【问题描述】：

如何在 Access SQL 数据库表中找到第 11 个条目？我必须使用 TOP 函数，我的查询目前看起来像这样：

SELECT TOP 11 Passenger.Name, SUM(Manifest.Ticketprice) AS [Total Amount Spent on Tickets]
FROM Passenger INNER JOIN Manifest ON Passenger.PassengerNumber=Manifest.PassengerNumber
GROUP BY Passenger.Name
ORDER BY SUM(Manifest.Ticketprice) DESC;

【解决方案1】：

您可以使用子查询：

SELECT TOP 1 T.Name, T.[Total Amount Spent on Tickets]
FROM

(SELECT TOP 11 Passenger.Name, SUM(Manifest.Ticketprice) AS [Total Amount Spent on Tickets]
FROM Passenger INNER JOIN Manifest ON Passenger.PassengerNumber=Manifest.PassengerNumber
GROUP BY Passenger.Name
ORDER BY SUM(Manifest.Ticketprice) DESC) As T

ORDER BY T.[Total Amount Spent on Tickets] ASC

【讨论】：

这给了我数据库中列出的第一个人，而不是第 11 个
是的，我觉得外面的ORDER BY应该是ASC。
@Andre：应该。已更正。谢谢。

【解决方案2】：

SELECT TOP 11 Passenger.Name, SUM(Manifest.Ticketprice) AS [Total Amount Spent on Tickets]
FROM Passenger INNER JOIN Manifest ON Passenger.PassengerNumber=Manifest.PassengerNumber
GROUP BY Passenger.Name
ORDER BY SUM(Manifest.Ticketprice) DESC LIMIT 1;

【讨论】：

访问中没有“LIMIT”关键字。我相信答案是使用嵌套的“TOP”查询：SELECT TOP 1 * FROM (SELECT TOP 11 Passenger.Name, SUM(Manifest.Ticketprice) AS [Total Amount Spent on Tickets] FROM Passenger INNER JOIN Manifest ON Passenger.PassengerNumber =Manifest.PassengerNumber GROUP BY Passenger.Name ORDER BY SUM(Manifest.Ticketprice) DESC);
