javascript - 如何为同一行创建多个where子句？

Question

我想为同一行创建多个Where/AND 子句:这是我的请求正文

"sub_categories":[
        {
            "category_id":2
        },
        {
            "category_id":1
        }

    ]

这是我的 JavaScript 代码

var where = {}
if (subcategories != undefined) {
    subcategories.forEach(async (item) => {
        where['$subcategories.id$'] = item.category_id
    });
}

预期产生的查询:

SELECT * FROM TABLE where sub_categories .category_id = 1 AND sub_categories .category_id = 2

给我的问题:

SELECT * FROM TABLE where sub_categories .category_id = 2 (Last one) 

我需要在代码中添加一些内容才能执行此操作吗？

尝试

var where = {}
if (subcategories != undefined && subcategories.length) {
   where['$and'] = []
    subcategories.forEach((item) => {
        where['$and'].push({
           '$subcategories.id$': item.category_id
        })
    });
}
