I have this stored procedure that needs to return a compounded resultset from 3 difference sql queries
alter procedure as [myreport] (@starting date,@ending date)
AS
BEGIN
SELECT O.orderID
   ,H.dateordered
   ,O.secondaryID
   ,O.custname
   FROM Orders as O,
   OrderHeaders as H
   WHERE
   dateordered between @starting AND @ending

AND O.secondaryID = H.secondaryID
     GROUP BY
     O.orderID
   ,H.dateordered
   ,O.secondaryID
   ,O.custname
     ORDER BY
             H.dateordered
END
...so this renders both an orderID and secondaryID . Predicated on each row in this resultset , I need to grab that orderID and input it into this sql statement:
SELECT arrivedate FROM orderauxiliary
        WHERE
        mode = 'action taken'

                     and orderID = O.orderID
        and descrip LIKE '%time of action%' ;

...and also for each row in the main resulset I need to append it to the application's resultset
SELECT actiondate FROM comments
        WHERE
        modetype = 'A1'
        and secondaryID = H.dateordered

        So along with the resultset of the first sql statement/query above, the arrivedate and the actiondate has to be included as this application will display each line (orderid, secondaryid, custname, etc) on a web interface with the corresponding arrivedate and actiondate . For some reason I cannot Declare a @ variable and assign it to the last 2 sql statements for O.orderID and H.dateordered.
        ?? thanks in advance

Pretty sure you just need a couple extra joins here to make this work. Also, please notice that I created an explicit inner join between Order and OrderHeaders. This style of join has been around for nearly 30 years now and should be used in favor of the ANSI-89 style joins as posted.

SELECT O.orderID , H.dateordered , O.secondaryID , O.custname , oa.arrivedate , c.actiondate FROM Orders as O join OrderHeaders as H on O.secondaryID = H.secondaryID join OrderAuxiliary oa on oa.orderID = o.orderID and mode = 'action taken' and descrip like '%time of action%' join comments c on c.secondaryID = H.dateordered and c.modetype = 'A1' WHERE O.dateordered between @starting AND @ending GROUP BY O.orderID , H.dateordered , O.secondaryID , O.custname ORDER BY H.dateordered

I believe this is on the right track, thanks a ton ! I was also considering CTE parsing, or maybe if a CURSOR was the right way to deal with each row for the result, but I'll continue testing.

You should also look into CROSS/OUTER APPLY. This scenario is one of it's main uses.
