1.
As we know that Implicitly Cursor 'SQL' is opened.
when it is pin pointing the 1st row in the dual, cursor
found that one record exists.

since there are no conditions (i.e., where,group by,..),
directly 'select' clause will be executed.
3.
Internally Oracle identifies numbers, so 10 number will be
displayed.
