Question

我需要使用以下查询创建group by子句：

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

但是我想要左边的一列回复我：结果是1,2,3,4,5等。在MSSql中我会做

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

这可能吗？

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
