Answer 1

这正是biziclop所说的，但应该有效。

SELECT
  Keyword,
  Nemayeh.Nemayeh
FROM
  (SELECT Keyword.Id,Keyword.Keyword 
   FROM Keyword
   ORDER BY Keyword.Keyword ASC
   LIMIT 10 OFFSET 0) AS tmp

INNER JOIN KeyWord_Nemayeh ON KeyWord_Nemayeh.Id_Keyword = tmp.Id

INNER JOIN Nemayeh ON Nemayeh.Id = KeyWord_Nemayeh.Id_Nemayeh

ORDER BY 1,2 LIMIT 0, 10
