如何使用格式（HH：mm：ss）在MySQL查询中减去时间

Question

timestart = 16:46:33

timeend = 16:48:22

预期结果= 00:01:49

我的查询：

Select timestart , timeend, (timeend - timestart) as rangetime from time;

检查MySQL TIMEDIFF函数。

尝试这个：

SELECT timestart, timeend, TIMEDIFF(timeend, timestart) AS rangetime 
FROM time;

Answer 2

尝试使用SubTime

Select timestart , timeend, SUBTIME(timestart ,timeend) As rangetime from time;
