Which database object points to a currently selected set of records and can be acted on as a group in many languages?

• A. Cursor
• B. View
• C. Table
• D. Snapshot

Answer: (A)

A cursor is a handle to the result set produced by a query. It points to the current position within that set, allowing you to move through the rows and act on them as you go. This lets you process the selected records in a loop, performing operations on each row or on the current subset as a group, depending on the language and database API. A view is just a saved query presented as a virtual table, not a runtime pointer you carry around. A table is the actual storage of data, and a snapshot is a fixed capture of data at a moment in time. So the cursor best fits the idea of referencing the currently selected set and enabling grouped actions.
