RE: crazy embedded sql performance -- RPG400-L

× The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.

One thing I commonly see that could explain this poor perfomance in native
IO is the use of READE in the loop.  Replacing a READE with READ and a
following test for key value breaks can speed these process up..   Make sure
to specify blocking...

If properly constructed and optimized, I would expect both to perform
similarly.

That's the case. The program is a report that sums up sales in the last
month and compares them with sales for the same products in the preceding
year.
 That makes me very happy. I am usually still more comfortable with SQL than
with classic RPG I/O, and if besides prettier code I'll gain faster
execution, I think everybody will be happy around here.
 Thanks a lot.
