Question

我要求制作这样的销售报告：

Product Name         First Week   Second Week  Third Week
   a                      12            6           2
   b                       0            0           4 
   c                       0            3           0

为此我创建了一个返回sku和sum（qty_ordered）的函数，如

   $query = Mage::getResourceModel('sales/order_item_collection');

   $query->getSelect()->reset(Zend_Db_Select::COLUMNS)

    ->columns(array('name','qty_ordered'))
    ->where(new Zend_Db_Expr('created_at BETWEEN NOW()-INTERVAL 1 WEEK AND NOW()'))
    ->group(array('sku'));

   $query->getSelect()->columns(array(
        'week1' => 'SUM(main_table.qty_ordered)')
    );

上面的SQL查询是：

 `SELECT `main_table`.`sku`, `main_table`.`qty_ordered`, 
 SUM(main_table.qty_ordered) AS `week1` 
 FROM `sales_flat_order_item` AS `main_table` 
  WHERE (created_at BETWEEN NOW()-INTERVAL 1 WEEK AND NOW()) 
 GROUP BY `sku

但上述回报仅持续1周。如果我将created_at BETWEEN NOW()-INTERVAL 1 WEEK AND NOW()更改为created_at BETWEEN NOW()-INTERVAL 2 WEEK AND NOW()，则会返回2周的销售额。但我希望结果如上所示。那么我该如何定制呢。帮助我。

Answer 1

`SELECT `main_table`.`sku`, `main_table`.`qty_ordered`, 
 SUM(main_table.qty_ordered) AS `week1`, 
 SUM(if (created_at BETWEEN NOW()-INTERVAL 2 WEEK AND NOW(), main_table.qty_ordered,0)) AS `week2`, 
 SUM(if (created_at BETWEEN NOW()-INTERVAL 3 WEEK AND NOW(), main_table.qty_ordered,0)) AS `week3` 

 FROM `sales_flat_order_item` AS `main_table` 
  WHERE (created_at BETWEEN NOW()-INTERVAL 3 WEEK AND NOW()) 
 GROUP BY `sku`

按周计算销售产品，如第1周，第2周，第3周，第4周
