Hi Steve,
You can join to table functions now. I do a lot with table functions.
That said, it can be challenging to get good performance with table
functions and joins. Their results are a black box that return some data,
and it is therefore difficult for the SQL optimizer to predict that
returned set and optimize it with joined data. As a result, I use them
more for performing actions against the database in the middle of set
processing. I also use a table function to call CL programs in the middle
of set processing. You can get good performance with fetching data via
table functions and joins, but it tends to take more engineering effort to
make that happen versus a query with joins that does not involve table
functions.

Would be neat to have an SQL function return a result set. That way you
could join to the SQL function.
select a.custName, b.ordnum, b.orderDate
from custMaster a
join GetCustomerOrders( a.custNum ) b
