mysql - 计算积分后获取用户的位置

Question

我试图在添加点后获取用户的位置。到目前为止，我已经得到了以下工作正常:

SELECT 
    u.userID
,   u.username 
,   SUM(fp.finishingPositionPoints) AS totalPoints

FROM leagueinformation li

INNER JOIN users u ON  u.userID = li.userID
INNER JOIN finishingPosition fp ON  fp.finishingPositionID = li.finishingPositionID

WHERE li.leagueID='1'

GROUP BY li.userID
ORDER BY totalPoints DESC

上面的代码会产生这样的结果:

<小时/>

userID | username | points

--------

1      |   user1  |  150


2      |   user2  |  127

3      |   user3  |  100

-------------------------

根据上面的示例，我如何获得第二个用户位置(例如第二名)？

Answer 1

您可以尝试这样做来获取第二个数据，即添加LIMIT 1,1

SELECT 
    u.userID
,   u.username 
,   SUM(fp.finishingPositionPoints) AS totalPoints

FROM leagueinformation li

INNER JOIN users u ON  u.userID = li.userID
INNER JOIN finishingPosition fp ON  fp.finishingPositionID = li.finishingPositionID

WHERE li.leagueID='1'

GROUP BY li.userID
ORDER BY totalPoints DESC
LIMIT 1, 1 --selects only second item
