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.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
You can either check the SQLSTATE afterwards, or add an indicator variable to your INTO: clause (

Subject: How do I monitor for the message "Indicator variable required" in the following statement?
exec sql Select sum(WBBLT1 + WBBLT2 + wbblt3 + wbblt4 -
wbaqmf - wbrsoq - wbbosq - wbusoq)
into :wQty_on_Hand
from IC140M
where WBPPN = :slptno
and wbco = :slco
and wbwhno = :slloc;
In sql scripts, I have used IFNULL, however, IFNULL is not usable in a RPG program.
This is a 7.2 system.
TIA
