从20的一组中选择最多5个整数

Question

我正在尝试从表格中最近20个条目的列表中选择5个查看次数最多的文章.我的表结构基本上是这样的:

id | date | title | content | views

我的第一个想法只是使用内部选择来获取最近的20篇文章,然后从中选择,但我还没有运气.

//doesn't work (my version of mysql doesn't support LIMIT in sub queries)
$recent = "(SELECT id FROM news ORDER BY date DESC LIMIT 20)";
$result = $db->query("SELECT id, title, date, content FROM news WHERE id IN $recent ORDER BY views DESC LIMIT ".self::RECENT_MAX);

//neither does this (syntax error @ 'OFFSET 20')
$recent = "(SELECT MAX(date) FROM news ORDER BY date DESC OFFSET 20)";
$result = $db->query("SELECT id, title, date, content FROM news WHERE date > $recent ORDER BY views DESC LIMIT ".self::RECENT_MAX);

任何人都有关于如何构建此查询的任何建议？

Answer 1

我只是测试了它,它的工作原理

SELECT *
FROM (
    SELECT *
    FROM news
    ORDER BY id DESC
    LIMIT 0, 20
) lasttwenty
ORDER BY views DESC
LIMIT 0, 5
