Mysql 选择计数，其中计数 > 0

Question

我正在尝试选择此查询中 nbre > 0 的项目:

SELECT c.id, c.nom, c.photo,
    (SELECT count(*) 
     FROM touist_materiel 
     WHERE cat=c.id AND marque=7 AND actif=1
    ) as nbre
FROM touist_materiel_cat c
INNER JOIN touist_materiel m ON m.cat=c.id 
WHERE nbre > 0 
GROUP BY m.cat 
ORDER BY c.nom

此查询不起作用，如何让“where nbre > 0”起作用？ 谢谢

SELECT tmc.id, tmc.nom, tmc.photo, count(tm.*) AS nbre
  FROM touist_materiel_cat tmc
  INNER JOIN touist_materiel tm
    ON tm.cat=tmc.id 
  WHERE nbre > 0 
    AND tm.marque=7 
    AND tm.actif=1
  GROUP BY tm.cat 
  ORDER BY tmc.nom;
