  right join users as u on (u.id = s.userid)
group by u.id

please help me out with this any help or suggestion would be appreciated

Answer 1

First, I have to say your SQL query is not optimised : your FROM sub-query is useless.

Take a look :

SELECT 
    stkid, 
    s.id AS stk_id, 
    s.userid AS stk_userid,
    s.productid AS productid, 
    u.id AS userid
FROM stocks AS s 
RIGHT JOIN users AS u 
    ON u.id = s.userid
WHERE s.productid = 1
GROUP BY u.id

Direct SQL

The "I just want the answer of this sql", and the simple way is this (in controller) :

    // get the DB link
$pdo = $this->ModelOfThisController->getDataSource()->getConnection();

$sql = "SELECT 
            stkid, 
            s.id AS stk_id, 
            s.userid AS stk_userid,
            s.productid AS productid, 
            u.id AS userid
        FROM (
            SELECT * 
            FROM stocks AS st 
            WHERE st.`productid` = 1
            ) AS s
        RIGHT JOIN users AS u 
            ON (u.id = s.userid)
        GROUP BY u.id
    ";


$req = $pdo->prepare($sql);
$req->execute(array(
    // ':param1' => $param1,
    // ':param2' => $param2,
    ));

$data = $req->fetch(PDO::FETCH_ASSOC);
    // ...

ORM

The other way is with cakePHP ORM but I don't think you can change the FROM to anything else than the models' table name...
