After getting my new Mac, I had to reinstall all my apps, including SQL Developer. That's when I started to run into this issue - every time I tried to expand a table to see its structure, I would get the following error -
 Error
ORA-00904: "ORA_ROWSCN": invalid identifier


My Messages Log started to fill up with these and of course I couldn't see the structure of the tables like I wanted to.

Turns out fixing this problem is easy. Open up the SQL Developer Preferences, then navigate to Database > Object Viewer. Untick the box that says Use ORA_ROWSCN for DataEditor insert and update statements.

That's it! After this change SQL Developer should work as expected.
