Question

我使用sequelize作为我的后端ORM。但是当我想要＆＃34;其中＆＃34;使用连接表。协会很好，但我不知道怎么做＆＃34;其中＆＃34;。

这是我的代码：

router.get('/id_presta_struct_unit/:id_presta_struct_unit', (req, res) => {
  models.structures.findAll({
    include: {
      required: false,
      model: models.structures_proposer_prestations,
      where: {
        id_presta_struct_unit: req.params.id_presta_struct_unit
      },
      include: {
        model : models.unites_facturation,
      }
    }
  }).then(data => {
    res.writeHead(200, {'Content-Type': 'application/json; charset=utf-8'});
    res.end(JSON.stringify(data));
  });
});

我收到了这个请求

SELECT * FROM structures AS structures LEFT OUTER JOIN structures_proposer_prestations AS structures_proposer_prestations ON structures。id_structure = structures_proposer_prestations。 id_structure 和structures_proposer_prestations。id_presta_struct_unit =＆＃39; 1＆＃39; LEFT OUTER JOIN unites_facturation AS structures_proposer_prestations.unites_facturation ON {{ 1}}。structures_proposer_prestations = id_unite。structures_proposer_prestations.unites_facturation;

但我想得到

SELECT * FROM id_unite AS structures LEFT OUTER JOIN structures AS structures_proposer_prestations ON structures_proposer_prestations。structures = id_structure。 structures_proposer_prestations LEFT OUTER JOIN id_structure AS unites_facturation ON structures_proposer_prestations.unites_facturation。structures_proposer_prestations = id_unite。structures_proposer_prestations.unites_facturation WHERE {{1 } {。{1}} =＆＃39; 1＆＃39; ;

我不知道该怎么办我找不到有同样问题的帖子

有人能指出我正确的方向吗？

提前谢谢。

编辑：

协会

id_unite

资源模型

structures_proposer_prestations

和structures_employer_ressources的模型

id_presta_struct_unit

如果将数组提供给初始连接的where子句，则可以对连接运行原始查询。

示例：

 models.structures.findAll({
where:[["[structures_proposer_prestations].[id_presta_struct_unit] = " + req.params.id_presta_struct_unit, null]],
    include: {
      required: false,
      model: models.structures_proposer_prestations,
      where: {
        id_presta_struct_unit: req.params.id_presta_struct_unit
      },
      include: {
        model : models.unites_facturation,
      }
    }
  }

数组也可以采用标准对象语法，并由AND组合。我传入的null是for paramaters，所以它绝对可以优化为id作为参数，只是不知道手边的语法。
