There is a new pureQuery course: Developing Database Applications with Optim Development Studio and pureQuery. The course uses the latest Optim Development Studio 2.2.
If you are still using the IBM Data Studio, the old course is a better match: Developing Database Applications with IBM Data Studio and pureQuery. The new course reflects the updates in tooling and our experiences delivering the course.
For those of you on mainframe machines who are aware of the differences between DB2 LUW and z/OS versions: don't worry! The labs and exercises can be run with DB2 z/OS on an IBM System z mainframe.
