About BLOB Support in Forms and Reports

Starting with release 3.1, Oracle Application Express includes declarative BLOB support to enable developers to declaratively uploaded files in forms, and downloaded or display files in reports. BLOB display and download can also be authored procedurally using PL/SQL. This section describes how to upload, download and display files, and how to manage additional file attributes such as MIME type and file name that are important for proper management of files stored in BLOB columns. Using this functionality you can easily extend your Oracle Application Express applications to manage files including images, documents, videos, and so on.
