如何使用 alasql 查询 json 文件

问：

亲爱的，我第一次使用 alasql，我需要一些帮助

我的控制台 0：乙 :16 idCatQuestion：未定义

我有一个具有此结构的输出 JSON

var c= [
                          {
                            "0": "1",
                            "1": {
                              "idCatQuestion": "1",
                              "idSousCatQuestion": "1",
                              "designation": "objectifs 1"
                            }
                          },
                          {
                            "0": "2",
                            "1": {
                              "idCatQuestion": "1",
                              "idSousCatQuestion": "2",
                              "designation": "Objectifs 2"
                            }
                          },
                          {
                              "0": "3",
                              "1": {
                                  "idCatQuestion": "2",
                                  "idSousCatQuestion": "3",
                                  "designation": "Objectif 3"
                              }
                          },
           ]

我想用alasql进行查询，这是我的代码

var res = alasql('SELECT idCatQuestion, COUNT(*) AS b FROM ? GROUP BY idCatQuestion',[c]);
console.log(res);
