findByXXX()
findFirstByXXX()
$model->getUserName()
If you're asking for the ODM:
Does findByXXX() and findFirstByXXX() set automatic binded parameters and types?
No
How I can use magic columns method (i.e., $model->getUserName()).
This is not supported
I though I saw time ago my second question... but maybe it was just imaginations.
Note that a ODM (Mongo) does not implement bound parameters
