magento直接操作数据库

查：

    $read =Mage::getSingleton("core/resource")->getConnection('core_read');

    $sql = "select * from`abc`";    

    $result =$read->fetchAll($sql); //fetchRow查找一条

增，删，改

    $write=Mage::getSingleton("core/resource")->getConnection('core_write');

     $sql ="insert into abc (name)values('hello')";

    $write->query($sql);

另一种写法：

增

     $write=Mage::getSingleton("core/resource")->getConnection('core_write');

     $table=Mage::getSingleton('core/resource')->getTableName('abc');

    $write->insert($table,array('name'=>'hello'));

改

     $write=Mage::getSingleton("core/resource")->getConnection('core_write');

    $table =Mage::getSingleton('core/resource')->getTableName('abc');

   $write->update($table,array('name'=>'abc'),array('id=?'=>3));

删

       $write =Mage::getSingleton("core/resource")->getConnection('core_write');

    $table =Mage::getSingleton('core/resource')->getTableName('abc');

   $write->delete($table,array('id=?'=>3));

查

     $read=Mage::getSingleton("core/resource")->getConnection('core_read');

    $table =Mage::getSingleton('core/resource')->getTableName('abc');

       $result =$read->select()->from(array('main_table'=>$table))->where('main_table.id=?',3)->limit(1);

      $products=$read->fetchAll($result);

唯一不同的只是一个sql语句是组装的，一个是直接写的
