Display editors
Once you have expanded an object type node in the Connections navigator, selecting any object in that node opens a window of tabs, called display editors, which define the object. Each editor displays a data grid of details describing the selected object. These are based on queries against the data dictionary and you can get the same results by writing the SQL yourself.
The number and types of editors displayed will vary depending on the object or database that you are connected to. If you are connected to Oracle Database 11g or above, then an additional Flashback editor displays with the other table display editors.
Note
The Partitions tab is permanently displayed from SQL Developer 2.1.
