Re: DB2 to MySQL

One up for Marks suggestion using Diters solution.

I have used it in many places with great success. It is logging a little
too much in my opinion ( each row fetched), but since it is open source,
then you can easily change that RPG program and only log negative SQLCODE
values... Those is just minor details

it is using a *ARDPGM as a driver. JVAGATE/JDBCGATE is the name and it is
great !!

Hi Doug

Scott has an example in the source that goes along with his JDBCR4
service program - the QRPGLESRC member is named i MYSQLTEST, and it has
all you need to learn how to INSERT data into a MySQL table.

And here is Scott's presentation on using JDBC - it contains examples on
MySQL and helps you with installing the MySQL JDBC driver.

MySQL has a lot of non-standard SQL syntax - JDBC lets you use standard
SQL with each RDBMS you want to work with - one reason to use it is the
standardization.

Does anyone have any references as to how to set up an RPG program that
can send DB2 data to a MySQL database on a remote server?

I seem to be able to connect to the remote server in a test RPG program
and run a small set of simple commands [get a list of files in its DB],
but an not sure how to use the LOAD DATA LOCAL INFILE MySQL command to
load the DB2 rows. This test RPG program connection uses the JDBCR4
service program from Scott Klement.

There is an existing, buggy Java program the normally does this, but it

is

having problems lately and I was hoping I could rewrite the daily job in
RPG. The Java program appears to get a list of column names for the file
to send and concatenate them together somehow into a predetermined

format.

It then uses a Java command as MYSQL_STMT.setLocalInfileInputStream that
sets the input stream to something set via IOUtils.toInputStream(), which
appears to take the list of column names as input.

I have extremely limited Java experience.

Any resources anyone has to help would be great. Can this be done in
embedded SQL somehow, or is JDBC my only option? The original Java

program

is from 2015, and I assume there have been many improvements to the

system

since then that may allow a better way to do this.

Thank you,

Doug
