问题：
Azure Cosmos DB SQL API
司寇正志
我正在尝试运行此查询
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，是服务中的键值对。值＜code＞weightingrams不显示。
我已经尝试了< code>description和< code>[description]，但是它抛出一个错误，指出< code>description已经使用了多次。这有什么办法呢？
这是参考了由宇宙数据库提供的美食.json尝试sql api。
还提供json：

我已经尝试了description和[description]，但它抛出了一个错误，说明已经使用了多次。
这是因为您的属性< code > description 名称重复，您可以尝试以下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'
