Zend Framework数据库操作技巧总结

$this->fetchAll("is_jian=1","id DESC",0,2)->toArray();
//根据is_jian=1，按id倒序排列取前2条记录当第一个参数为null时，则直接按id倒序排列ASC为正序。

$video=new Video();//实例化数据库类
$this->view->get2Video =$video->get2Video();//取到2条首页推荐的数据

<?php foreach ($this->get2Video as $video): ?>
<?=$video['id']; ?>
<?=$video['name']; ?>
<? endforeach; ?>

$value = $db->quote('St John"s Wort');
// $value 现在变成了 '"St John\"s Wort"' (注意两边的引号)
// 为数组加引号
$value = $db->quote(array('a', 'b', 'c'));
// $value 现在变成了 '"a", "b", "c"' (","分隔的字符串)

echo $where = $db->quoteInto('id = ?', 1);
// $where 现在为 'id = "1"' (注意两边的引号)
// 在where语句中为数组加上引号
$where = $db->quoteInto('id IN(?)', array(1, 2, 3));
// $where 现在为 'id IN("1", "2", "3")' (一个逗号分隔的字符串)

//function quoteInto($text, $value, $type = null, $count = null)
$db = $this->getAdapter();
$sql = $db->quoteInto('SELECT * FROM `m_video` WHERE `is_guo` =?', '1');
$result = $db->query($sql);
// 使用PDOStatement对象$result将所有结果数据放到一个数组中
$videoArray = $result->fetchAll();

$videoArray=$this->fetchAll("is_jian=1 and is_guo=1","id DESC",0,2)->toArray();

$db = $this->getAdapter();
$videoArray=$db->fetchAssoc("SELECT * FROM m_video WHERE `is_jian` = :title",array('title' => '1'));

$db = $this->getAdapter();
$videoArray=$db->fetchCol("SELECT name FROM m_video WHERE `is_jian` = :title",array('title' => '1'));

$db = $this->getAdapter();
echo $videoArray=$db->fetchOne("SELECT count(*) FROM m_video WHERE `is_jian` = :title",array('title' => '1'));

$db = $this->getAdapter();
$videoArray=$db->fetchPairs("SELECT id, name FROM m_video WHERE is_jian = :title",array('title' => '1'));

$videoArray=$this->fetchRow("is_jian=1 and is_guo=1", 'id DESC')->toArray();

//function query($sql, $bind = array())
$db = $this->getAdapter();
$result = $db->query('SELECT * FROM `m_video`');
//$result = $db->query('SELECT * FROM `m_video` WHERE `name` = ? AND id = ?',array('十二生肖奇缘', '1'));
//$result->setFetchMode(Zend_Db::FETCH_OBJ);//FETCH_OBJ为默认值,FETCH_NUM,FETCH_BOTH
//while ($row = $result->fetch()) {
//  echo $row['name'];
