sql-Zend_Db按字段值排序
作者:互联网
我正在使用以下命令从模型中输出选择菜单的内容:
$select = $this->select();
$select->order('name');
return $this->fetchAll($select);
但是,我要执行的操作是按特定值排序,然后按名称列排序. SQL看起来像这样:
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`
返回值:
6 john
3 andy
2 dave
5 jason
4 paul
1 rob
解决方法:
我相信这是您要寻找的:
$name = 'John';
$order = new Zend_Db_Expr($this->getAdapter()->quoteInto("name = ?", $name) ." DESC, `name`");
$select = $this->select();
$select->order($order);
return $this->fetchAll($select);
