让magento操作支持直接操作数据库方法_magento教程_php教程

以下直接提供让magento操作支持直接操作数据库修改方法，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
