Question

我正在创建一个链接页面，它将显示按live_date排序的所有链接 - 这里的catch是有两种类型的链接 - 提升和非提升 - 其他捕获是 - 列表应按天分组，所以今天链接将返回提升的链接，然后是非提升的链接 - 然后昨天提升和未提升。

Fridays links

-------------
Promoted link
Promoted link
Promoted link
Normal link 
Normal link

Thursdays Links
--------------
Promoted link
Normal link 
Normal link 
Normal link

等等 -

我的架构：

CREATE TABLE `links` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `title` varchar(200) NOT NULL,
  `email` varchar(200) NOT NULL,
  `link` varchar(200) NOT NULL,
  `reciprocal_checkbox` tinyint(1) NOT NULL,
  `recip` varchar(200) NOT NULL,
  `promoted` tinyint(1) NOT NULL,
  `live` tinyint(1) NOT NULL,
  `live_time` datetime NOT NULL,
  `created_at` datetime NOT NULL,
  `updated_at` datetime NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

我认为这样的事情，但我认为它不会创建所有提升的链接，然后是非提升的（由bool定义）

SELECT title, link, live_time FROM links WHERE promoted = 1 UNION SELECT title, link, live_time FROM links WHERE promoted = 0 GROUP BY live_date

Answer 1

你不想分组，你只想订购它们......

SELECT title, link, live_time 
FROM links 
ORDER BY live_date DESC, promoted DESC

PS - 看起来您没有live_date列。你想要这样的东西吗？

SELECT title, link, live_time 
FROM links 
ORDER BY DATE(live_time) DESC, promoted DESC

Answer 2

这个怎么样？

SELECT title, link, live_time FROM links
ORDER BY live_date, promoted

一个查询显示已提升和未提升的链接
