Besides using CDbExpression for getting current date time (i.e. new CDbExpression(‘NOW()’); ),
is there any other scenarios CDbExpression can be useful ?

Maybe to call any other database function? 
Or to refer other table fields when using updateAll() for example…
$model->updateAll(array('field1'=>new CDbExpression('field2*RAND()+1')));
