MySQL, Are views global or per session/connection?

Question

I'm thinking of creating a VIEW to speed up things and my question is: Are VIEWS per session/connection or global?

Example:

User Foo issues a query that creates a VIEW X, then user Foo continues to query
against VIEW X.  
Meanwhile, User Bar issues the same query that creates a VIEW X because the creation and the name is hard coded into the function issuing the query.

Now, does user Foo and user Bar work with the same VIEW X or do they have "private" VIEW X each?

Answer 1

They're created in the database and are not session bound. If the view actually is the same for the different sessions, you can just use CREATE OR REPLACE VIEW I think.
