Calculate elapsed time

Transact-SQL
1

Hello!
I'm trying to get an sql where I can see the elapsed time(Hours, minutes) for a user that hasn't done any activity. Any suggestions?

I have the following tables

Table test, datareg = the time for the latest activity by a user
image

and the result would be something like this
image

2

hello

elapsed time compared to what point of time?

3

Hello!
to the current time

4

always provide data sample not as an image but as proper DDL and DML

declare @kriss table(loguser varchar(50), datreg datetime)

insert into @kriss
select 'Darth Vader', '2022-10-13 15:43:12'

select loguser , datediff(mi, getdate(),datreg) from @kriss

make sure to read this through

getdate() is the current date and time

select 
     logguser 
   , datediff(minute,datreg,getdate()) as inactivity 
from 
   Test
