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.
In connection with several SQL VIEWs added to our CRM product as the
"New Data Access Layer" (mainly for BIRT at this point), we create
user-defined functions, by generating (from an RPG program) and
executing (via RUNSQLSTM) an SQL script.
At present, the RPG program decides whether or not to begin the script
with a DROP FUNCTION, by checking whether the function's *SRVPGM exists.
Unfortunately, if function was already created, and the *SRVPGM for the
function has been deleted without doing a DROP FUNCTION, no DROP
FUNCTION is generated, and the CREATE FUNCTION fails.
Can somebody who's more familiar with SQL suggest a less fragile way of
unconditionally creating (or re-creating) the function and its
underlying *SRVPGM, one that won't break under the described conditions?
