DB2 Cursor or SQL Cursor or simply cursor is a mechanism by which you access data row-by-row from the result set. Cursors in DB2 keep track of records in the results set, and with the help of cursors, you can update, delete, or select individual rows from the table. Are you planning to use the DB2 Cursor in your COBOL+DB2 applications? If yes, then do watch this COBOL+DB2 cursor video because it will help you in understanding the underlying concept of Cursors in the COBOL+DB2 application/program. This COBOL+DB2 cursor video explains SQL cursor with COBOL+DB2 cursor sample code, DB2 Cursor Stages (i.e. DB2 Cursor life cycle) followed by SQL Code and DB2 Cursor Types.
