Describe the bug

It's possible to create a stream or table with no value columns using a CREATE TABLE or CREATE STREAM statement. No error is returned.

However, if you try and use the stream or table in a downstream CREATE TABLE AS or CREATE STREAM AS statement you get a error message.

i.e. the table/stream created with no columns isn't useful.
