Question

你好，这是我的困境。我有2个表，一个叫user和user_betting。我正在使用的用户将他们的名字加入到以下链接中的结果中。这是user_betting的表结构。

id
handicapper_id
game_id
sport
date_placed
ML_team
ML_decision
ML_points
ML_awarded
OU_team
OU_decision
OU_points
OU_awarded
SPREAD_team
SPREAD_decision
SPREAD_points
SPREAD_awarded

如果您浏览此页面。 http://wewatchcappers.com/rankings_full.php?sport=MLB您目前可以看到我可以将数据提取30/60/90天。但是我这样做的方法并不能让我排序最高分。基本上需要发生的是我需要计算他们在任何* _decision中获得单词win / tie / loss的次数。这些点必须是* _awarded的总和。这些可能是负数和正数。

我相信我需要将它输入一个数组然后对其进行排序，但我不知道最好的方法。谁能帮到我这里？

这是我目前完成的方式。

<?php foreach($conn->query("SELECT * FROM users INNER JOIN user_betting ON users.id=user_betting.handicapper_id WHERE sport = '$sport' AND date_placed BETWEEN DATE_SUB(NOW(), INTERVAL 30 DAY) AND NOW() GROUP BY user_betting.handicapper_id") as $rankings) { ?>
                            <tr>
                                <td><a href="<?php echo $rankings['username'];?>"><?php echo $rankings['username']; ?></a></td>
                                <td align="center">

Answer 1

SELECT (SUM(LEN(OU_DECISION),LEN(ML_DECISION),LEN(SPREAD_DECISION)) - SUM(LEN(REPLACE(OU_DECISION, 'win', '')),LEN(REPLACE(SPREAD_DECISION, 'win', '')),LEN(REPLACE(ML_DECISION, 'win', ''))))/3

你想要减去所有文本的长度而没有＆＃34; win＆＃34;使用＆＃34; win＆＃34;。

这个词的所有文本的长度

sum of all text - sum of text without "win"

这将为您提供＆＃34; win＆＃34;你拥有的角色，你应该除以3来知道这个词被说了多少时间。

MySQL / PHP分组结果基于日期范围和用户ID
