I need to create a valid string ([a-z0-9]) from a MySQL (v5.6) field that contains other characters while doing an insert select query.
Now with lower characters this is quite easy: LOWER(ca.attr_de),
But how about the other characters? I have chars of type (ö,ä,ß,é...) in the field.
Is there a simple command in mysql like the LOWER one that will do the job?
