I need to add hours and minutes. eg 6 hrs and 30 mins I need to get 630
and if minutes is 0 then it has to be just hours like 6. Help appreciated.

Maybe just concatenate them and add a case?

extract(hour from numtodsinterval(to_date(to_char(end_time,'HH24:MI:SS'),'HH24:MI:SS')-to_date(to_char(start_time,'HH24:MI:SS'),'HH24:MI:SS'),'day')) ||

I had tried doing the below that did not work.

case when
extract(minute from numtodsinterval(to_date(to_char(end_time,'HH24:MI:SS'),'HH24:MI:SS')
        -to_date(to_char(start_time,'HH24:MI:SS'),'HH24:MI:SS'),'day')) = 0 then
extract(hour from numtodsinterval(to_date(to_char(end_time,'HH24:MI:SS'),'HH24:MI:SS')
          -to_date(to_char(start_time,'HH24:MI:SS'),'HH24:MI:SS'),'day'))
when extract(minute from numtodsinterval(to_date(to_char(end_time,'HH24:MI:SS'),'HH24:MI:SS')
        -to_date(to_char(start_time,'HH24:MI:SS'),'HH24:MI:SS'),'day')) > 0 then      
extract(hour from numtodsinterval(to_date(to_char(end_time,'HH24:MI:SS'),'HH24:MI:SS')
          -to_date(to_char(start_time,'HH24:MI:SS'),'HH24:MI:SS'),'day'))
extract(minute from numtodsinterval(to_date(to_char(end_time,'HH24:MI:SS'),'HH24:MI:SS')
        -to_date(to_char(start_time,'HH24:MI:SS'),'HH24:MI:SS'),'day')) end diff      

Thanks though

It is still basic formatting and concatenation.

Play around with it a little and see what isn't working with it then adjust.

select 
  trim(extract(hour from numtodsinterval(to_date(to_char(end_time,'HH24:MI:SS'),'HH24:MI:SS')-to_date(to_char(start_time,'HH24:MI:SS'),'HH24:MI:SS'),'day'))) || 
  case when trim(to_char(extract(minute from numtodsinterval(to_date(to_char(end_time,'HH24:MI:SS'),'HH24:MI:SS')-to_date(to_char(start_time,'HH24:MI:SS'),'HH24:MI:SS'),'day')),'00'))  > 0 then 
  trim(to_char(extract(minute from numtodsinterval(to_date(to_char(end_time,'HH24:MI:SS'),'HH24:MI:SS')-to_date(to_char(start_time,'HH24:MI:SS'),'HH24:MI:SS'),'day')),'00'))
