  how can i compare the time (oracle package)

  Dec 28, 2012 02:51 PM|LINK

  my input parameter (input_time) is string format input time range from  '0:00' to '24:00', but why i can't compare the input is after 20:00 or not. (Oracle)

  ----------------------------------------------------------------------------------------------

   if(to_date(input_time,'HH24:MI')>=to_date('20:00','HH24:MI')) then     

  variable_a:='1';  

   else    

  variable_a:='2';

  end if; 

   

  when input_time = '22:00',  it fall into else section(variable_a=2) , why?

  You overengineered it.  If the input parameter is a string, and you want to compare it to another string, you don't need the to_date function.

  is it true ? if (i_aa >=‘20:30’) then variable_a :='3' else variable_a :='1' end if ; if i pass '20:45' return 3 is it right ?
