如何獲得超過100 000個交易和多個交易的交易的Originator_Account_Id。沒有使用有條款？

Question

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

我希望只有100000以上的交易的Originator_ID和超過1個交易而不使用having子句。

Answer 1

如果你只是想知道Originator_Acc_ID一個以上的交易，那麼你可以使用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 

見SQL Fiddle with demo

如果他們有row_number()大於一個就意味着他們有更多的比一筆交易。以上將返回所有那些不止一個。如果你只想要一個以上交易帳戶的列表，那麼你可以使用：

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 

Answer 2

有可能是一個更好的辦法，但是這似乎工作;

;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
