Question : SQL server 2008 query with grouping

I am working on a report in SQL server 2008 using the report desinger and need to do some unique grouping.

Here is my current select statement that works great except for the grouping.

1:
2:
3:
4:
5:
6:
7:
8:
9:
10:
11:
12:
13:
14:
15:
16:
17:
18:
19:
20:
21:
22:
23:
24:
25:
SELECT
  CustInv.TransactionDate
  ,CustInv.UserTranNumber
  ,Cust.CompanyName
  ,CustIDet.AircraftNumber
  ,CustIDet.NumNameCode
  ,CustIDet.Quantity
  ,CustIDet.SalePrice
  ,CustIDet.UnitCost
  ,CustIDet.SalePrice - CustIdet.Unitcost AS Margin
FROM
  CustInv
  JOIN Cust
    ON
       CustInv.CustomerID = Cust.CustomerID
  JOIN CustIDet
    ON
       CustIDet.TransactionID = CustInv.TransactionID
WHERE
  CustInv.TransactionDate BETWEEN @startDate AND @endDate
AND
  CustInv.LocationID = @location
AND
  CustIDet.NumNameCode LIKE 'JET-A%'
ORDER by CustInv.TransactionDate ASC

The results are currently being grouped in the report designer on the field NumNameCode. The values in this field are one of the following:

Jet-A
Jet-A w/Prist
Jet-A * Base
Jet-A * Base w/Prist
Jet-A * Contract
Jet-A * Contract w/Prist
Jet-A * Fractional
Jet-A * Fractional w/Prist

The current grouping keeps them all separated which I know is correct. What I am trying to do is group them into the 4 types regardless if it is w/prist or not. My groups should be:
Jet-A
Jet-A*Base
Jet-A*Contract
Jet-A*Fractional

How can I accomplish this? Do I need 4 individual queries or is there another way to do it?

Answer : SQL server 2008 query with grouping

view the running config of your firewall and look out for rules like this;
ip nat inside source static 172.16.1.1 11.22.33.44
where172.16 or 10.0 or 192.168 can be your private ip range and 11.22.33.44 (respective entry in ur config) is your public IP.
