云开发时如何针对多层嵌套数组数据库进行操作，我通过最里层数组的一个唯一字段，如何获取这个数组的内容？

PHIL 2021-11-08 2184 浏览问题模块： API和组件

我有三层嵌套的数组数据库，第一层的一个字段是数组，在这个数组下面的某个字段依然是对象数组，在这个对象数组的某个字段又是一个对象数组。我现在想通过第三层对象数组的某一个键（整个数据库中唯一的）想获取包含这个键值的对象的数据，如何获取呢？即where条件如何写，get获取数据如何写代码？有没有技术大神或者官方的技术官能给予答复，万分感谢

需求：我现在想依据最里层对象中的id 值2300 来改变这个对象中sellout的值为0，如何实现函数代码？
