mysql - 条件中的子查询 - 将 mysql 转换为具有相同表的 yii CActiveDataProvider

Question

这将如何转化为 yii CActiveDataProvider 结构？!

SELECT t1.*
FROM data t1
WHERE t1.date= (SELECT MAX(t2.date)
 FROM data t2
 WHERE t2.fromNumber = t1.fromNumber)

谢谢

试试这个代码:未经测试。请检查。

希望您已经为这张 table 创建了模型。将您的型号名称替换为 Model_name

$dataProvider=new CActiveDataProvider('Model_name', array(
            'criteria'=>array(
             'condition'=>'t.date = (SELECT MAX(t2.date)
                                     FROM data t2
                                     WHERE t2.fromNumber = t1.fromNumber)'
                       )
    )
    );

这有效:

        $dataProvider=new CActiveDataProvider('Data', array(
            'criteria'=>array(
                'condition'=>'t.date = (SELECT MAX(t2.date)
                FROM data t2
                WHERE t2.fromNumber = t.fromNumber)'),
            ));
