I want to export all of information from the "Columns" tab for each table in an Oracle database. I know I can do this manually (click on each table, go to the Columns tab, right click, click "Export", and create a CSV file - included in case there is a better way to do this!), but is there any way to do this without having to go to each table individually? Thank you!
Edit: I forgot to mention that I want to select tables under a specific owner.
If I understood you correctly, you'd just go to Tools menu and choose Database export. Follow the wizard, for example
On the next screen choose objects to export (you'd probably want to exclude all but tables).
The rest is <Next ... Next> and - that's all. File contents is displayed in SQL Developer, and you'll find it in target folder as well.
