这将如何转换为yii CActiveDataProvider结构？！

 FROM data t2
 WHERE t2.fromNumber = t1.fromNumber)

尝试此代码：未经测试。请检查。

希望您已为此表创建模型。在Model_name

的位置替换您的型号名称

$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)'),
            ));
