Question

What I have:

I have a timestamp field with the time that my project started

The user is updating the project with the % complete (1 to 100 not .01 to 1)

I want to insert into an updates table with an estimated completion timestamp.

Basic math:

How to get the full time of the project:

(now() - start timestamp) * (100 / percent complete)

End Time:

start timestamp + full time of the project estimated above

I then need to insert the end time estimated into the table during the insert.

Answer 1

I think i’ve got it.

select timestampadd(second, round(timestampdiff(second, '2012-08-22 22:00:30', now())*(100/33)), '2012-08-22 22:00:30');

that returns:
2012-08-30 17:28:41

the 33 would be the %, and the other timestamps are the start time. Works perfect.
