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。
