Question

考虑此请求（针对Postgres）

var customers = await database.Customer.findAll({
    attributes: [ 'idcustomer', 'firstname', 'lastname' ],
    include: [
        { 
             model: database.Telephone, as: "Telephones", 
             attributes: [ 'number' ], 
             where: { number: { [database.sequelize.Op.eq]: req.body.telephone } } 
        }
    ],
    where: { [database.sequelize.Op.or]: [
        { firstname: { [database.sequelize.Op.iLike]: req.body.firstname} },
        { lastname: { [database.sequelize.Op.iLike]: req.body.lastname} },
        { email: { [database.sequelize.Op.iLike]: req.body.email } }
    ] }
});

我要实现的是通过名字和姓氏/电子邮件/电话号码查询客户，我们将其称为F，L，E和T。此查询基本上选择所有用户，其中T＆（F | L | E）但是，我要尝试的是（F | L | E | T）。

代码过滤器中的参数where底部位于“客户”之前。参数，因此无法将数字与其余比较分组。有解决方法吗？

生成的SQL：

SELECT 
   "Customer"."idcustomer", "Customer"."firstname", "Customer"."lastname",
   "Telephones"."number" AS "Telephones.number"
FROM "Customer" AS "Customer"
INNER JOIN "Telephone" AS "Telephones" 
    ON "Customer"."idcustomer" = "Telephones"."customer" AND "Telephones"."number" = ''
WHERE
   ("Customer"."firstname" ILIKE '' OR "Customer"."lastname" ILIKE '' OR "Customer"."email" ILIKE '');

Answer 1

您可以使用Sequelize.col（）引用包含的行：

var customers = await database.Customer.findAll({
    attributes: [ 'idcustomer', 'firstname', 'lastname' ],
    include: [
        { 
            model: database.Telephone, 
            as: "Telephones", 
            attributes: [ 'number' ]
        }
    ],
    where: { [database.sequelize.Op.or]: [
        {
          telephone: Sequelize.where(Sequelize.col(`"Telephones".number`), {
            [database.sequelize.Op.eq]: req.body.telephone
          })
        },
        { firstname: { [database.sequelize.Op.iLike]: req.body.firstname} },
        { lastname: { [database.sequelize.Op.iLike]: req.body.lastname} },
        { email: { [database.sequelize.Op.iLike]: req.body.email } }
    ] }
});

Sequelize-嵌套的位置相互覆盖
