Knex Js returns 与原始 SQL 不同的输出

Question

我有两个 table。一个是类别 table，另一个是带有类别外键的项目 table（一个类别可以有多个项目）

我正在尝试公开以下代码中的所有项目

router.route('/projects')
  .get(function(req,res){
    //knex('projects').select(['projects.id','projects.name','projects.category_id','categories.name']).innerJoin('categories','projects.category_id','categories.id')
    knex.from('projects').innerJoin('categories','projects.category_id','categories.id')
    .then(function(collection){

      console.log(collection);
      res.json({
        error:false,
        data: collection
      })
    })
    .catch(function(err){
      res.json({
        error:true,
        data:{
          message:err.message
        }
      })
    })
  })

两个 knex 语句 return 几乎类似于下面的截断输出

{
  "error": false,
  "data": [
    {
      "id": 1,
      "name": "Music",
      "category_id": 1,
      "created_at": 1458126413858
    },
    {
      "id": 2,
      "name": "Science",
      "category_id": 2,
      "created_at": 1458126413858
    }
  ]
}

然而，原始 SQL 似乎是正确的

select * from "projects" inner join "categories" on "projects"."category_id" = "categories"."id"

或

select "projects"."id", "projects"."name", "projects"."category_id", "categories"."name" from "projects" inner join "categories" on "projects"."category_id" = "categories"."id"

运行以上分别在 sqlite 上的语句似乎 return 整个 table 结果

knex 语句哪里出错了？

供参考，这是架构

项目table

var table = (table) => {
  table.increments().primary();
  table.string('name');
  table.integer('category_id').references('categories.id');
  table.timestamp('created_at').defaultTo(Date.now());
}

类别table

var table = (table) => {
  table.increments().primary();
  table.string('name');
  table.timestamp('created_at').defaultTo(Date.now());
}

Answer 1

通过使用如下列名称的别名解决了这个问题

knex('projects').select(['projects.id as projectId','projects.name as projectName','projects.category_id','categories.name as categoryName']).innerJoin('categories','projects.category_id','categories.id')

Knex Js returns a different output from raw SQL

sqlite

node.js

express
