Re: using RPG to access MYSQL files

Alan,

You are correct that the tables are just DB2 tables. The problem is that
the table names from the storage engine have double quotes around the
table name. The RPG F spec does not support the double quote special
character in the file name.

The work around is to use OVRDBF before accessing the file. The OP had a
problem doing a CRTDUPOBJ in order to compile his program.

Dale,

I don't have the storage engine loaded yet, but instead of doing the
duplicate object and OVRDF, have you tried using the EXTFILE keyword on
the F spec? I don't know if it would work, but it is logically the same
thing.

Re: using RPG to access MYSQL files






I am confused here.

If you are using the IBM DB2 engine doesn't that just mean that the tables
are just ordinary AS/400 tables which you could access with embedded SQL
or
File I/O. (Highly recommend using Embedded SQL so that you break your
program ever time the table gets changed by MYSQL)?

The link provided is to access MySql on another server via Java. I am
hearing that the data is stored on the AS/400 which makes them ordinary
AS/400 tables.

Am I missing something?

If you look in the schema (Library) what do you do see? You should see
physical files and if you display the physical file description you should
see the short and the long name. If the long name is 10 characters or less
you will just see the short name.

You could also look at the schema via Ops Nav.

I need help figure out how to use RPG or CL to access MYSQL data

created

using the new IBMDB2I engine in MYSQL version.


We have installed the latest version of MYSQL 5.1.34. Then we

installed

SUGARCRM with test data. PHPMYADMIN shows the test files using the
new IBMDB2I engine.

We followed the IBM redbook "using ibm db2 for i as a storage engine

of

mysql" .Everything seems to have worked as the redbook says it would.
But I am stuck on chapter 4, trying to get to the sugarcrm test files
through rpg.

On page 78, it seems the redbook authors say all I need to do is

create

a duplicate object as a file template and compile my rpg program using
it. But CRTDUPOBJ does not seem to know about QSYS2 and other such
things.

I like the idea of creating a dummy duplicate object for RPG compiles.

For example, SUGARCRM has a masterfile called ACCOUNTS (probably lower
case).

We know our catalog name is our I series serial number. The schema
(LIBRARY?)is sugarcrm (in lowercase). The table name is accounts (in
lowercase, probably with " around it).


Can anyone point me in the right direction?
