Question

I’m trying to do something like below (I’ve simplified the problem, to try and solve this individual part).

PRINT DATEADD(week, 0.2,  GETDATE())

Which I realise will not work due to the number parameter of dateadd is truncated to an int.

I’m trying to come up with a way of converting 0.2 to a number of hours and then being able to use something like (I’m ok with it being as accurate to the hour).

PRINT DATEADD(hour, X,  GETDATE())

Any ideas how to get started? I’m finding it tricky to find anything to get a decimal representation of one datepart in another datepart.

It’s got to be a set based query for performance.

In theory I’ve got to make it so decimal years can be used as well, but I’ll come to that as a seperate problem…

Answer 1

1 week = 7 days = 168 hours = 10080 minutes

0.2 weeks = 2016 minutes

PRINT DATEADD(minute, 2016, GETDATE())

To get this to work for years, you could write a User Defined Function where you can input a decimal of years, and then this is multiplied for minutes, and run DATEADD using minutes
