Cursor-based records in PL/SQL allow you to fetch and manipulate data from a query result set using a cursor. A cursor is a database object that enables you to retrieve rows from a result set one at a time. By using cursor-based records, you can define a record type based on the structure of the result set returned by a cursor, making it easier to work with the individual columns of each row. This approach enhances code readability and simplifies data handling within PL/SQL blocks.
