I would like to have a query replace a NULL in a field with a truncated value from one field based on a size passed in?

Basically, I'd like to be able to generate a 'short title' for a record based on either the user's input for a short title, or a turncated 'normal title' at query time.

Would this be very expensive processor timewise?

I might just feed the whole long title in and have the display properties of the browser truncate it.
