Answer / madhuri

The implicit cursor is used to process INSERT, UPDATE,
DELETE, and SELECT INTO statements. During the processing of
an implicit cursor,Oracle automatically performs the OPEN,
FETCH, and CLOSE operations.

Where as in explicit cursors,the process of its working is
done in 4 steps namely DECLARE a cursor,OPEN a cursor,
FETCH from cursor and CLOSE a cursor.
