I wouldn't think that a MySQL driver would work terribly well with a DB2 database?
Is this in relation to DPA or SAM? We don't usually see a driver specified in the connection string as we will use the one we ship with, but I can ask engineering if need be. I just need some clarification on where you are specifying this and in what product?
It sounds like you are trying to use the DB2 template for SAM. Unfortunately, that template uses only the ODBC driver. However, there is nothing stopping you from creating a custom template that would allow you to issue that query using DBD::DB2 using perl.
