    Perhaps this does what you want:

    SELECT sa.*,
       (SELECT ssu.email_address
        FROM supplier_sign_up ssu
        WHERE ssu.supplier_sign_up_id = 42
        LIMIT 1
       )
FROM suppliers_acc sa
WHERE sa.singup_login_id = 138;

    I’m not sure why you are trying to return supplier_sign_up_id from the subquery. You know the value is 42. I suspect you just want email_address.

    Try This,

    SELECT *,
    (SELECT `supplier_sign_up_id` FROM suppliers_acc WHERE singup_login_id = 138 LIMIT 1) as supplier_sign_up_id ,
    (SELECT `email_address` FROM supplier_sign_up  WHERE supplier_sign_up_id = 42 LIMIT 1 ) as email_address
FROM
   `singup_login` 
WHERE
   1;
