Kusto 按计数排序

Question

我是 Kusto/KQL 的新手，但在 T-SQL 方面经验丰富。我正在尝试获取异常列表，按类型对它们进行分组，添加一个计数，然后按该计数降序排列。 在 SQL 中它将是：

SELECT Type, COUNT(Type)
FROM exceptions
GROUP BY Type
ORDER BY COUNT(Type) Desc

除了排序，我什么都搞定了。

exceptions
| summarize count() by type

我不知道如何按聚合排序。我试过 | sort by count() desc、| sort by count() by type desc、| as c | sort by c desc、| extend c = summarize count() by type | sort by c desc

Answer 1

count() 聚合的默认列名称是 count_，因此：

exceptions
| summarize count() by type
| sort by count_ desc

或者，明确命名列：

exceptions
| summarize CountExceptions = count() by type
| sort by CountExceptions desc
