order by timestamp

So I got:

But I need like:

Can somebody please help me?

Answer 1

It is possible to use MOD in WHERE clause.

If timestamp is stored as seconds it could be

... WHERE MOD(timestamp, 300) = 0...

to check if seconds number is divisible by 60*5.

Answer 2

Your code looks like SQL Server. You can check that the timestamp meets your conditions using datetimefromparts() and

select top (100000) [timestamp], [value] as fi500
from X
where timestamp = datetimefromparts(2019, 11, 05,
                                    datepart(hour, timestamp),
                                    (datepart(minute, timestamp) / 5) * 5,
                                    0, 0
                                   )
order by timestamp;
