I researched and saw a case like this:
SELECT article_id, file_id, revision, source_file_id, file_name, original_file_name FROM public.article_files
where article_id = 5871
ORDER BY file_id ASC
article_id | file_id | revision| source_file_id| file_name | original_file_name
5871 | 12665 | 1 | 12664 | 5871-12665-1-CE.pdf |5871-12664-1-SM.pdf
5871 | 12668 | 1 | ‘null’ | 5871-12668-1-PB.pdf |Texto Eustáquio.pdf
Could I set source_file_id = file_id for all records?
