在t-sql中需要一個簡單的查詢

Question

我有一個查詢，我簡化了我們的目的。你如何達到這個結果？

ID OrigId 
---------- 
1 1 
2 1 
3 3 
4 4 
5 4 
6 6 

Result 

ID OrigId 
---------- 
1 1 
2 1 
4 4 
5 4 

Answer 1

您可以使用HAVING語句

SELECT * 
FROM dbo.Table 
WHERE OrigID IN 
(
SELECT OrigID 
FROM dbo.Table 
GROUP BY OrigID 
HAVING COUNT(*) > 1 
) 

Answer 2

要帶回其中相應的OrigId多次出現在表中的所有行，你可以使用

;WITH CTE AS 
(
SELECT *, 
     COUNT(*) OVER (PARTITION BY OrigId) AS C 
FROM YourTable 
) 
SELECT ID, 
     OrigId 
FROM CTE 
WHERE C >1 

Answer 3

select * 
from selecttest 
where origid in 
(
    select origid 
    from selecttest 
    group by origid 
    having COUNT(*) > 1 
)
