Hi,
My experience shows me that RAM and disk is fundamental for any
database, especially MySQL. As much IO load, much more disk preading you
have to take with.

If you set column values to the new (different from current value), you can just use the same WHERE clause
(a subset of a particular table).
One does not require views to restrict access to columns, as MySQL Server
has a sophisticated privilege system. See section 5.4 The MySQL Access
Privilege System (http://www.mysql.com/doc/en/Privilege_system.html).
Maybe this could help you

Hi,
Since subqueries are not allowed in MySQL, this is

Inner join your table with the temporary table.
Even if MySQL allowed subqueries, this is what will
probably happen behind the scene.
