So you have a need to craft a new table that consists of columns found in
other tables? I recommend using a view instead rather than to duplicate the
data and needlessly bloat the database. Views behave like tables (except that
you cannot insert or update data through them), so you can run queries against
them and as far as I know create new views from existing views and tables. I
recently started playing around with views at my job and was positively
impressed about how easy they are to create and how much work they save. There
really is no need to store the same piece of data more than once in a
database. Works well for tables that are commonly joined or pieces of data
that need to be calculated, filtered, sorted, or whatever SQL allows you to do.
In regards to naming, looking at other databases the views are prefixed with
"v_" or some use "vw_". So in your case the name could be "v_account_user".
Might that work for you?
