Question

I am using cakephp 2.1 and written sql statement as follows.

SELECT * FROM industry
LEFT JOIN movie ON movie.industry_id = industry.id
LEFT JOIN (
        SELECT MAX(id) AS TID ,movie_id FROM trailer
        GROUP BY movie_id

      ) AS c ON c.movie_id = movie.id
LIMIT 0, 4;

where industry is “Industry” model, movie is “Movie” model and trailer is “Trailer” model and I have tried this one.

$options['joins'] = array(
        array(
            'table' => 'movies',
            'alias' => 'Movie',
            'type' => 'left',
            'conditions' => array('Industry.id = Movie.industry_id')), 
        array(
            'table' => 'movie_trailers',
            'alias' => 'Trailer',
            'type' => 'left',
            'conditions' => array('Trailer.movie_id = Movie.id')));

    $trailers = $this->Industry->find('all', $options);

So please suggest me to convert this statement to cakephp statement.

Answer 1

Your SQL is a join with a sub query, while the Cake code is join only.

You can do a sub query but I would look for a way to do it with a join only.

Given the lack of details in your question I cant help with a better query.
