mysql - Remove special characters from a database field

Question

I have a database with several thousand records, and I need to strip down one of the fields to ensure that it only contains certain characters (Alphanumeric, spaces, and single quotes). What SQL can I use to strip any other characters (such as slashes, etc) from that field in the whole database?

Answer 1

update mytable
set FieldName = REPLACE(FieldName,'/','')

That's a good place to start.
