我只想首先找到所有nodes并将ManagerSubmitted设置为true并更新status在UpdatedStatus中出现的任何值

期望的输出结果

请参见updatedStatus和status都是相同的。我可以这样做

db.collection.update(
            {
                $and : [
                    {
                        $expr:{
                            $ne:["$UpdatedStatus", "$Status"]
                        }
                    },
                    {'ReportingTo': 'b0207296' }
                ]
            }
           , {"$set": {"ManagerSubmitted": true}}, {"multi": true});

我不知道如何将updatedstaus的值设置为status的值

任何更新？

您可以使用addFields并且mongo版本应该是above or equal to 3.4 对于参考：https://docs.mongodb.com/manual/reference/operator/aggregation/addFields/

您的查询应如下：

db.collectionName.aggregate( [
  {
    $addFields: {
      status : "$updatedstaus",     
    }
  }
] )
