mongo db document data

{
    "_id": ObjectId("5589044a7019e802d3e9dbc5"),
    "sessionId": LUUID("f49d4280-ced0-9246-a3c9-a63e68e1ed45"),
    "teamId": LUUID("6ef7d1a8-f842-a54c-bd8c-daf6481f9cfc"),
    "variableId": LUUID("59d1b512-eee2-6c4b-a5b5-dda546872f55"),
    "values": {
        "725400": 691.0000000000000000,
        "725760": 686.0000000000000000,
        "726120": 683.0000000000000000,
        "726480": 681.0000000000000000,
        "726840": 679.0000000000000000,
        "727200": 678.0000000000000000,
        "727560": 677.0000000000000000,
        "727920": 676.0000000000000000
    },
    "variableType": 2,
    "isSet": false,
    "teamNumber": 2,
    "simPageIds": []
}

만약 values.727920을 제거하고 싶다면

db.collectionName.updateMany({},{“$unset":{"values.727920”:1}})
