问题发生在连接查询结果显示中

$select  = new Select(); 
     $select ->from(array('h' => 'hotels'), 
       array('*')) 
     ->join(array('t' => 'roomtypes'), 
       'h.id = t.hotel_id') 
     ->join(array('c' => 'roomcapacities'), 
       'c.roomtype_id = t.id') 
     ->where('h.country = '.$country_code) 
     ->where('h.state = '.$state) 
     ->where('h.city = '.$city) 
     ->where('c.no_of_adult = '.$adults); 

     print $select->getSqlString(); 

     $rowset = new DbSelect($select , $this->tableGateway->getAdapter());

我是新来的zend框架。我想从这三张表中提取数据。但是我无法得到这个连接查询的正确结果。我在哪里做错了？请帮我问题发生在连接查询结果显示中

如何从此结果集中获取字段？我得到这个结果表单上面的查询。

什么结果是正确的？ – voodoo417

为什么这个标记为mysql – Strawberry

任何人都可以请给我正确的方式来执行此查询？ –

为了获得满意的结果，具体操作如下：

$results = $select->query()->fetchAll();

注意查询函数返回一个Zend_Db_Statement对象。根据应用于数据库适配器的提取模式，您将获得一个数组或一组对象或两者作为结果。要更改提取模式，使用此代码：

$this->tableGateway->getAdapter()->setFetchMode([fetch mode])

其中用于提取模式的可能值列举enter link description here。

我解决了这个问题。

$resultSet = $this->tableGateway->select(function (Select $select) use($where) { 
      $select->columns(array()); 
      $select->join(array('h' => 'hotels'),'h.id = roomtypes.hotel_id',array("id","hotel_code")); 

return $resultSet->buffer();

它给出了期望的输出。
