firebase - 您可以在复合查询中两次使用whereIn条件吗？

Question

是否可以在Firestore的一个查询中两次使用whereIn？像这样的东西

query.where('venue.id', whereIn: ['11','22','33',]).where('order',whereIn: ['Pending','Preparing']),

Answer 1

不，根据文档:

You can use only one in or array-contains-any clause per query. You can't use both in and array-contains-any in the same query.

另外，如果您有两个 whereIn，它应该引发以下错误:

      if (operator == 'in') {
        assert(!hasIn, "You cannot use 'in' filters more than once."); //this error
        hasIn = true;
      }
