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?
The SQL Developer tree shows you what objects you own, not what objects you have access to. If you want to see the objects that you have access to that are owned by other users, you would need to navigate to the "Other Users" branch of the tree, then the user that owns the table, then the "Tables" branch.
Add select privilege to all_objects/user/ojects in the db user
Launch SQL Developer as administrator
