->delete() -- Delete items from table
Leírás
Deletes data from the database, either using primary key or based on a
whereAdd() method call.
By default the delete will base it's query on the set variables,
however if you wish to use the
whereAdd()
method you should set the $useWhere parameter to DB_DATAOBJECT_WHEREADD_ONLY.
Visszatérési érték
