Re: SQL: Joining on three part names.

I ran this:

create function rob."gdi.erplxf.rco" ()
returns table
( cmpny dec (2 ),
cmpnam char (30))
language sql
return
select cmpny, cmpnam
from gdi.erplxf.rco
Function gdi.erplxf.rco was created in ROB.

I tested that with:
select b.cmpny,b.cmpnam
from table("gdi.erplxf.rco"()) b
SELECT statement run complete.

Then I ran this:
select a.cmpny ,a.cmpnam
from gdisys.erplxf.rco a
SELECT statement run complete.

But I can't run this:
select a.cmpny, a.cmpnam, b.cmpnam
from gdisys.erplxf.rco a
join table("gdi.erplxf.rco"()) b
using (cmpny)

It aborts with:
SQL0205
Message . . . . : Column CMPNY not in table RCO in ERPLXF.

Wait, it's the usual bugs with "USING". This works:
select a.cmpny, a.cmpnam, b.cmpnam
from gdisys.erplxf.rco a
join table("gdi.erplxf.rco"()) b
on a.cmpny=b.cmpny
SELECT statement run complete.
