morning daily and night calculation

Hi
please have a look to my query
$result=mysql_query( "SELECT a.hr, 
      SUM(case when b.pulse_channel = 1 then b.unit_qty else 0 end) as name1,
      SUM(case when b.pulse_channel = 2 then b.unit_qty else 0 end) as name2,
      SUM(case when b.pulse_channel = 3 then b.unit_qty else 0 end) as name3,
      SUM(case when b.pulse_channel = 4 then b.unit_qty else 0 end) as name4,
      SUM(b.unit_qty) as Total
from (
	select 0  as hr 
	union select 1
	union select 2 
	union select 3
	union select 4 
	union select 5 
	union select 6
	union select 7

	union select 19
	union select 20
	union select 21
	union select 22
	union select 23) a 
left join count_transactions b on a.hr = Hour(b.tran_date)
WHERE DATE(b.tran_date) BETWEEN '$dateb' AND '$dateb' AND unit_serial=$netw
GROUP BY a.hr" ) or die("SELECT Error: ".mysql_error());

change the "a.hr" in the select to:

case when a.hr between 0 and 6 then 'morning'
        when a.hr between 7 and 19 then 'daily'
        when a.hr between 20 and 23 then 'night'
end as part_of_day

Also change it in the group by, except without the "as part_of_day" of course.
