Umm.... umm... hmm... Temporary insanity?

I wish I could. Unfortunately it's not an option, I'm not allowed to modify
the structure of the db on this one.

Well, you see... I took a nap and tried it again... amazing how much easier
it was afterwards. :)

Here's the finished product in case anyone else ever needs to filter
everything except letters and numbers:

SELECT unique_id,
, street_name),'
'!',''),'%',''),'^',''),'*',''),'`',''),'~',''),'|','') AS address FROM
listings HAVING address LIKE '%123EasyStreet%'

I wonder what it would take to get a regex replace function into a future
version MySQL?
