javascript - Update based on Timestamp in Firebase -


i'm having firebase db follows:

{   "page_id": {     "user_1": {       "messages": {         "1502774604": {           "timestamp": 1502774604,           "user": false,           "content": "hi"         },         "1502774613": {           "timestamp": 1502774613,           "user": false,           "content": "hello"         },         "1502791814": {           "timestamp": 1502791814,           "user": false,           "content": "how you"         }       }     }   } }

i want set 'user' field 'true' timestamp less '1502791814'. possible in firebase?

the sql same

update messages set user = true timestamp <= 1502791814

ps: i'm using javascript client

please consider doing following:

firebase.database().ref('page_id/user1/messages').orderbychild('timestamp').endat(1502791814)    .on('value',function(snap){     //now snap array of nodes wanted     //each node can reached using following     snap.foreach(function(eachsnap){     //complete here update stuff      });  });

hope works!
