我很难过。

我将以下SQL查询发送到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：

<Message>An error has occurred.</Message>

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

发生了什么？

更新

  • 我使用的是Microsoft.Azure.DocumentDB客户端库的1.17.0版本
  • 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"}

3 个答案:

答案 0 :(得分：6)

我陷入了同一个问题。在我的情况下，将实际查询包装到子查询中解决了问题：

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

答案 1 :(得分：5)

这种方法对我有用

SELECT VALUE COUNT(1) FROM telemetry T

答案 2 :(得分：1)

对于作用域为单个分区键的查询（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。

就同一集合的门户网站和SDK之间的区别而言，这似乎不正确。您应该让团队通过票证/电子邮件询问askcosmosdb@microsoft.com。
