You might be able to do something with a Common Table Expression - it could maybe have the ID and the aggregate functions in it, then JOIN that to the other table - just a quick thought, I've not tried it with your scenario.

As to MySQL, it is known to have several syntactical items that do not align with the SQL standards - DB2 at IBM, and on IBM i, especially, is very compliant.

You're only grouping by ID so you can only include that column in the select list without one of the aggregate functions (sum, min, max, etc.).
Since this works with MySQL, this is a restriction from DB2/UDB, I guess. So I need to do that report "by Hand", with SQL *and* glue code?
