Defining and Using Views

Create a view with a static result set:

create or replace view viewzoo.example.hello as select * from (values (1, 'a'), (2, 'b'), (3, 'c')) as t (key, value)

Select rows from the view:

select * from viewzoo.example.hello

Delete the view:

drop view viewzoo.example.hello
