I have a DB with images loaded in attachment fields (up to 10 per record, and thousands of records). I need to create space in the DB and I would like to remove many images which are no longer useful using something similar to the update query. However, when I tried it using an update query, I got an error stating that the fields with multiple values (attachement: data, field name, type) cannot be updated or deleted.
Does anyone have any experience on how it can be done via another method?
