I get asked questions a lot about accessing BLOBs once they’re in the database. And that’s led to quite a few posts here on the subject: Viewing BLOBs as pictures Viewing BLOBs in External Editors (PDFs, spreadsheets, etc.) Including BLOBs in your PDF reports But…

Updated 8 August 2023 This feature has been removed, instead you can use the utPLSQL extension for SQL Developer. Wait, what is utPLSQL?
