Get raw sql from Phalcon query builder
you can use getRealSqlStatement() (or similar function name) on the DbAdapter. See http://docs.phalconphp.com/en/latest/api/Phalcon_Db_Adapter.html
According to documentation you can get this way the resulting sql query.
Or wait, this might not work on querybuilder. Otherwise you can setup low level query logging: http://docs.phalconphp.com/en/latest/reference/models.html#logging-low-level-sql-statements
By error and trial the below seems to working. Would be great if someone could confirm if there's a better way.
$queryBuilder = new Builder();
$queryBuilder->from(…)->where(…);
$intermediate = $queryBuilder->getQuery()->parse();
$dialect = DI::getDefault()->get('db')->getDialect();
$sql = $dialect->select($intermediate);
Edit: As of 2.0.3 you can do it super simple, see comment for full details:
$modelsManager->createBuilder()
->from('Some\Robots')
->getQuery()
->getSql()
