sequelize-typescript 获取子查询的属性（使用['属性名']获取属性）

1. raw：true

    book.findAndCountAll({
        attributes:['book.*','person.name'],
        raw:true,
        include:[{
            model:person,
            attributes:['name'],
        }]
    }).then(results => {
        console.log("results.rows[0].name:",results.rows[0]['name']);
    });

2. raw:false

    book.findAndCountAll({
        attributes:['book.*','person.name'],
        include:[{
            model:person,
            attributes:['name'],
        }]
    }).then(results => {
        console.log("results.rows[0].person.name:",results.rows[0]['person.name']);
    });
