I am new in Phprunner and cant understand how to calculate in 2 fields, if I am not able to explain please check the below code and the error generated below.
SQL
SELECT ADID,
Date of Booking,
AdCount,
Ad Type,
Company,
Name,
NoChnls,
AdDuration,
TAirTime,
StartDate,
StopDate,
StopDate-StartDate AS DaysRemaining,
Billed,
Received,
Received-Billed AS Balance,
Receivedby
FROM ad booking form
Now when i run this database the below error is generated
Record was NOT added. You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '-Billed, Receivedby) values ('04/18/2011 ', 1, 'Scroll', 'Maptechie', 'Ali AHmed' at line 1
When I run the db with any one of the above like DAYSREMAINING or BALANCE the db runs fine.
