In the process of moving our site from the beta version to the full-fledged site, I need to weed out some entries in a couple of weblogs that no longer fit into the final schema. Because a custom field will be blank in only those now-invalid entries, I can isolate those rather easily.
Presumably, this could be done via phpMyAdmin? Something that would change status to “closed” for any entry in a specified weblog which has nothing in the specified field?
