Answer 2

Bitte siehe das letzte Beispiel (# 17 - ab Zeile 268) eines Kern ich auf Github erstellt: https://gist.github.com/andrewscaya/8b7d53cffd7c1cb61c234c0de126e964

Für die Zukunft:

use Zend\Db\Sql\Select; 
    use Zend\Db\Sql\Where; 
    use Zend\Db\Sql\Expression; 

    $sqlExpression = new Expression('MAX(`sku`)'); 
    $subSelect = new Select(); 
    $subSelect->from('purchases') 
      ->columns([$sqlExpression]); 
    $where = new Where(); 
    $where->in('sku', ['sku' => $subSelect]); 
    $select = new Select(); 
    $select->from('products'); 
    $select->where($where); 

Answer 3

$select = $this->getSql()->select(); 
    $select->join('booking_details','booking_request.book_id = booking_details.book_id',array('car_id', 'car_name','driver_id', 'driver_name'),"LEFT");   


    $select->join(array('DvrExp' => '(SELECT book_id, SUM(amount) AS expenses FROM driver_expense GROUP BY book_id)'),'DvrExp.book_id = booking_details.book_id',array('expenses'),"LEFT"); 
    $select->join(array('PndBal' => '(SELECT book_id, SUM(amount_pending) AS pending FROM payment_balance GROUP BY book_id)'),'PndBal.book_id = booking_details.book_id',array('pending'),"LEFT"); 
    $select->join(array('PymtRcvd' => '(SELECT book_id, SUM(amount) AS receive FROM payment_receive GROUP BY book_id)'),'PymtRcvd.book_id = booking_details.book_id ',array('receive'),"LEFT");  
    $select->where("booking_request.status = '".$booking_type."'"); 
    $this->_set_date_filter($select,$params); 
    $select->where("booking_request.request_date > '2016-06-07 00:00:00'");  

    //echo $select->getSqlString(); die; 
    $resultSet = $this->selectWith($select);   
    return $resultSet;
