Earlier this month a new article "Creating scripts more efficiently in the SQL and XQuery editor" has been published on developerWorks. Some of us are switching from the deprecated DB2 Control Center to the Eclipse-based tooling. Good to know that the same SQL editor is part of Data Studio, InfoSphere Data Architect, and several Optim tools.
The articles describes how man new editor features can be used to efficiently develop SQL scripts or XQuery scripts. It is also a good introduction into how to use the statement editor. What is often done for editing XML-related queries, namely changing the statement terminator, is described as well.
