Deleting a Record
Use the delete method to remove records from the database.
$db = Factory::getContainer()->get('DatabaseDriver');
$query = $db->getQuery(true);
// delete all custom keys for user 1001.
$query->delete($db->quoteName('#__user_profiles'))
->where($db->quoteName('user_id') . ' = :user_id')
->where($db->quoteName('profile_key') . ' = :profile_key')
->bind(':user_id', 1001, \Joomla\Database\ParameterType::INTEGER)
->bind(':profile_key', 'custom.%');
$db->setQuery($query);
$result = $db->execute();
