Re: DB2 to MySQL

[Vern Hamberg <vhamberg@xxxxxxxxxxxxxxx>]

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.
