【问题描述】：

我在 Cosmos DB 中有帐户集合。我尝试了不同的查询，但未能通过等效的 SQL 查询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"

收款记录

【解决方案1】：

请使用以下 sql 获取您的文档：

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

Array Contains 可以返回一个布尔值，指示数组是否包含指定的值。

希望对你有帮助。
