Question : SQL Query

i need to make some changes to the structure hope u can help me, "Reporting_Date" format has been changed to varchar "200905" and the amount should be in percentage for eg.

State:   Reporting Date:  Amount_1:   P_amt:
CA       200905           2088        220
CA       200904           1122        255
IA       200905           8520        590
IA       200904           2445        545

Results set should be same as before only the difference is it should be caluclated as below
for example the month of "200905" State "CA" (Amount_1 - Sale_amt) = (2088-220) = 1868 and then (1868*100/1122)(April Amount_1) =166.48

Similarly for 'IA' May month it will be (Amount_1 - Sale_amt) = (8520-590)= 7930 and then (7930*100/2445) (April Amount_1 2445) =324.33

I hope it is clear

Thanks a lot in advance
