Question

I am creating a method that collects accumulated totals throughout the month. The problem is that there may not be charges for some of the items in a given month so no rows would be returned.

I can see how this would error with no data:

double fuelCost = (double)(from a in db.EquipmentFuelLogs
                           where a.wdEquipmentMainGeneralOID == vehicleKey &&    
                                (monthBeginDate < a.Date1 && a.Date1 < monthEndDate)
                           select a.TotalCost).Sum();

What is the best approach to detect no fuel transactions for that month and set the fuel cost to 0? Just do a try catch? This article spoke of the problem but no solution.

Answer 1

I added a catch to catch the error. I never found a different solution.
