Unable to create view

Question

I want to create a view with the code you may see below. Then, I get error "ORA-00942 table or view does not exist
" when issuing a CREATE VIEW statement. However, I get no error when executing the query. All tables and views exist. What could be wrong? Thanks.

We cannot build stored procedures or views using privileges granted to us through roles. That is just the way the Oracle security model works. Sometimes I understand it, sometimes I think it's weird - it depends whether there's an R in the month. I certainly find it annoying when I'm am trying to develop some code and a lazy DBA has only granted me CONNECT and RESOURCE instead of the precise privileges I actually need.
Privileges granted through roles always work in SQL*Plus.
