的Zend框架2分頁表連接

Question

我需要在此代碼添加分頁：

$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; 

我試過this example，但我不能與連接表做到這一點。

任何人都可以幫到我嗎？

Answer 1

分頁應該可以在連接時正常工作。這就是我，類似的例子，你提供：

$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() 
    ) 
); 

請張貼如果上述不工作，你得到一個確切的錯誤。

Answer 2

謝謝你的答案，但我想你的代碼，但我有這個PDOException消息：

SQLSTATE [42S21]：列已經存在：1060重複的列名「school_parent_id」

我也嘗試過，以Rob Allen的例子來適配我的「連接表」：

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;  
    } 

但是結果是一樣的。

Answer 3

public function fetchAll($paginated=false) 
{ 
    if($paginated) { 
     // create a new Select object for the table album 
     $select = $this->getallAlbum(); 


     // create a new result set based on the Album entity 
     $resultSetPrototype = new ResultSet(); 
     $resultSetPrototype->setArrayObjectPrototype(new Album()); 
     // 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; 
} 
function getallAlbum(){ 
    $sql = new Select(); 
    $sql->from('album')->columns(array('id', 'artist', 'title'))->join('albumcategory', 'album.catId = albumcategory.catId', array('catName' => 'catName'), Select::JOIN_LEFT); 
    return $sql; 
} 

Answer 4

// 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'); 

//改變這種像下面

// create a new Select object for the table album 
    $select = $this->yourFunction(); 

//並定義yourFunction中像

function youFunction(){ 
$sql = new Select(); 
$sql->from('school')->columns(array('schoolid', 'schoolname', 'anotherfield'))->join('school_parent', 'school.school_parent_id= school_parent.school_parent_id', array('schoolName' => 'schoolName'), Select::JOIN_LEFT); 
return $sql; 

}

Answer 5

請嘗試連接語法

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

嘗試用另一個例子分頁和排序

### module_config.php ### 
'router' => array(
    'routes' => array(
     'album' => array(
      'type' => 'segment', 
      'options' => array(

       'constraints' => array(
        'action' => '(?!\bpage\b)(?!\border_by\b)[a-zA-Z][a-zA-Z0-9_-]*',

    $albums = $this->getAlbumTable()->fetchAll($select->order($order_by . ' ' . $order)); 
    $itemsPerPage = 10; 

    $albums->current();

Answer 8

此行添加到您的代碼：

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

或者是這樣的：

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