sql-server - 如何获取超过 100 000 笔交易和多笔交易的 Originator_Account_Id。不使用have子句？

Question

Originator_Acc_ID     |      Transaction_Amount  
-----------------------------------------------
001                   |           10000000 
001                   |           20000000
003                   |               1000 
002                   |           60000000

我想要 Originator_ID 仅用于 100 000 以上的交易和超过 1 个交易，而不使用 have 子句。

Answer 1

如果您只想知道Originator_Acc_ID多笔交易，那么您可以使用 row_number：

select Originator_Acc_ID, Transaction_Amount
from
(
  select Originator_Acc_ID, Transaction_Amount,
    row_number() over(partition by Originator_Acc_ID order by Originator_Acc_ID) rn
  from yourtable
  --where Transaction_Amount > 100000
) src
where rn > 1

请参阅带有演示的 SQL Fiddle

如果他们有一个row_number()大于一个，则意味着他们有多个事务。以上将返回所有超过一个的人。如果您只想要一个包含多个交易的帐户列表，那么您可以使用：

select distinct Originator_Acc_ID
from
(
  select Originator_Acc_ID, Transaction_Amount,
    row_number() over(partition by Originator_Acc_ID order by Originator_Acc_ID) rn
  from yourtable
  --where Transaction_Amount > 100000
) src
where rn > 1

甚至：

select Originator_Acc_ID
from
(
  select Originator_Acc_ID, Transaction_Amount,
    row_number() over(partition by Originator_Acc_ID order by Originator_Acc_ID) rn
  from yourtable
  --where Transaction_Amount > 100000
) src
where rn = 2

可能有更好的方法，但这似乎有效；

;WITH MyTable AS
(
    SELECT   Originator_Acc_ID  = '001'
            ,Transaction_Amount =  10000000
    UNION ALL
    SELECT '001', 20000000
    UNION ALL
    SELECT '003', 1000
    UNION ALL
    SELECT '002', 60000000
)
,CTE AS
(
    SELECT   Originator_Acc_ID
            ,Transaction_Amount
            ,TxnPerOrig = COUNT(*) OVER (PARTITION BY Originator_Acc_ID)

    FROM MyTable
)
SELECT DISTINCT Originator_Acc_ID
FROM CTE
WHERE Transaction_Amount > 100000
AND TxnPerOrig > 1
