}

------解决方案--------------------
Tlist 表结构:
id INT 主键 递增
sortid INT 外键
title VARCHAR

Tsort 表结构:
id INT 主键 递增
name VARCHAR

PHP code

$dataProvider = new CActiveDataProvider('Tlist', array(
    'criteria'=>array(
//                'condition'=>'status=1 AND tags LIKE :tags',
//                'params'=>array(':tags'=>$_GET['tags']),
        'with'=>array('sorts'),
    ),
    'pagination'=>array(
        'pageSize'=>5,
        'currentPage'=>1,
    ),
));

$rows = $dataProvider->getData();

foreach($rows as $row)
{
    echo $row->id;
    echo '---';
    echo $row->sorts->name;
    echo '---';
    echo $row->title;
    echo '
';
