azure-cosmosdb - 嵌套对象的 Cosmos DB SQL 查询

Question

我在 Cosmos DB 中有帐户集合。我尝试了不同的查询，但失败了等效的 SQL 查询以仅获取已选择订阅的帐户。

我试过这个查询但失败了

SELECT     *
FROM account a
JOIN s IN c.subscriptions
WHERE s.id = "e5969a3c-2729-cb3c-a01b-2e62e0473646"

账户收款记录

Answer 1

请使用下面的 sql 来获取您的文件:

SELECT * FROM c
where ARRAY_CONTAINS(c.subscriptions,{"id": "e5969a3c-2729-cb3c-a01b-2e62e0473646"},true)

Array Contains可以返回一个 bool 值，指示数组是否包含指定的值。
希望对你有帮助。
