It is my understanding that
$db = JFactory::getDbo(); $db->setQuery($sql); $db->execute(); $numRows = $db->getNumRows();
Does not work in Joomla 3.x, right? I get a "Mysql_num_rows() expects parameter 1 to be resource" error. The query runs fine if I don't call getNumRows(), and I have a try/catch block around the whole thing.
What are we supposed to use instead for say, an update query, where one can't just use loadRowList()?
