I have a table called names with one field 'names'

rowdata:
queti
quest
questi
quetion

I am trying to retrieve the record 'questi' but my query input is "question", but *could* be queition

So basically I am trying to return the "best match" in my table for a given string longer than any record in the table the input variable would never match the full length of any record in the table.

>What if the string is numeric or just random characters?
then, indeed, you are "unlucky", at least with MySQL there will be very difficult to find an alternative with the assumptions you posted...

Bummer, so I guess I would have to do it programtically.  I'll leave this open for a day or two.

Thanks for you help though.
