mysql - 使用 cakephp 1.3 从 mysql db 表中的创建日期中选择不同的年份

Question

我有工作的 sql 查询，它为有报告的每一年返回一行。我需要 cakephp 1.3 控制器的语法来获得相同的结果。

SELECT DISTINCT Year( `dated` )
FROM `reports`
ORDER BY Year( `dated` ) ASC

我尝试过的 cakephp 1.3 查询：

$theYear = $this->Model->Database->find('all',array('fields'=>'DISTINCT Report.dated as Year')); // this still returns all entries, not distinct

或者

$theYear = $this->Model->query('SELECT DISTINCT Report.dated from Report as Year ORDER by Report.dated ASC'); // returns bool(false)

还在我的蛋糕模型中尝试了一个功能：

function getYears()
{
    $ret = $this->query
      (
      "SELECT DISTINCT dated FROM reports as Year ORDER BY dated ASC"
     );
    return $ret;
} // returns NULL

预期结果是： 2011 2012 2013

Answer 1

$theYear = $this->Model->Database->find('all',array('fields'=>'DISTINCT Year(Report.dated)' )); // this appears to be the correct syntax
