in-line view ^ ANSI view: SELECT from SELECT

select * from (select * …. )
NOT a sub-query. supported in oracle and mysql5
Now an ANSI standard view is very similar. Basically a saved query to be used as a fake table, a select-query to be used in FROM, ie select from select.
The starting point to learn inline view is a standard ANSI view.

I would say Oracle supports 2+1 types of views
* ANSI standard view
* materialized view — see earlier posts
* inline view — no name. query not saved with a name
