如何在yii中运行mysql查询 [英] how to run a mysql query in yii

问题描述

我想进行mysql查询以从表中获取列中最高的5个值， 因此查询为:

I want to make mysql query to get the highest 5 values in a column from a table, so the query is :

'SELECT * FROM files ORDER BY  `uploadDate` DESC LIMIT 5'

如何运行此查询并将其值保存在变量中?

how to run this query and save its value in a variable?

如果可能的话，我更喜欢将findAll()方法与这些选项一起使用.

I prefer to use findAll() method with these options if it is possible.

推荐答案

有几种方法可以实现，但是如果您更喜欢查询生成器方法

There are several ways to achieve this, but if you prefer the query builder way

$results = Yii::app()->db->createCommand()->
          select('id, filename, uploadDate')->
          from('files')->
          order('uploadDate DESC')->
          limit(5)->
          queryAll();

var_dump($results);
