yet another seo url question

[eluser]boltsabre[/eluser]
Yeah, in my forum table i have these fields, if you don't have a structure like this you may want to consider doing a redesign:

id (int, primary key, auto increment)
seo-title (varchar)
title (varchar)
content (text)
date-posted (datetime)
...etc etc

My url structure is like this:
myDomain.com/forum/id/seo-title

Where seo-title is just the normal title with every space and special character replaced with a dash - (and some extra coding to make sure i don't end up with seo-titles with multiple dashes like 'this---is--my-seo-title).

And i just query the db using uri->segement->2, that way your only searching a int field, not a id+seo-title field, thus keeping the db queries as speedy as possible!
