我是zend框架的新手。我想从这三个表中透露数据。但是我无法获得此连接查询的正确结果。我在哪里做错了？请帮帮我
如何从此结果集中获取字段？我在查询上方得到了这个结果表单。
SELECT "h".*, "t".*, "c".* FROM "hotels" AS "h" INNER JOIN "roomtypes" AS "t" ON "h"."id" = "t"."hotel_id" INNER JOIN "roomcapacities" AS "c" ON "c"."roomtype_id" = "t"."id" WHERE h.country = USA AND h.state = usas2 AND h.city = usac1 AND c.no_of_adult = 3Zend\Paginator\Adapter\DbSelect Object

答案 0 :(得分：0)
要获得结果，请执行以下操作：
$results = $select->query()->fetchAll();
请注意，查询函数返回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。要更改获取模式，请使用以下代码：
$this->tableGateway->getAdapter()->setFetchMode([fetch mode])
其中fetch模式的可能值被枚举enter link description here。
答案 1 :(得分：0)
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();
它提供了所需的输出。
