Zend Framework教程之Zend_Db_Table_Row用法实例分析

<&#63;php
// 设置一个 adapter
require_once 'Zend/Db.php';
$params = array (
  'host'   => '127.0.0.1',
  'username' => 'malory',
  'password' => '******',
  'dbname'  => 'camelot'
);
$db = Zend_Db::factory('PDO_MYSQL', $params);
// 为所有的Zend_Db_Table对象设置默认adapter
require_once 'Zend/Db/Table.php';
Zend_Db_Table::setDefaultAdapter($db);
// 连接到数据库中的某一个表
class RoundTable extends Zend_Db_Table {}
$table = new RoundTable();
&#63;>

<&#63;php
// 从表中取回的结果数据是一个Zend_Db_Table_Row对象
$row = $table->fetchRow('first_name = "Robin"');
//
// $row现在是一个带有多种公有属性的Zend_Db_Table_Row对象
// that map to table columns:
//
// $row->id = '3'
// $row->nobleTitle = 'Sir'
// $row->firstName = 'Robin'
// $row->favoriteColor = 'yellow'
//
&#63;>

<&#63;php
// 连接到数据库中的表
class RoundTable extends Zend_Db_Table {}
$table = new RoundTable();
// 从表中取回的结果数据是一个Zend_Db_Table_Row对象
$row = $table->fetchRow('first_name = "Robin"');

// that map to table columns:

// $row->id = '3'

// 改变favorite color字段,并且将变动存储到数据表中.

// 我们尝试修改主键值
