【问题描述】：

能否请您帮我弄清楚 Apache Druid SQL 请求以毫秒为单位获得时间戳的响应。

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]]

【参考方案1】：

您可能可以使用 TIMESTAMP_TO_MILLIS(__time)

欢迎来到 SO。您可以通过反映问题代码的示例来改进您的答案。

有效！ TIMESTAMP_TO_MILLIS(TIME_FLOOR("__time", 'PT24H')) as __time,
