如何在ZF中編寫此查詢？

Question

我試圖用zf的選擇，但沒有成功

SELECT * FROM `subscribers` WHERE id IN (Select subscriber_id From gs_relations Where group_id=55) 

我試圖用ssomething這樣寫這篇文章，查詢：

$gs_relations = new GSRelations(); 
$part = gs_relations->select()->from('gs_relations',subscriber_id')->where("group_id=$group_id"); 
$select = $this->select()->setIntegrityCheck(false); 
return $select->where('id IN ('.$part->__toString().')'); 

任何人都可以幫我解決這個問題！？

Answer 1

這應做到：

$gs_relations = new GSRelations(); 
$part = $gs_relations->select()->from('gs_relations','subscriber_id')->where('group_id = ?',$group_id); 
$select = $this->select()->setIntegrityCheck(false); 
$select->from('subscribers')->where('id in (' . $part->__toString() . ')'); 
return $select; 

print_r($select->__toString());

輸出：

SELECT `subscribers`.* FROM `subscribers` WHERE (id in (SELECT `gs_relations`.`subscriber_id` FROM `gs_relations` WHERE (group_id = 55))) 

不要讓我知道如何去，我用於測試下面的代碼，但沒有測試執行實際查詢，因爲我沒有這樣的數據結構：

$groupId = 55; 
$part = $this->db->select()->from('gs_relations','subscriber_id')->where('group_id = ?',$groupId); 
$select = $this->db->select()->from('subscribers')->where('id in (' . $part->__toString() . ')'); 
print_r($select->__toString()); 

Answer 2

你可以試試這個：

$groupId = 55; 
$part = $gs_relations->select()->setIntegrityCheck(false)->from('gs_relations','subscriber_id')->where('group_id = ?', $groupId); 
$select = $gs_relations->select()->setIntegrityCheck(false)->from('subscribers')->where('id in ?', $part);
