如何在ZF中编写此查询？

Question

我试图用zf的选择，但没有成功

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

我试图用ssomething这样写这篇文章，查询：

$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().')'); 

任何人都可以帮我解决这个问题！？

Answer 1

这应做到：

$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());

输出：

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

不要让我知道如何去，我用于测试下面的代码，但没有测试执行实际查询，因为我没有这样的数据结构：

$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

你可以试试这个：

$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);
