Question

I am using the following code:

MyClass::model()->deleteAllByAttributes(array('phone_number'=>':phone_number'), '', array(':phone_number'=>$phoneNumber));

And I am getting the following error:

CDbException
SQLSTATE[HY093]: Invalid parameter number: number of bound variables
does not match number of tokens. The SQL statement executed was:
DELETE FROM `my_class` WHERE `my_class`.`phone_number`=:yp0

Answer 1

I believe you don’t need to bind the attributes in the attributes array (as in findAllByAttributes() too). The values in the params array are bound to values in the condition string, not the attributes array, so I believe the following should work for you (and be sanitized):

MyClass::model()->deleteAllByAttributes(array(
    'phone_number'=>$phoneNumber,
));

Alternatively, you could use:

MyClass::model()->deleteAllByAttributes(array(),'`phone_number` = :phone_number',array(
    ':phone_number'=>$phoneNumber,
));

Which would have the same effect… But then you might as well use deleteAll():

MyClass::model()->deleteAll('`phone_number` = :phone_number',array(
    ':phone_number'=>$phoneNumber,
));
