Does DB2 no scroll cursor have sensitivity to inserts, updates, or deletes that are made to the rows underlying the result table?

This depends on your Db2-version, Db2-platform (z/os, i-series, linux/unix/windows) and the exact syntax you use from which programming language. Without those details your question is too vague.

Among other things, one of the big ones is going to be the isolation/transaction level. But any time somebody is asking a question along these lines, I get the feeling they're not preparing for concurrency, and/or thinking too much along imperative/application programmer lines (say, RBAR). When somebody adds/deletes/changes a row when someone else is reading the table, what do you want to happen? Although note that reader behavior is per-instance, not global. What is it you're trying to do?
