Question

表格的基本结构

event_id | event_name | start_time | end_time |日期

我正在尝试以他们结束的顺序获取事件

查询我试过： -

SELECT * FROM `tablename` ORDER BY date,end_time DESC

但我没有得到预期的结果。

PS： end_time的类型为time，日期的类型为date

编辑：表转储以进行测试

CREATE TABLE IF NOT EXISTS `wp_deals` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT,
  `title` varchar(256) COLLATE utf8_unicode_ci NOT NULL,
  `p_id` bigint(20) NOT NULL,
  `end_time` time NOT NULL,
  `start_time` time NOT NULL,
  `lastactive` date NOT NULL,
  `alldates` varchar(256) COLLATE utf8_unicode_ci NOT NULL,
  `status` varchar(64) COLLATE utf8_unicode_ci NOT NULL,
  `live` tinyint(2) NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci AUTO_INCREMENT=17 ;

Answer 1

我的猜测是你想要最近的日期。如果是这样，您需要desc两次：

SELECT *
FROM `tablename`
ORDER BY `date` DESC, `end_time` DESC;

您的版本从最早的日期开始。这似乎没那么有用。

按日期和时间排序存储在两个不同的列mysql中
