Yii - 查找最新用戶的評論

Question

我有一個表名Comment包含字段id, userid, content, posteddate。

我怎麼能找到這個表格中用戶的最新評論（即id = 10）？

Answer 1

$Criteria = new CDbCriteria(); 
$Criteria->condition = "id = 10"; 
$Criteria->order = "posteddate desc"; 

$Comment = Comment::model()->find($Criteria); 

Answer 2

$model = Comment::model(); 
$attributes = ['userid' => 10]; 
$condition = ['order' => 'posteddate DESC', 'limit' => 1]; 

$result = $model->findByAttributes($attributes, $condition);
