File upload clarification

Question

I followed the tutorial on how to upload/download files in an application and was successful in uploading and downloading to a custom table. However, can someone explain the purpose of the DELETE statement (below) that was included for uploading into a custom table:
IF ( :P2_FILE_NAME is not null ) THEN
INSERT INTO file_subjects(id,NAME, SUBJECT, BLOB_CONTENT, MIME_TYPE)
SELECT ID,:P2_FILE_NAME,:P2_SUBJECT,blob_content,mime_type
FROM HTMLDB_APPLICATION_FILES WHERE name = :P2_FILE_NAME;
DELETE from HTMLDB_APPLICATION_FILES WHERE name = :P2_FILE_NAME;
END IF;
Do all files that are uploaded have to go through the HTMLDB_APPLICATION_FILES before it is inserted into the custom table?

Answer 1

Hi 488473,
My understanding is that since your uploaded file is copied into the HTMLDB_APPLICATION_FILES table on your behalf, you need to remove it from there when you insert it into your own table, for the sake of good housekeeping.
Hope others will confirm or correct this understanding.
