Cursor : It's a private SQL worksheet area where we can
execute SQL commands and processing information.
The purpose of the Cursor is, PL/SQL execution block will
process only one records means it will return only one
records.If we want to retrieve or process more number of
records we use the "Cursors".
These are of two types.
1. Implicit Cursor 2. Explicit cursors.
