sql server 2005 - MSSQL Row_Number() over(order by) in MySql

Question

i need to make a group by clause with the following query:

SELECT NAME, SUM(donationvalue) FROM tbl_pdm2k10_Donations
GROUP BY NAME
ORDER BY SUM(donationvalue) desc

but i want a column on the left returning me: 1, 2, 3, 4, 5, etc as as result. In MSSql i would do

  SELECT Row_Number() Over(order by SUM(donationvalue) desc), NAME, SUM(donationvalue)      
 FROM tbl_pdm2k10_Donations
    GROUP BY NAME

is this possible?

Answer 1

set @row:=0;
SELECT 
  @row:=@row+1 as row_numer,
  NAME, 
  SUM(donationvalue) as total 
FROM tbl_pdm2k10_Donations
GROUP BY NAME
ORDER BY total desc
