SQL根據其他列生成順序ID

Question

也許最好用一個例子來說明我要做什么:)

說我有下表

SELECT *
INTO #OrderRanking
FROM (
    SELECT 'Jim', 1000
    UNION ALL
    SELECT 'Jim', 500
    UNION ALL
    SELECT 'Jim', 500
    UNION ALL
    SELECT 'Jim', 3000
    UNION ALL
    SELECT 'Bob', 1000
    UNION ALL
    SELECT 'Bob', 2000
    UNION ALL
    SELECT 'Bob', 500
    UNION ALL
    SELECT 'Bob', 500
    UNION ALL
    SELECT 'Fred', 500
) AS t(Customer, OrderTotal)

我想要的是SELECT語句中的以下結果

Customer, OrderTotal, CustomerId
'Jim', 1000, 1
'Jim', 500, 1
'Jim', 500, 1
'Jim', 3000, 1
'Bob', 1000, 2
'Bob', 2000, 2
'Bob', 500, 2
'Bob', 500, 2
'Fred', 500, 3

我的實際查詢有點復雜，其中源列大於2。

Answer 1

我是個pil子

SELECT *, DENSE_RANK() OVER(ORDER BY Customer DESC)
FROM #OrderRanking

我認為這應該涵蓋所有情況！

Answer 2

select customer, ordertotal, dense_rank() over(order by total desc, customer asc)
from (select *, sum(ordertotal) over(partition by customer) total from  #orderranking) t
