Why is my sum function not working properly?
I am trying to do a simple sum on the "Booking_Factor" column(int) and it is not summing at all as if nothing , the values are the same, any idea? Thank You.
SELECT distinct

Define in simple English what you wish to sum Booking_Factor by. RES.Description? Available_Date_ID?
Then eyeballeth all of the columns in your GROUP BY clause, especially Start_Time and End_Time. Are they unique? If yes, that kinda defeats the purpose of doing the SUM, and you'll have to remove those columns and possibly others to get the correct sum amount.
