Views in sql

Views are created in order to store your queries as virtual
table. If there are a lot of columns and we don’t want to
use all columns and make the table simpler, we can create a
view and reuse it repeatedly. Actually, view does not store
any data however, it contains the retrieve statements to
provide reusability. We can create view if we use some
queries mostly.
create view EmployeeInfo as
select first_name || last_name as "Full Name"
from employees;
