL
      		 
      (SELECT a, b FROM t2 ORDER BY b LIMIT 2) sq2)
      		 
      ORDER BY 1,2;
