Backendless 3 console

How can I get all photos from console, which don’t have relations
in Backendless 4 I use Advertisement[photos].objectId =null, but in Backendless 3 it doesn’t work


it is the same syntax. Please post the entire screenshot, partial screenshots lack context and make it hard (or in this case impossible) to help you.

I attached 3 photos

  1. Backendless 3, where I get “Invalid where clause null”
  2. Backendless 4 where I get photos with relations (!null)
    3 Backendless 4 where I get photos without relations(null)

Try this:

Advertisement[photos].objectId is null

It works, Thanks a lot

Can you say also, how to make this request in Java?

Please see the documentation:

Thank you
