How to force CDbCriteria to perform a distinct query on one field, and not on all?

Question

MySQL

Good evening.
I pull up the data through Active Record, as an object with conditions I use the CDBCriteria object.

$criteria = new CDbCriteria();

$criteria->distinct = true;
$criteria->select = 'id, alias, title';
$criteria->condition = "urlrouting_show <> 0";
$criteria->order = 'title ASC';

return $this->findAll($criteria);

The alias field may be the same for some records, but due to the inclusion of distinct, these records do not appear in the final selection. I want to enable distinct only for the title field. The SQL analog of this would look like this: Now the SQL analog looks different: Is it possible to do this in Active Record?
SELECT DISTINCT(title), id, alias FROM table
SELECT DISTINCT id, alias, title FROM table

Answer 1

$criteria = new CDbCriteria();

$criteria->select = ['id','alias','DISTINCT(title)'];
$criteria->condition = "urlrouting_show <> 0";
$criteria->order = 'title ASC';

return $this->findAll($criteria);
