Yii - 找到最新用户的评论

Question

我有一个包含字段Comment的表名id, userid, content, posteddate。

如何在此表中找到用户的最新评论（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);
