我想按cusotmer名称，其中作为本地金额总和不得超过50000别的我需要删除那些不符合的记录？

如何在sql server 2005中实现它？

这将显示有小于50000的客户：

select CustomerName, sum(LocalAmount) 
from MyTable 
group by CustomerName 
having sum(LocalAmount) <= 50000

请注意，您可以通过CustomerID是更好的分组，如果有一个，因为有可能是重名。然后，你可以这样做：删除：

delete from MyTable 
where CustomerID in (
    select CustomerID 
    from MyTable 
    group by CustomerID 
    having sum(LocalAmount) <= 50000 
)

你怎么知道有一个CustomerID列？即使有一个，它也可能有多个具有相同显示名称的ID。我曾在一个客户购买另一个客户的系统中看到过这种情况，他们更改了显示名称，但FK仍然使用原始ID – 2010-09-09 14:23:41

我不知道这是假设 - 这就是为什么第一个示例使用客户名称的原因。 – RedFilter 2010-09-09 14:25:14

尝试本作的选择：

SELECT * FROM Table 
GROUP BY CustomerName 
HAVING SUM(LocalAmount) > 50000

尝试此删除（修改@ RedFilter的版本）：

delete from MyTable 
where CustomerName in (
    select CustomerName 
    from Table 
    group by CustomerName 
    having sum(LocalAmount) <= 50000 
)

select * from MyTable group by CustomerName having sum(LocalAmount) > 50000

看到好排使用：

SELECT 
    cusotmerName ,SUM(localAmount) 
    FROM YourTable 
    GROUP BY cusotmerName 
    HAVING SUM(localAmount)>50000

删除有问题的行使用：

DELETE YourTable 
WHERE 
    CustomerName IN (SELECT 
          cusotmerName 
          FROM YourTable 
          GROUP BY cusotmerName 
          HAVING SUM(localAmount)<50000 
         )

这句法看起来有点怪异，但它的工程！

;with cte as 
(
select sum(LocalAmount) over (partition by cname) s 
from yourtable 
) 
delete from cte where s <= 50000
