Re: Excel VBA issued OVRDBF runs in QZRCSRVS not QZDASOINIT -- MIDRANGE-L

IMHO his allows for complete portability of non-IBM i application. Develop on the PC, deploy to any OS/DB. Use pure SQL in the application and requires one program deployment on the i. Couldn't be simpler. My Attendance Management system was developed in Java on the i using legacy tables using multiple membered files. When it came time to deploy on Windows using MS SQL server, no problem. Change a property that turns off the call to the overrides in the DB routines and and I have a DB portable app.

This *isn't* Java specific. The example was a Java app, but I use the same technique for an IVR application running on Windows NT, a JRuby app running on i, my open source sites (PHP) running in Windows. One CL and a plethora of external and internal SQL apps that can use it. Flexible and easy.

I avoid it since that's so easily done. I prefer logic like CREATE ALIAS /
SELECT / DROP ALIAS rather than OVRDBF, so haven't watched developments in
this area. It's a purer, SQL-based solution not involving other programming
languages (Java, CL) and probably easier to understand/maintain. One
implementation change can break your approach. YMMV.

It doesn't? I have an ODBC/JDBC application that that sets overrides
at
connection time and it works just fine. I wrote a small Java wrapper
that calls a CL that sets the overrides at connection time in my Java
apps. I all use the same CL to set overrides at connection time using
an Exit Point program (EXITPNT(QIBM_QZDA_NDB1) FORMAT(ZDAD0200))

Yes. This is the only way, since SQL does not honor OVRDBF.

When using SQL to access data in file members other than *FIRST, I
usually
do a CREATE ALIAS to that member. It's a one-time operation for each
member.
