in thread s/Perl/SQL/ ?

To nit-pick, != is not standard SQL. <> is. And ANSI SQL has substring(string FROM idx FOR len), as opposed to substr(string, idx, len)

Anyway, good work on the rewrite. I tried it myself and ended up with a similar statement (albeit with a few extra tables).

    Anonymous Monk:

    Nice catches. I've never read the SQL standard, so I should've phrased it something more like "commonly used/implemented". The substr is just a bobble on my side. I'm always using substring in perl and substr in SQL, so you'd think I would be sensitized to checking that, at least.
