exact same query: SELECT (..) WHERE (t.id=:ycp0).

$criteria = new CDbCriteria;
// Classic method
$criteria->addCondition('t.id = :id');
$criteria->params = array(':id' => Yii::app()->user->id);
// Often used in search functions. Note: if passed value is empty, the WHERE is not added!
$criteria->compare('t.id', Yii::app()->user->id);
// This is my current favorite
$criteria->addColumnCondition(array('t.id' => Yii::app()->user->id));
// A bit weird here, but you can also do this
$criteria->addInCondition('t.id', array(Yii::app()->user->id));
