原标题:MySQL delete trailing question marks

I imported data from csv files into a MySQL database, but made the mistake of not removing the trailing spaces in the csv columns. So the spaces are seen as ? at the end of some values in the database (of type Varchar). I want to get rid of these. Can I somehow delete all these ?s in the database in one go? I know of the replace command, but I think that works on a single column of a singe table at a time, which will be very time consuming for me. Could anyone please suggest something better? Thanks!
