How use LIKE in Yii query builder

问题

How build this query with YIi query builder

SELECT *
FROM `table`
WHERE type_item = 2 AND name_item LIke '%name%'

I tried so

return Yii::app()->db->createCommand()
    ->select('*')
    ->from('{{event_field_variants}}')
    ->where('type_item = :type AND name_item LIKE "%:substr%"', array(':type' => '2', ':substr' => 'name'))
    ->order('variant ASC')
    ->queryAll();

But this query get CdbcException. On Yii documentation are examples only with like or only with simple param.

回答1:

->where('name_item LIKE :substr', array(':substr' => '%name%'))

Just put it in the variables part?
