DocumentDb错误"交叉分区查询仅支持聚合的'VALUE <AggreateFunc>'"

Question

我很难过.

我将以下SQL查询发送到我的documentDb实例.

{"query":"SELECT SUM(c.clicks), SUM(c.opens), MAX(c._ts), COUNT(c) FROM c WHERE c.clicks > 0"}

我收到以下错误:

这很奇怪,因为我可以通过门户运行SAME EXACT查询并让它返回我正在寻找的数据.

例:

这是怎么回事？

UPDATE

• 我使用的是Microsoft.Azure.DocumentDB客户端库的1.17.0版
• 我正在使用.Net Framework 4.6

这是客户端通过HTTP生成的快照:

{"query":"SELECT SUM(c.clicks), SUM(c.opens), MAX(c._ts), COUNT(c) FROM c WHERE c.clicks > 0"}

Answer 1

这种方法对我有用

SELECT VALUE COUNT(1) FROM telemetry T

Answer 2

我陷入了同样的问题。在我的情况下，将实际查询包装到子查询中解决了这个问题：

SELECT VALUE root
FROM 
(SELECT SUM(c.clicks) as sumclicks, SUM(c.opens) as sumopens, MAX(c._ts) as tsmax, COUNT(c) as count FROM c WHERE c.clicks > 0) as root

Answer 3

对于范围仅限于单个分区键的查询（或者当集合没有分区键定义时），Cosmos DB 支持多个聚合。否则，您需要有一个 VALUE 和一个聚合。

至于同一集合的门户和 SDK 之间的差异，这似乎不正确。您应该让团队通过票证/电子邮件进行调查：askcosmosdb@microsoft.com。
