특정 열로 데이터베이스 데이터 그룹화

Question

데이터베이스가 있는데 레코드가 있습니다. 나는 ordNR에 의해 모든 레코드를 보여주고 싶습니다. 어떻게 할 수 있습니까? 다음 midn에 의해 처음 ordNR에 의해

SELECT Group_concat(ordnr) ordNR, 
     koden, 
     Group_concat(wish) wish, 
     rnamn, 
     bild, 
     pris, 
     cname, 
     onsktext, 
     restidn 
FROM (SELECT m.ordnr AS ordNR, 
       p.id  AS restidn, 
       t.tabnum AS tabNum, 
       m.wishtext AS onsktext, 
       m.meaoid AS midn, 
       m.ordcode AS koden, 
       w.wish, 
       r.meaname AS rnamn, 
       r.meaimg AS bild, 
       r.meaprice AS pris, 
       k.catname AS cname 
     FROM cats k, 
       meals r, 
       tables t, 
       restaurant p, 
       wishes w, 
       meaorder m 
       JOIN orders c 
       ON c.ordnr 
     WHERE p.id = '3' 
       AND c.tabid = t.tabid 
       AND c.ordstatus = '0' 
       AND m.ordnr = c.ordnr 
       AND m.meaid = r.meaid 
       AND m.wishesid = w.id 
       AND r.catid = k.catid)T 
GROUP BY koden, 
      rnamn, 
      bild, 
      pris, 
      cname 
ORDER BY midn DESC
