Conditional sum in Group By query MSSQL

I have a table OrderDetails with the following schema:

----------------------------------------------------------------
|  OrderId  |  CopyCost  |  FullPrice  |  Price  |  PriceType  |
----------------------------------------------------------------
|  16       |  50        |  100        |  50     |  CopyCost   |
----------------------------------------------------------------
|  16       |  50        |  100        |  100    |  FullPrice  |
----------------------------------------------------------------
|  16       |  50        |  100        |  50     |  CopyCost   |
----------------------------------------------------------------
|  16       |  50        |  100        |  50     |  CopyCost   |
----------------------------------------------------------------

I need a query that will surmise the above table into a new table with the following schema:

----------------------------------------------------------------
|  OrderId  |  ItemCount  |  TotalCopyCost  |  TotalFullPrice  |
----------------------------------------------------------------
|  16       |  4          |  150            |  100             |
----------------------------------------------------------------

Currently I am using a Group By on the Order.Id to the the item count. But I do not know how to conditionally surmise the CopyCost and FullPrice values.

Any help would be much appreciated.

Regards Freddie

You could also try...

select A.OrderID, A.ItemCount,B.TotalCopyCost, C.TotalFullPrice
from (select OrderID, count(*) as ItemCount from orderdetails) as A,
(select OrderID, sum(CopyCost) as TotalCopyCost from orderdetails where PriceType = 'CopyCost') as B,
(select OrderID, sum(FullPrice) as TotalFullPrice from orderdetails where PriceType = 'FullPrice') as C
where A.OrderID = B.OrderID

Try this query

select 
   orderId, 
   count(*) as cnt, 
   sum(if(pricetype='CopyCost', CopyCost, 0)) as totalCopyCost,
   sum(if(pricetype='FullPrice', FullPrice, 0)) as totalFullPrice
from 
   tbl
group by 
   orderId

SQL FIDDLE:

| ORDERID | CNT | TOTALCOPYCOST | TOTALFULLPRICE |
--------------------------------------------------
|      16 |   4 |           150 |            100 |

Try

SELECT OrderId, 
       COUNT(*) ItemCount,
       SUM(CASE WHEN PriceType = 'CopyCost' THEN Price ELSE 0 END) TotalCopyCost,
       SUM(CASE WHEN PriceType = 'FullPrice' THEN Price ELSE 0 END) TotalFullPrice
  FROM OrderDetails
 GROUP BY OrderId

Could you use:

SELECT
  OrderId,
  Count(1) as ItemCount,
  SUM(CASE WHEN PriceType = 'CopyCost' 
        THEN CopyCost ELSE 0 END) AS TotalCopyCost,
  SUM(CASE WHEN PriceType = 'FullPrice' 
        THEN FullPrice ELSE 0 END) AS TotalFullPrice
FROM OrderDetails
GROUP BY OrderId
