Questions about this workflow
Will the catalog prove a table contains the uploaded file?
No. Table listing does not establish row-level relationships. Verify candidate tables with a query and appropriate identifiers.
What if the database has many tables?
Ask Notis to report the relevant subset using table names or descriptions available in the returned metadata.
