Sql Server 2005
Is there a straightforward way to calculate the number of occurrences in a given date range? Ex.
I have a Vehicle table V joined with VehicleRepairOrder table RO on V.VehicleId = RO.VehicleId.
It's a one-to-many relationship and I need to find the number of vehicles with 3 or more repair orders in any given year (RO.DateOfRO is the field I'm trying to make the date calculations from)
Any input or suggestions would be appreciated.
