下面是你可以在 Druid 上尝试进行查询的一些实例供你测试：

对时间进行查询

SELECT FLOOR(__time to HOUR) AS HourTime, SUM(deleted) AS LinesDeletedFROM wikipedia WHERE "__time" BETWEEN TIMESTAMP '2015-09-12 00:00:00' AND TIMESTAMP '2015-09-13 00:00:00'GROUP BY 1

复制代码

基本的 group by

SELECT channel, page, SUM(added)FROM wikipedia WHERE "__time" BETWEEN TIMESTAMP '2015-09-12 00:00:00' AND TIMESTAMP '2015-09-13 00:00:00'GROUP BY channel, pageORDER BY SUM(added) DESC
