Question

Zend Framework DB Select Join table help

Asked by: extrovertive

I have the raw query.


Now, this is my JOIN using zend_db_select but it gives me array error

Anyone know what I could be doing wrong? I want to get all the columns in 'games' to show and the 'rank' column in the ranks table.

SELECT g.title, g.asin, g.platform_id, r.rank
FROM games g
INNER JOIN ranks r ON ( g.id = r.game_id )
ORDER BY r.rank DESC
LIMIT 5`
 
 
///////////////////////////
$query = $this->select();
        $query->from(array('g' => 'games'), array());
        $query->join(array('r' => 'ranks'), 'g.id = r.game_id', array('g.title', 'g.asin', 'g.platform_id', 'r.rank'));
        $query->order('r.rank DESC');
        $query->limit($top);
        $resultRows = $this->fetchAll($query);
        return $resultRows;

Maybe you should move the fields from first table in the from() :

$query = $this->select();
        $query->from(array('g' => 'games'), array('g.title', 'g.asin', 'g.platform_id'));
        $query->join(array('r' => 'ranks'), 'g.id = r.game_id', array('r.rank'));
        $query->order('r.rank DESC');
        $query->limit($top);
        $resultRows = $this->fetchAll($query);
        return $resultRows;

I tried that, but that didn't work.

What exactly is your error ?

 

by: extrovertivePosted on 2009-08-13 at 12:29:44ID: 25091933

I tried:
$query = $this->select();
        $query->from(array('g' => 'games'), array('g.title', 'g.asin', 'g.platform_id'));
        $query->join(array('r' => 'ranks'), 'g.id = r.game_id', array());
        $query->order('r.rank DESC');
        $query->limit(5); print_r($query->__toString()); exit;
        $resultRows = $this->fetchAll($query);
        return $resultRows;

And got the result below. Notice, r.rank is not part of the columns. That's the problem.
-----------

SELECT `g`.`title`, `g`.`asin`, `g`.`platform_id` FROM `games` AS `g` INNER JOIN `ranks` AS `r` ON g.id = r.game_id ORDER BY `r`.`rank` DESC LIMIT 5
------------------

But when I do
--------------------
$query = $this->select();
        $query->from(array('g' => 'games'), array('g.title', 'g.asin', 'g.platform_id'));
        $query->join(array('r' => 'ranks'), 'g.id = r.game_id', array('r.rank'));
        $query->order('r.rank DESC');
        $query->limit(5); print_r($query->__toString()); exit;
        $resultRows = $this->fetchAll($query);
        return $resultRows;

----------------------
I get the error
"Warning: Select query cannot join with another table in C:\phpLib\library\Zend\Db\Select.php on line 1268"
