我只想显示每个ID的记录少于10个条目的ID，一个ID可能有几个值，如下面的数据中所示。我想 我已经尝试此查询，但它也选择了记录ID 2

select ID, Name ,LastName ,PaymentDate,POSITION 
    From (select ID, Name ,LastName ,PaymentDate ,ROW_NUMBER() OVER(PARTITION BY ID ORDER BY PaymentDate DESC) AS POSITION

Answer 1

请尝试：

Select ID, Name, LastName, PaymentDate 
    From MyTable 
Where ID in (Select ID From MyTable Group By ID Having Count(*) < 10); 

Answer 2

SELECT ID, COUNT(ID) 
FROM sometable 
GROUP BY ID 
HAVING COUNT(ID) < 10 

Answer 3

你想count(*)，不row_number()：

select ID, Name, LastName, PaymentDate 
from (select ID, Name, LastName, PaymentDate, 
      count(*) over (partition by ID) as cnt 
     from . . . 
    ) t 
where cnt < 10; 

这显示行（你的问题建议是你想要的）。如果你只想要的ID，然后聚集更好：

select id 
from t 
group by id 
having count(*) < 10;
