Thanks for the update Stoyan.

I have now used both variations in my projects now as one was symfony based (so the MyQueryClass solution worked perfectly) and one was not (so the initial global function version worked well in this instance).

Also, for symfony:
1. create /yourproject/lib/MyQueryClass.php:

class MyQueryClass extends Doctrine_Query
{
    public function getRawSql()
    {
        $query = $this->getSqlQuery();
 
        foreach ($this->getFlattenedParams() as $param) {
            $query = join(var_export(is_scalar($param) ? $param : (string) $param, true), explode('?', $query, 2));
        }
 
        return $query;
    }
}

Then in yourproject/config/ProjectConfiguration.class.php add the following method:

  public function configureDoctrine(Doctrine_Manager $manager)
  {
    $manager->setAttribute(Doctrine_Core::ATTR_QUERY_CLASS, 'MyQueryClass');
  }

Now you can debug your queries everywhere in the project:

    $query->getRawSql();

I’d propose the following solution:

function getRawSqlQuery(Doctrine_Query $q)
{
    $queryString = $query->getSqlQuery();
 
    foreach ($query->getFlattenedParams() as $param) {
        $queryString = join(var_export(is_scalar($param) ? $param : (string) $param, true), explode('?', $queryString, 2));
    }
 
    return $queryString;
}

This is more generic solution, as it respects all param sections (having, set, join, where). Your solutions works only with the “where” part.
