What is the difference between a sensitive and insensitive cursor in DB2?

The key difference between a sensitive and an insensitive cursor in DB2 lies in how they react to changes made to the underlying data. A sensitive cursor reflects all changes made to the data, ensuring that any updates, inserts, or deletes performed by other transactions are visible to the cursor. On the other hand, an insensitive cursor does not reflect such changes and presents a consistent view of the data as it was when the cursor was opened. Sensitive cursors are useful in applications where real-time data updates are essential, while insensitive cursors may be preferred for performance reasons or when data consistency is not critical.
