postgres 有没有函数可以将时间除以整数？
例如：ERROR: operator does not exist: timestamp with time zone / integer 是带时区的时间戳，我想要 "2013-11-14 07:46:15+03:30"
答案 0 :(得分：0)
我认为问题在于它没有被存储为数字。如果我明白你在问什么，你想要的是自纪元以来的时间，而不是像 01/01/1992 之类的东西。
How to convert date time into unix epoch value in Postgres? 讨论了几种将其转换为纪元的方法，但关键的是 select extract(epoch from ts) from data 或 select date_part('epoch', ts) from data;，其中 data 是您的表，而 {{1} } 是你的时间戳。那么你应该可以除以一个整数。
答案 1 :(得分：0)
我找到了解决这个问题的方法：
SELECT to_timestamp(extract(epoch from DATE)/2) AS date FROM Table
其中 DATE 是带时区的时间戳，Table 是给定的表。 结果的类型是带时区的时间戳。
