A cursor is a programming device that is used to handle the
rows that are returned by the query as the host language
(cobol) can handle only one row at a time. its also a small
file that has the result set. The cursor has to be
declared,opened, fetched and closed to access the data
returnee by the query.

Answer / vinod babu bachina
In DB2 cursor is used to fetch more than one row from a DB2
table. But cursor can fetch only one row at a time. Suppose
if ur retrieving more than one row from table , u have to
use cursor only. If u use SELECT instead of cursor then it
leads to error '' more than one row selected in select'.
