在 Apache Druid SQL 查询中结合 TIME_FLOOR 和 MILLIS_TO_TIMESTAMP 以获取纪元时间戳

编程问答 2022-05-17

问题描述

能否请您帮我找出 Apache Druid sql 请求以获取以毫秒为单位的时间戳的响应。

SELECT
"c_id",TIME_FLOOR("__time",'PT24H') as __time,SUM(active_conn) as active_conn
FROM "mock_data"
WHERE "__time" BETWEEN TIMESTAMP '2021-03-03 00:00:00' AND TIMESTAMP '2021-03-18 00:00:00' AND "c_id" IN (0,3)  AND "customer_id" = 8526137
GROUP BY 1,2

得到

[["4","2021-03-18T00:00:00.000Z",639477945]]

想要

[["4",1614776400000,639477945]]

解决方法

你或许可以使用 TIMESTAMP_TO_MILLIS(__time)
