Answer 1

请参阅我在Github上创建的要点的最后一个例子（＃17 - 从第268行开始）： https://gist.github.com/andrewscaya/8b7d53cffd7c1cb61c234c0de126e964

供将来参考：

    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;
