I have the following Doctrine statement which works fine.
$query = $this->createQuery('r')
->select('u.id, CONCAT(u.first_name, " ", LEFT(u.last_name,1)) as full_name, u.first_name, u.last_name, u.gender, r.run_time')
->innerJoin('r.ChallengeUser u')
->orderBy('run_time')
->execute(array(), Doctrine::HYDRATE_ARRAY_SHALLOW);
I need to add a row count into this. Now I know with raw SQL you can do this;
SET @rank=0;
SELECT @rank:=@rank+1 as rank, u.id, u.first_name ....etc
So my question is, how can I get this to run with Symfony 1.4 and Doctrine? I am using MySQL for this project.
Edit... I figured it out..
Doctrine_Manager::getInstance()->getCurrentConnection()->standaloneQuery('SET @rank=0;')->execute();
$query = $this->createQuery('r')
->select('r.run_time, @rank:=@rank+1 rank, r.user_id, CONCAT(u.first_name, " ", LEFT(u.last_name,1)) as full_name, u.first_name, u.last_name, u.gender')
->leftJoin('r.ChallengeUser u')
->orderBy('run_time')
->execute(array(), Doctrine::HYDRATE_ARRAY_SHALLOW);
Add the standalone query in to set the variable, and swap the inner join to a left join.
if you are using MySQL, and no switches to other DBMS are foreseen, maybe you could try
$query = $this->createQuery('r')
->select('COUNT(u.id) as rank, u.id, CONCAT(u.first_name, " ", LEFT(u.last_name,1)) as full_name, u.first_name, u.last_name, u.gender, r.run_time')
->innerJoin('r.ChallengeUser u')
->orderBy('run_time')
->execute(array(), Doctrine::HYDRATE_ARRAY);
