在SQL查询中平均时间戳

Question

Simple question really....

How do I average timestamps in an SQL query??

The column format is set to TIME

and the values are as follows.

00:01:32
00:02:22
00:02:14
00:01:35
00:01:19

I simply want to add up the minutes and seconds, and calculate the average time spent on a task

So in this instance it would be 542 seconds / 5 tasks for an average of 108.4 seconds or 00:01:48 per task.

It seems so simple yet I cannot for the life of me find any answers. Everything I've found so far uses DATETIME or TIMESTAMP fields. Im simply using TIME.

Answer 1

Assuming MySQL:

SELECT AVG(TIME_TO_SEC(your_column)) AS average_seconds,
SEC_TO_TIME(AVG(TIME_TO_SEC(your_column))) AS average_time
FROM your_table;
