Search through all the records in firebase

[SUBRAMANIYA BHARATHI KANDASAMY]

Hi all,

I have a problem in firebase. the structure of my firebase app is in the screenshot added. What I need to do is to enter user data and search through all the record s and checks whether the entered data is already present or not.  If present update the record with entered data if it is not present then create a new record with the entered data. Kindly help. i am really stuck.

That's normally what id's are for, so you can determine identity without looking at every property.

But if you really need to do this you could create a string hash of the key value pairs, replace any unsupported characters (see fb docs) and create a node for storing the link between hash and id. Total hash would be need to be less than 768 bytes, so you might need to use a checksum if data too big.

So if you had:

+ things

    + key123

        + name: 'bob'

        + age: 12

        + color: 'blue'

    + key456

        + name: 'jill'

        + age: 14

        + color: 'red'

Then you'd also have:

+ lookup

    + name:bob;age:12;color:blue: key123

    + name:jill;age:14:color:red: key 456
