doctrine default values and relations

Question

In mysql I can set default value for column like this:

ALTER TABLE <Table> CHANGE <Column> DEFAULT <NEW_DEFAULT_VALUE>

I can retrieve default value:

SELECT DEFAULT(<Column>) FROM <Table> LIMIT 1

Is it possible to achieve this concept with Doctrine?

What I actually need is such methods in my table class:

class UserTable extend Doctrine_Table {
    /* ... */

    /** 
     * @return Doctrine_Record
     */
    public function getDefaultProperty() {
        return ???;
    }
    public function setDefaultProperty($value) {
        /* $value can be either integer or Doctrine_Record */
    }
}
