Azure Cosmos DB SQL API

Question

I am trying to run this query

    SELECT c.foodGroup,
    c.description,
    ch.amount,
    ch.weightInGrams
    ***--ch.description***
    FROM c
    join ch in c.servings
     where c.id = '21272'

The weightingrams and description are key value pairs in servings . The value weightingrams shows up but the description doesn't show up.

I have tried description and [description] but it throws an error saying that description has been used more than once. What's the way around for this?

This is in reference to food.json as provided by cosmosdb try sql api.

Also providing the json:

Answer 1

I have tried description and [description] but it throws an error saying that decription has been used more than once.

This is due to your name of property decription is duplicate, you can try this sql:

SELECT 
    c.foodGroup,
    c.description,
    ch.amount,
    ch.weightInGrams,
    ch.description as ch_description
FROM c
join ch in c.servings
where c.id = '21272'
