Table Structure
Location Year Qty1 Qty2 Qty3 Qty4 Qty5 Qty6 Qty7 Qty8 Qty9 Qty10 Qty11 Qty12
Atp 2010 6700 20770 9430 0 0 0 0 0 0 0 0 0
Atp 2010 4209 0 0 0 0 0 0 0 0 0 0 0 null null
in the above table qty1,qty2 represent as month.
If i send month 4
Here i need to calculate (qty1+ qty2+qty3+qty4) current, (qty5+qty6) Forcast. in another column
If i send month 6
Here i need to calculate (qty1+ qty2+qty3+qty4+qty5+qty6) current, (qty7+qty8) Forcast. in another column
How can i bring this result can u please guide me through sample code

It is possible that you can change the design of the table ?
A table with the structure of
Location
Year
Month
Quantity
Would be easier to process.
Whenever I see a table with repeating column names appended with numbers, I cringe in horror.

Here we cant change the table structure. b'coz already running in production server.so that only

Well , you could make the best of a bad job by unpivoting (either by using UNPIVOT or using a case statement) the data first to fake a correct structure.

It does look like the table in your eample is populated by some PIVOTING query. I would recommend to have a look it and see where data is comming from originaly. Then, you can, most likley, easely implement what you want making your quiry on the original source table(s).

I'm not suggesting this is a good idea, but if avoiding dynamic sql is your only consideration then this might work.
Edit: I assumed you wanted the rest of the year in the forecast, if its only the next two months then you would need additional logic.

Hello friend,
Really nice. i got exact result for current value. but forecast value is getting wrong result.
my requirement is
If month is 4
Current value- (Qty1+Qty2+Qty3+Qty4)
forecast value- (Qty5+Qty6)
If month is 5
Current value- (Qty1+Qty2+Qty3+Qty4+Qty5)
forecast value- (Qty6+Qty7)
suppose if its month is 11
Current value- (Qty1+Qty2+Qty3+Qty4+Qty5....+Qty11)
forecast value- (Qty12+0)
if its month is 12
Current value- (Qty1+Qty2+Qty3+Qty4+Qty5....+Qty11+Qty12)
forecast value- (0+0)
How can i bring this result. can you please guide me.

This is even more convoluted, but it might work.
I would be inclined to unpivot the data, but that might be equally clumsy.

Hi,
Really fantastic.Thanx a lot . I have small doubt in this.
(ie.) eg.
If month is 4
Current value- (Qty1+Qty2+Qty3+Qty4)
forecast1 value- (Qty5)
forecast2 value- (Qty6)
If month is 5
Current value- (Qty1+Qty2+Qty3+Qty4+Qty5)
forecast1 value- (Qty6)
forecast2 value- (Qty7)
suppose if its month is 11
Current value- (Qty1+Qty2+Qty3+Qty4+Qty5....+Qty11)
forecast1 value- (Qty12)
forecast2 value- (0)
if its month is 12
Current value- (Qty1+Qty2+Qty3+Qty4+Qty5....+Qty11+Qty12)
forecast1 value- (0)
forecast2 value- (0)
Here i need to forecast two value separtly like forecast 1 and forecast2. How can i make changes in above query. can u please guide me.
