Question

I want to run many SQL update queries at one time using JOOMLA 2.5. Below my code:

require_once '../includes/framework.php';  
$query = "UPDATE #__mytable SET myfield='value' where id=1; UPDATE #__mytable SET  
myfield='value' where id=2; UPDATE #__mytable SET myfield='value' where id=3;";  
$db = JFactory::getDbo();  
$db->setQuery($query);  
$db->query();

But it shows me a syntax error. I tried to test directly in MYSQL and it works.

Answer 1

PHP does not allow multiple queries by default. You can force it to do so by adding a parameter to mysql_connect, but I wouldn’t recommend it (it opens huge security holes for SQL injections).

I don’t know how JFactory handles this, but I would be surprised if it were different.
