为了给出上下文,我们尝试基于Yammer度量信息实现报告功能.

Yammer指标提供有关计时器和仪表的信息,如下所示,

METER_METRIC:
             count = 1
         mean rate = 0.01 count/s
     1-minute rate = 0.00 count/s
     5-minute rate = 0.00 count/s
    15-minute rate = 0.00 count/s

TIMER_METRIC:
             count = 1
         mean rate = 0.01 calls/s
     1-minute rate = 0.01 calls/s
     5-minute rate = 0.00 calls/s
    15-minute rate = 0.00 calls/s
               min = 89.77ms
               max = 89.77ms
              mean = 89.77ms
            stddev = 0.00ms
            median = 89.77ms
              75% <= 89.77ms
              95% <= 89.77ms
              98% <= 89.77ms
              99% <= 89.77ms
            99.9% <= 89.77ms …

我的SQL查询语句如下:

SELECT * FROM `sales_flat_order_grid` AS `main_table` 
LEFT JOIN (SELECT * from `customer_address_entity_varchar` 
WHERE attribute_id=31) AS `ce3` 
ON main_table.customer_id=ce3.entity_id

我需要将它翻译成Magento风格.我试过了

$collection = Mage::getResourceModel('sales/order_grid_collection'); 
$tel = Mage::getModel('eav/entity_attribute')->loadByCode('2', 'telephone');

$collection->getSelect()  
    ->joinLeft(array('ce3' => 'customer_address_entity_varchar'), 'main_table.customer_id=ce3.entity_id', array('telephone' => 'value'))
    ->where('ce3.attribute_id='.$tel->getAttributeId())

但是这不起作用,因为在连接之后应用了where语句导致查询总数小于sales_flat_order_grid.
