Azure Cosmos DB SQL API
我正在尝试运行这个查询
SELECT c.foodGroup,
c.description,
ch.amount,
ch.weightInGrams
***--ch.description***
FROM c
join ch in c.servings
where c.id = '21272'
weightingrams和description是servings中的键值对。值 weightingrams 出现，但 description 没有出现。
我已经尝试了 description 和 [description]，但它抛出一个错误，指出 description 已被多次使用。有什么办法解决这个问题？
这是参考 cosmosdb 提供的 food.json try sql api.
同时提供 json:

I have tried description and [description] but it throws an error
saying that decription has been used more than once.
这是因为你的名字 属性 decription 重复了，你可以试试这个 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'
我正在尝试运行这个查询
SELECT c.foodGroup,
c.description,
ch.amount,
ch.weightInGrams
***--ch.description***
FROM c
join ch in c.servings
where c.id = '21272'
weightingrams和description是servings中的键值对。值 weightingrams 出现，但 description 没有出现。
我已经尝试了 description 和 [description]，但它抛出一个错误，指出 description 已被多次使用。有什么办法解决这个问题？
这是参考 cosmosdb 提供的 food.json try sql api.

I have tried description and [description] but it throws an error saying that decription has been used more than once.
这是因为你的名字 属性 decription 重复了，你可以试试这个 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'
