Question

Here is a example of the table I want to query:

Contribution_Table
ID     LASTNAME   FIRSTNAME   CONTRIBUTION   YEAR
392    Bob        Sully       0.00           2012
392    Bob        Sully       0.00           2013
392    Bob        Sully       0.00           2014
465    John       Greene      0.00           2012 
465    John       Greene      5.60           2013
465    John       Greene      0.00           2014
892    Jane       Crain       0.00           2012
892    Jane       Crain       0.00           2013
892    Jane       Crain       0.00           2014

I want as a result only a list containing those individuals
who have never made a contribution, like so:

ID     LASTNAME   FIRSTNAME   CONTRIBUTION   YEAR
392    Bob        Sully       0.00           2012
392    Bob        Sully       0.00           2013
392    Bob        Sully       0.00           2014
892    Jane       Crain       0.00           2012
892    Jane       Crain       0.00           2013
892    Jane       Crain       0.00           2014

请注意，John Greene被排除在外，因为他做了 2013年的贡献，即使他没有 2012年和2014年的捐款。另请注意结果列表显示每个人一个人没有会费 - 因为它没有总和或分组由此产生的个人，这很重要。

Answer 1

免责声明：如果在这里使用CTE，则IDK过大。但它有效

with cte as 
(
  select ID, SUM(CONTRIBUTION) as csum from tab group by ID
)
select * from tab where tab.id in (select cte.id from cte where cte.csum = 0)

这会奏效。继承人工作fiddle

Answer 2

我认为你需要的是一个查询

SELECT
    *
FROM
    Contribution_Table

WHERE CONTRIBUTION=0
AND ID NOT IN
    (SELECT ID FROM Contribution_Table WHERE CONTRIBUTION > 0)

如何为每个条目只有零贡献的人选择所有行
