Question

Is it possible to order by date, and if date is not specified to order by time, and if time is bigger than date then it will be first on the list.
For example we got table –

id    date         time          name

1    18.10.2011    18.10.2011    number    
2    ---------     19.10.2011    number2    
3    ---------     18.10.2011    number3

And it should order something like this –

1    number2
2    number
3    number3

All data is saved in database in time() format, so iif the time and date is equal, it will look at clock. Hope you understood me.

Answer 1

You can attempt to use ORDER BY CASE. This is untested, but should set you on the right track:

ORDER BY CASE
  WHEN date IS NOT NULL AND time < date THEN date
  WHEN time > date OR date IS NULL THEN time
  ELSE time
END

Actually, the ELSE time is probably unnecessary here. The first two cases should cover it.
