I want to update a set of data.

"records" : [{
 "_id" : ObjectId("5a2e23c750cafa52eaae710d"),
 "createdTime" : "2017-12-11 14:20",
 "jine" : 1500,
 "beizhu":"This is a test"
 },
 {
 "_id" : ObjectId("5a2e23c750cafa52eaae710e"),
 "createdTime" : "2017-12-11 14:25",
 "jine" : 1500,
 "beizhu":"This is a test2"
 }],

For example, I want to update all data with _id 5a2e23c750cafa52eaae710d. if only jine is updated, I understand.

Bill.update({'_id':ObjectId("5a2e23c750cafa52eaae710d")},{$set:{"records.$.jine":200}})

However, it is unclear to update all the data. Please advise. If the key value of the object has only 2 or 3 items, it is easy to say. But what if there are several? If, simply update all the data?
