I have a custom post type ENGINEER that is attached to these custom Taxonomies: City, State, Zip.
I messed up on something and I have several Posts that are not attached to a City, State, or Zip.
How do I find these Posts with no City, State, or Zip?
What Have I Done
Well, not much at this point other than research sql queries that will me identify posts where the taxonomy not in (x,y,z) but I'm not having any luck.
I request the answer be in an SQL Query please. Thanks so much.
