当我将我的Zend_Db_Table_Abstract与select和join一起使用时，fetchAll返回我一行

Question

I have a problem with my class (extend by Zend_Db_Table_Abstract), it returns with only one row each time with a join and select....

I searched on the internet but I found nothing on this "bug"!

class Api_Model_News extends Zend_Db_Table_Abstract
{
protected $_name = 'news';
protected $_primary = 'news_id';

protected $select;

public function init()
{
  $this->select = $this->select();
}

public function setTimestamp($timestamp)
{
  $this->select
    ->where('news_timestamp >= ?', $timestamp);
  return $this;
}
public function setCategory($id_category)
{
  $this->select
    ->where('bsn_id_category = ?', $id_category);
  return $this;
}

public function getNews()
{
  $this->select
    ->from('news')
    ->joinLeft('business', 'news_id = bsn_id', array());
  $data = $this->fetchAll($this->select);
  return $data->toArray();
}

}

In another function:

$news = new Api_Model_News();                    

if ($id_category != NULL)
  $news->setCategory($id_category);

if ($last_sync != NULL)
  $news->setTimestamp($last_sync);

return $news->getNews();

• When I set id_category and not last_sync => Only ONE row
• When I set last_sync and not id_category => Multiples rows
• When I set last_sync and id_category => Only ONE row

Why? I suppose it's because I use bsn_id_category in select but I don't understand ....

Answer 1

Building on the last answer, try this:

 $this->select(Zend_Db_Table::SELECT_WITH_FROM_PART)
       ->setIntegrityCheck(false)
       ->joinLeft('business', 'news_id = bsn_id', array());

Answer 2

Try to set the integrity check to false as "Setting this flag to false skips the checks for table joins, allowing 'hybrid' table rows to be created" :

  $this->select
       ->setIntegrityCheck(false)
       ->joinLeft('business', 'news_id = bsn_id', array());
