Difference between CActiveRecord->_attributes and CActiveRecord->getMetaData()->columns

Yii 1.1 General Discussion

CActiveRecord.attributes returns attributes values.

CActiveRecordMetaData.columns returns an array of columns - CDbColumnSchema objects.

You can use CVarDumper::dump() method to see it by yourself ;)
