[NTLUG:Discuss] Filtering a list with a list

[Ralph Green]

Howdy,
  Assuming these entries are in a SQL database,
  Select email_id from source.email_id
 where email_id not in select email_id from exclusion.email_id email_id 

If that does not answer your question, could you add more information.
Is your data in two text files, python dictionaries, or what?
Good luck,
Ralph
