Scenario: A developer is tasked with implementing a feature in an application that requires updating records in a DB2 database based on certain criteria. Which type of cursor would be most suitable for this task and why?

A dynamic cursor would be most suitable for this task because it allows updates to the underlying data set. Unlike static cursors which lock the result set, dynamic cursors can dynamically reflect changes made to the underlying data during the lifespan of the cursor. This flexibility is crucial when updating records based on certain criteria, as it ensures that the cursor sees the most up-to-date data.
