排名前100的行数

Question

我选择了：

select col1,col2,col3.....sum(colx) from t1 group by col1,col2,col3...

如何：

1-显示排序最高的前100行（colx1）ASC

2-添加行号

Answer 1

使用TOP()和ROW_NUMBER()：

SELECT TOP 100 t.*,
       ROW_NUMBER() OVER(ORDER BY sum_col DESC) as row_number 
FROM(
    select col1,col2,col3.....
           sum(colx) as sum_col
    from t1 
    group by col1,col2,col3...) t
ORDER BY sum_col 

Answer 2

使用ROW_NUMBER和TOP：

SELECT TOP(100)
    col1,
    col2,
    col3,
    SUM(colx),
    Rn = ROW_NUMBER() OVER(ORDER BY SUM(colx) DESC)
FROM t1
GROUP BY
    col1,
    col2,
    col3
ORDER BY Rn
