mysql - 从联接或子查询中选择记录作为列(子数组)

我有我的桌子

companies (id)
purchase_invoice (id,company_id,date)
items(id,company_id,purchase_invoice_id)
gifted_items(id,company_id,purchase_invoice_id)
rebated_items(id,company_id,purchase_invoice_id)
return_items(id,company_id,purchase_invoice_id)

我需要查询公司的所有采购发票及其在公司id等于（用户选择）的其他表中的关联记录。
我需要所有这些子表结果作为子列（如果我是正确的，idk）。
注：公司id和采购发票id在所有其他表中均为FK
这就是我想要的

 $ledgers = array(
            'com'   => $data['company_id'],
            'sd'    => $data['start_date'],
            'ed'    => $data['end_date']
        );
$purchaseObj = new Application_Model_DbTable_Ledgers();
$purchaseRes = $purchaseObj->getPurchaseInvoices($ledgers);


public function getPurchaseInvoices($ledgers) {
    $sql = $this->select()
            ->setIntegrityCheck(false)
            ->from(array('pi' => $this->_name))
            ->join(array('c' => 'companies'), 'pi.company_id = c.id', array('c.name as companyName'))
            ->join(array('it' => 'items'), 'it.purchase_invoice_id = pi.id');

          //  ->join(array('prm' => 'rebated_purchase_mobiles'), 'prm.company_id = pi.company_id')
           // ->join(array('rpm' => 'returned_purchase_mobiles'), 'rpm.company_id = pi.company_id')
           // ->join(array('pgm' => 'purchase_gifted_mobiles'), 'pgm.company_id = pi.company_id');

$sql = $sql->where('pi.company_id  = ?', $ledgers['com']);

    if (count($ledgers)) {
        if (Performance_Engine::notEmpty($ledgers['sd']) && $ledgers['sd'] != 'sd') {
            $dt = new DateTime($ledgers['sd']);
            $sdate = $dt->format('Y-m-d');
            $sql = $sql->where('CAST(pi.date AS DATE) >= ?', $sdate);
        }
        if (Performance_Engine::notEmpty($ledgers['ed']) && $ledgers['ed'] != 'ed') {
            $dt = new DateTime($ledgers['ed']);
            $edate = $dt->format('Y-m-d');
            $sql = $sql->where('CAST(pi.date AS DATE) <= ?', $edate);
        }
          $sql->group('pi.id');
        $sql->order('pi.id ASC');

        return $sql->query()->fetchAll();
    }
}

我需要像下面这样的结果

Array (

[0] => Array
    (
        [id] => 102
        [company_id] => 8
        [grand_total_price] => 45000

                   'purchase_invoice_id '=> 102
               )
       )
 )

我希望你能理解。请纠正我需要做的事。
我需要做的是采购发票和所有相关联的表作为列，其中将包含所选记录的数组

最佳答案

这在查询中是不可能的。
