Answer / sunil maurya
A view is simply the representation of a SQL statement that
is stored in memory so that it can easily be re-used. For
example, if we frequently issue the following query
SELECT empid FROM emp;
I might well want to make this a view (the reality is that
we would probably never create a view for a statement this
simple but we wanted to use an easy example).
To create a view use the create view command as seen in this
example
CREATE VIEW view_emp
AS
SELECT empid FROM emp;
