    orderid,customerid from orderdetail

    the sql can't be run in ms sql and is there any similar approach?

    Default Re: subquery with more than 1 fields

    row constructor is not supported yet. a *cheap* workaround is

    select *
    from ordermaster
    where orderid+'|'+customerid in(select
    orderid+'|'+customerid from orderdetail)

    SELECT M.*
    FROM ordermaster AS M
    JOIN
    (SELECT orderid, customerid
    FROM orderdetail
    GROUP BY orderid, customerid) AS D
    ON M.orderid = D.orderid AND M.customerid = D.customerid
