Question

我的SQL中有2个表：

agames（ game_id （必须与 newentries id 相匹配），结束（1或0））
新条目（ game_id ，创建是应该检查日期的地方）

我希望本周能玩最流行的游戏，而且还没有结束（agames.ended = 1）

如何？我没有运气就尝试过，希望有人可以帮助我！

SELECT 
count(id) as a.rank, 
a.game_id 
FROM a.newentries, b.agames 
WHERE b.ended = 0 AND a.created = THIS_WEEK 
order by a.rank 
desc 
limit 1

SELECT count(id) as a.rank, a.game_id 
FROM a.newentries ne
JOIN b.agames ag ON ne.game_id = ag.game_id
WHERE b.ended = 0 AND a.created BETWEEN CURDATE() - INTERVAL 1 WEEK AND CURDATE()
ORDER BY a.rank DESC LIMIT 1

和相同的SQLFIddle： http://sqlfiddle.com/#!9/190069/1

Answer 1

或者您可以尝试

SELECT count(ne.id) as rank, ne.game_id 
FROM newentries ne
JOIN agames ag ON ne.game_id = ag.game_id
WHERE ag.ended = 0 AND ag.created BETWEEN CURDATE() - INTERVAL 1 WEEK AND CURDATE()
ORDER BY rank DESC LIMIT 1

如果您想获取确切的时间而不只是日期，请使用NOW()而不是CURDATE()。

MySQL中没有任何LAST_WEEK表达式。看到类似这样的内容，您可能会感到困惑：

SELECT Id, SomeField, SomeOtherField,
   SUM(IF(SomeDate BETWEEN CURDATE() - INTERVAL 1 WEEK AND CURDATE(), 1, 0) AS THIS_WEEK,
   SUM(IF(SomeDate BETWEEN CURDATE() - INTERVAL 1 WEEK AND CURDATE() - INTERVAL 2 WEEK, 1, 0) AS LAST_WEEK
FROM SomeTable

此示例将字段名称THIS_WEEK和LAST_WEEK添加到结果集中，分别包含本周和上周发生的日期数。 AS关键字用于在结果集中重命名字段或计算。

编辑：对不起，来晚了。您的另一个问题是SELECT count(id) as a.rank会给您语法错误。 AS用于重命名结果中的列标题，并且列标题中不能包含句点。您将其与指定数据来自哪个服务器（a或b）的想法混淆了。

Edit2：在看到您的SQLfiddle之后，id确实是模棱两可的，因为您在两个不同的表中将其作为名称。您必须指定要选择的一个。我已经编辑了上面的查询。

Answer 2

请尝试

SELECT count(id) as a.rank, a.game_id 
FROM a.newentries, b.agames 
WHERE b.ended = 0 AND YEARWEEK(a.created, 1) = YEARWEEK(CURDATE(), 1) 
order by a.rank desc limit 1

使用可以使用特定模式，例如0->星期日，1->星期一.....
