[basex-talk] Can't update or delete JSON objects

[E. Wray Johnson]

I have tried XQUERY updates that should work but they don't work.
My technique of storing JSON documents is perhaps not traditional.
I have reduced my example to this simple example.

FRIST CREATE DATABASE WITH ONE DOCUMENT:

db:create('geography', json:parse('{ "code": "USA", "name": "United States
of America", "birth": 1776 }'), '/country')

THEN ADD ANOTHER DOCUMENT:

db:add('geography', json:parse('{ "code": "CAN", "name": "Canada", "birth":
1867 }'), '/country')


   1. How can I update either of these documents using 'code' as the unique
   identifier?
      1. How can I change the 'name' or 'birth'?
      2. How can I add a 'population' number?
      2. How can I delete either of these documents using 'code' as the
   unique identifier?
