Default Re: help request for sql select

ahum a bit too cloudy....

if you want to have the max value from a table in your select list you
may want to consider an spl.

quick and dirty....eq:

create procedure mymaxorder_num( f_customer_num like
orders.customer_num)
returning int;

define retval int;
let retval = -1;
select max(order_num) into retval from orders
where customer_num = f_customer_num;

return retval;
end procedure;

select customer_num, lname , mymaxorder_num(customer_num)
from customer

if V db >= 9 then replace procedure by function.
