我只想首先找到所有

，并将

管理器提交

设置为true，并更新

状态

中存在的任何值

导出输出

请参阅

updatedStatus

和

status

这两种状态都相同。 我能做到吗

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

我不知道如何将

updatedstaus

值设置为

状态

值

---

任何更新 参考：

您的查询应如下所示：

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