Question

Hi all oracle gurus
I am trying to insert a value which is difference between two dates, for that reason i am doing (" rec_jag_promos.end_date -rec_jag_promos.start_date") inside my insert statement.
but it is not working. my plsql code is running but not giving me any o/p.
Here what i am trying to do is i want to insert DAYS value into my table which is between start date and end date.
........its not working . please guide me or correct me.
Below is part of my querry ........
Thanks
