You can probably get around this by either passing the string from the
form padded with leading and trailing %'s, or noting that the % sign is a
SQL wildcard, since you're using MySQL.

This is actually something I'm looking at doing myself. Long term, I want
to make my CircleMUD backend different pieces into an SQL DB. Has anyone
here taken an existing code base like one of the Diku derivatives and
moved it into a SQL DB store?

Some of the new additions I am putting directly into the DB, eg., my note
system that is mostly ported from ROM, the bank system I am going to be
writing, etc.
