问题描述

限时送ChatGPT账号..

我已经正确设置了 Zend_Db::factory 的参数，然后我查询如下:

I have set up correctly the parameters for Zend_Db::factory and then I am querying like:

$select = $db->select()
->from('imdb')
->limit(10);

$stmt = $db->query($select);
$result = $stmt->fetchAll();

问题:为什么我看不到任何显示?

Question: Why I do not see anything displayed?

我继续并尝试通过创建新对象来显示结果

I continue and I am trying to display results by creating a new object

$moviesTBL = new Application_Model_DbTable_Imdb();
$this->view->albums = $moviesTBL->fetchAll();

如果我将它与视图结合起来，它可以正常工作，但会获取所有行！！！如何让它只获取前 10 个?

If I combine it with a view it works fine BUT fetches all rows!!! How to make it fetch only first 10?

foreach($this->albums as $key=> $value)
{
echo $value ->rank.' '.$value->rating.' '.$value->title.' '.$value->year.' '.$value->number_of_votes.'<br>';
}

推荐答案

尝试这样的事情:

$select = $db->select()
->from('imdb')
->limit(10);

$result = $db->fetchAll($select);

其他例子:

$class = new Zend_Db_Table();
$db = $class->getDefaultAdapter();
$select = $db->select();
$select->from('imdb');
$select->limit(10);

$result = $db->fetchAll($select);

.ini

resources.db.adapter = "pdo_mysql"
resources.db.params.host = "localhost"
resources.db.params.username = "root"
resources.db.params.password = "root"
resources.db.params.dbname = ""
resources.db.params.charset = "utf8"
resources.db.isDefaultTableAdapter = true

Bootstrap.php:

Bootstrap.php:

protected function _initDb() { 
    Zend_Db_Table_Abstract::setDefaultAdapter($this->getPluginResource('db')->getDbAdapter());
}
