Mysql 我需要选择此条件的位置

我在MySQL中有两个表

1.表格-答案具有属性和值

    Id_Answer      Id_Form      Result                       Total      Average
-------------------------------------------------------------------------------
      13              1  ["2","3","1","3","1","1","2","3"]     16         2.00
      15              1  ["2","2","1","3","0","2","1","0"]     11         1.38

       Id_Criterion .    Id_Form .   Topic           Min .    Max .    Detail
   -------------------------------------------------------------------------------------------
           1                1       Good person       1.5     2         You is a Good person               
           2                1       Bad person         0     1.4         You is a bad

2.表-标准具有属性和值

    Id_Answer      Id_Form      Result                       Total      Average
-------------------------------------------------------------------------------
      13              1  ["2","3","1","3","1","1","2","3"]     16         2.00
      15              1  ["2","2","1","3","0","2","1","0"]     11         1.38

       Id_Criterion .    Id_Form .   Topic           Min .    Max .    Detail
   -------------------------------------------------------------------------------------------
           1                1       Good person       1.5     2         You is a Good person               
           2                1       Bad person         0     1.4         You is a bad

我需要获取criteion.Topic，criteion.Mix，criteion.Min，criteion.Max，criteion.Detail

到，我将使用Answer.Average在criteria.Min和criteria.Max和Answer.Id\u Form=criteria.Id\u Form中进行比较

如何为此创建查询？

查询

select b.Topic, b.Min, b.Max, b.Detail
from Answer a
inner join Criterion b 
on a.Id_Form = b.Id_Form and a.Average between b.Min and b.Max

询问

将其应用于CodeIgniter alsoHi。再见。看见
