I am not sure why but I just installed SQLdeveloper 32 bit (3.0.0.4). When I click to expand the tables/views/indexes or etc it displays nothing at all!
But when I do the following:
SELECT owner, table_name
FROM dba_tables
I see the list of tables and I have read access to these tables since I can do a select * from anytable and data shows. Any thoughts?
