Answer / monika

Yes, we can create a view on a table that really doesn't
exist yet.We can do this by putting a word (Force) in
create view command-

create force view v1 as
select * from emp;

here view gets created but its staus is invalid,its become
valid when we create table emp(table on which view is
defined).

It is true that the force option can be used to create the

Answer / ram

i cannot create a view unless the DBA gives me create view system privilege and to create a view in any schema, rather than just your own we need the create view privilege and be granted the select,insert,update and delete objects on table underlying the view.
synonym is the alias to database object and to hide details of source of the database object. a public synonym is created by the DBA and is available for use by any database user. a private synonym is defined in the schema by the user and is available to the user.
