Firebase query filter(equalTo) in Node

[hitech....@gmail.com]

I need problem in querying for equalTo 

var modellist =admin.database().ref("computer_model");

 modellist.orderByChild("Model number").equalTo("ABC").on('child_added', function(snapshot) {

         var val =snapshot.val().Des;

         

        

    });

I am getting blank in response ,even i have data entry in DB for ABC in Model number

Please suggest.

Did you try to use the "once" call:
[your query].once('value', snap=>{ ...your code...})
?

First things first, you aren’t capturing any errors or logging anything in your success callback. Most likely, an error is occurring.

Try something like:

modellist....on('child_added', snapshot => console.log(snapshot.key), error => console.error(error));

If that’s not getting invoked, then you’ll need to include a more complete repro of the problem.
