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.

https://www.scottklement.com/presentations/External%20Databases%20from%20RPG.pdf

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.
