I had one table where the column col contained 17 characters. I had to update the character on the 14th position in that field. When the 14th position contained a '1', it should update to '0' This statement worked, thanks to the replace mysql attention in your article, it works like a charm. Thanks a bunch!

UPDATE tbl SETcol= REPLACE(col, '1', '0') WHERE substr(col`,14,1) = '1'

Thanks for posting this - I had a problem with my Drupal 5 installation, where I'd inadvertently copied a modules folder into my existing modules folder, and the system table got updated with these references.

Anyway, this code allowed me to delete the nested folder and update the references correctly. Thank you.
