Describe statement does not work with database link: it gives the description from the open database connection instead from the remote database.
Steps to reproduce the problem:
1] Let's assume there are two databases (db1 and db2) each having the table "tableA". TableA will be different in both databases.
1] Create a database link between these databases
2] Run desctableA@databaseLinkNamein the code editor
3] The table displayed is the one from the open database connection instead that from the remote database.
Waiting for fix in a future release of SQL Navigator For Oracle.
