Ok, I just saw a post about using view's in mysql. I tried to look it up
and found how to use it, but my question is: what is a view and why would
you use it? Is it like a temporary table? Does it write a new database to
the disk or use memory?
Thanks

Hello,
I'm new to views and am discovering massive performance hits in the views
I've created once the records start to climb above 20,000 or so. Does
anyone know of a great primer/tutorial site for optimizing views in MySQL,
or even generally? What are the best practices etc...? I find when I
Hi there,
Does anyone know how views are implemented in MySQL? Is the view query
