Question

SELECT * 
FROM `users` 
WHERE `lose` > '1' 
AND `win` > '1' 
ORDER BY win DESC 
LIMIT ".$lowerlimit.", 30

这适用于游戏网站上的排行榜。问题是：

Players        Win       Lose
Player 1:      94         40
Player 2:      91         56
Player 3:      9          12
----------------------------
Player 12:     82         50
Player 13:     8          10

玩家12必须在第3位。我做错了什么？

Answer 1

现在，它按字母顺序排序。将发生的所有数据都作为数字并不重要。您需要更新架构以将赢或输存储为数字数据类型，例如：

CREATE TABLE users
(
  players text,
  win int,
  lose int
);

然后将您的查询更改为：

SELECT * 
FROM `users` 
WHERE `lose` > 1
AND `win` > 1
ORDER BY win DESC 
LIMIT ".$lowerlimit.", 30

另外，我想在排行榜上，你想让那些永远迷失的人，对吗？您可能想要删除WHERE lose > 1

Answer 2

如果输赢不是text / ntext列，那么您可以尝试使用以下代码

SELECT * 
FROM users 
WHERE cast(lose as int) > 1
AND cast(win as int)> 1
ORDER BY cast(win as int) DESC
LIMIT ".$lowerlimit.", 30

需要SELECT * FROM的建议
