Thanks for the info. It is on wordpress.com.

As an alternative can I export the data, clean up that column and then import it again.

I assume that I will get double posts unless I delete the existing ones.

Is there a way to backup the DB on wordpress.com hosted before I try this?

Thanks in advance for your help.

Amend the contents of one field. For very specific reasons I want to remove some old IP addresses in the table wp_comments under the column comment_author_ID
