php pdo此查詢未運行，但它在phpmyadmin上運行順利

Question

此查詢順利運行於phpmyadmin。但在我的項目中，這不是查詢。

$sql = 'SELECT p.est_id,p.sec_plan_number,p.plot_plan_number, 
        (select policyno from tbl_plot_statusd where est_id=p.est_id 
        and sec_plan_number=p.sec_plan_number and plot_plan_number=p.plot_plan_number 
        and op_id=ps.op_id) as policyno, (select nic from tbl_plot_statusd 
        where est_id=p.est_id and sec_plan_number=p.sec_plan_number 
        and plot_plan_number=p.plot_plan_number and op_id=ps.op_id) as nic 
        FROM `tbl_plot` p left join tbl_plot_status ps on p.est_id=ps.est_id 
        and p.sec_plan_number = ps.sec_plan_number and p.plot_plan_number=ps.plot_plan_number 
        where ps.status_type_code=2 and ps.is_last_status=1 and p.isactive=1 
        order by ps.est_id,ps.sec_plan_number,abs(ps.plot_plan_number)'; 
foreach ($db->query($sql) as $d)

嘗試

$query = $db->query($sql); 
foreach ($query->fetchAll() as $d) 
{ 

}
