Zend_Db 按字段值排序

Zend_Db order by field Value(Zend_Db 按字段值排序)

问题描述

我正在使用这个从模型输出选择菜单的内容:

I'm outputting the contents of a select menu from a model using this:

$select = $this->select();
$select->order('name');
return $this->fetchAll($select);

但是，我想要做的是按特定值排序，然后按名称列排序.SQL 看起来像这样:

However, what i want to do is order by a specific value, and then by the name column. The SQL would look like this:

SELECT * FROM `names` ORDER BY `name` = 'SomeValue' DESC,`name`

示例 SQL 代码:

CREATE TABLE IF NOT EXISTS `names` (
  `id` int(11) NOT NULL auto_increment,
  `name` varchar(100) NOT NULL,
  PRIMARY KEY  (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=latin1 AUTO_INCREMENT=7 ;

INSERT INTO `names` (`id`, `name`) VALUES
(1, 'rob'),
(2, 'dave'),
(3, 'andy'),
(4, 'paul'),
(5, 'jason'),
(6, 'john');

SELECT *
FROM `names`
ORDER BY `name` = 'john' DESC , `name`

返回:

6   john
3   andy
2   dave
5   jason
4   paul
1   rob

推荐答案

我相信这就是您要找的:

I believe this is what you are looking for:

$name = 'John';
$order = new Zend_Db_Expr($this->getAdapter()->quoteInto("name = ?", $name) ." DESC, `name`");
$select = $this->select();
$select->order($order);
return $this->fetchAll($select);
