Propel: trying to get the equivalent MySQL clause.

Question

Hi,

I have this propel criteria, and then I try to print the equivalent MySQL clause:

$c = new Criteria();
$c->add(self::USER_ID, 18793);
$result = self::doSelect($c);

echo $c->toString();

But tt print this:

Criteria: SQL (may not be complete): SELECT FROM prenotazione WHERE prenotazione.USER_ID=:p1 Params: prenotazione.USER_ID => 18793

I expected something like this (that give me 1 result from my database, The propel code doesn't retrieve anything...:(. )

 SELECT * 
 FROM  `prenotazione` 
 WHERE  `user_id` =18793

Any explanation?

Regards

Javi
