04/05/2012 14:24

filtration_end     date ( format - MM/DD/RRRR HH24:MI)

04/05/2012 15:30 changed this to 04/05/2012 13:10

I need to make sure end_filtration is > start_filtration

if :filtration_end < :filtration_start then'Error', 'Filtration End date has to be greater than Filtration Start date.', 'OK');
raise form_trigger_failure;
End if;

Does not work. Need help.

are your fields actually dates or just strings that are human-readable as dates?

if they are dates then your if condition is correct
if they are strings, then convert them to dates when you compare them

if to_date(:filtration_end,'MM/DD/RRRR HH24:MI') < to_date(:filtration_start,'MM/DD/RRRR HH24:MI') then
