  • 0

I’m in ssrs and need to make a chart that compares 2 years of data on a single chart. Since charts in ssrs can only use columns of data for values and not rows I’m forced to write a very long query with lots of unions. I need the 12 months for the horizontal axis and I cant create a new table or any user defined functions. everything has to be in one query.
Is there an easier way to accomplish this task? 

SELECT
'01' AS 'MONTH',
(SELECT COUNT(*) FROM Order JOIN Car ON Order.Car_ID = Car.ID JOIN CarType ON Car.CarType_ID = CarType.ID WHERE @Year = YEAR(Order.OrderDate) AND (@GPI IS NULL OR @GPI = CarType.GPI) AND (@CarType_ID IS NULL OR @CarType_ID = CarType.ID) AND '01' = MONTH(Order.OrderDate)) AS 'Orders1',
(SELECT COUNT(*) FROM Order JOIN Car ON Order.Car_ID = Car.ID JOIN CarType ON Car.CarType_ID = CarType.ID WHERE @Year -1 = YEAR(Order.OrderDate) AND (@GPI IS NULL OR @GPI = CarType.GPI) AND (@CarType_ID IS NULL OR @CarType_ID = CarType.ID) AND '01' = MONTH(Order.OrderDate)) AS 'Orders2'
UNION 
SELECT
'02' AS 'MONTH',
(SELECT COUNT(*) FROM Order JOIN Car ON Order.Car_ID = Car.ID JOIN CarType ON Car.CarType_ID = CarType.ID WHERE @Year = YEAR(Order.OrderDate) AND (@GPI IS NULL OR @GPI = CarType.GPI) AND (@CarType_ID IS NULL OR @CarType_ID = CarType.ID) AND '02' = MONTH(Order.OrderDate)) AS 'Orders1',
(SELECT COUNT(*) FROM Order JOIN Car ON Order.Car_ID = Car.ID JOIN CarType ON Car.CarType_ID = CarType.ID WHERE @Year -1 = YEAR(Order.OrderDate) AND (@GPI IS NULL OR @GPI = CarType.GPI) AND (@CarType_ID IS NULL OR @CarType_ID = CarType.ID) AND '02' = MONTH(Order.OrderDate)) AS 'Orders2'

--It goes on for 12 months

    Try:

    select MONTH(Order.OrderDate) as [MONTH],
       COUNT(CASE WHEN @Year = YEAR(Order.OrderDate) THEN 1 END) as [Orders1],
       COUNT(CASE WHEN @Year-1 = YEAR(Order.OrderDate) THEN 1 END) as [Orders2]
from Order 
JOIN Car ON Order.Car_ID = Car.ID 
JOIN CarType ONCar.CarType_ID = CarType.ID 
WHERE (@GPI IS NULL OR @GPI = CarType.GPI) AND 
      (@CarType_ID IS NULL OR @CarType_ID = CarType.ID)
group by MONTH(Order.OrderDate)
