Zend framework2 Zend Framework 2分页联接表

我需要在此代码中添加分页：

    $select = new \Zend\Db\Sql\Select ;
    $select->from('school');
    $select->join('school_parent','school.school_parent_id = school_parent.school_parent_id');
    $resultSet = $this->tableGateway->selectWith($select);
    return $resultSet;

我试过了，但是我不能用联接表

---

有人能帮我吗？

分页应该可以很好地处理联接。这就是我所拥有的，类似于您提供的示例：

$select = new \Zend\Db\Sql\Select ;
$select->from('school');
$select->join('school_parent','school.school_parent_id = school_parent.school_parent_id');

return new \Zend\Paginator\Paginator(
    new \Zend\Paginator\Adapter\DbSelect(
        $select,
        $this->tableGateway->getAdapter()
    )
);

---

如果上述操作不起作用，请发布一个确切的错误。

谢谢您的回答，但我尝试了您的代码，但收到了以下异常消息：

SQLSTATE[42S21]：列已存在：1060重复的列名“school\u parent\u id”

我还试着用Rob Allen的例子来描述我的“连接表”：

public function fetchAll($paginated=false)
     {
          if($paginated) {
        // create a new Select object for the table album
            $select = new \Zend\Db\Sql\Select ;
            $select->from('school');
            $select->join('school_parent','school.school_parent_id = school_parent.school_parent_id');
            // create a new result set based on the Album entity
            $resultSetPrototype = new ResultSet();
            $resultSetPrototype->setArrayObjectPrototype(new School());
            // create a new pagination adapter object
            $paginatorAdapter = new DbSelect(
            // our configured select object
            $select,
            // the adapter to run it against
            $this->tableGateway->getAdapter(),
            // the result set to hydrate
            $resultSetPrototype
            );
            $paginator = new Paginator($paginatorAdapter);
            return $paginator;
        }

        $resultSet = $this->tableGateway->select();
        return $resultSet;    
     }

但是结果是一样的。

}

请尝试连接语法

$select->from('table1')->join('table2', 'table1 = table2', array('table2.colum_to_return1', 'table2.colum_to_return2'));

---

请尝试连接语法

$select->from('table1')->join('table2', 'table1 = table2', array('table2.colum_to_return1', 'table2.colum_to_return2'));

将这一行添加到代码中：

$select->columns(array(new Expression('DISTINCT school.school_parent_id')));

或者像这样：

$select->join('school_parent','school.school_parent_id = school_parent.school_parent_id', array('sp_id' => 'school_parent_id'));
