When I try to connect to Oracle database I encountered the following error:
The given key was not present in the dictionary.
at System.Collections.Generic.Dictionary`2.get_Item(TKey key)
at Quest.Toad.Db.ConnectionProxy.Implementation.ConnectionImplementation.GetObject(Int32 objectId)
The application cannot show database tables and then asks me to close it.
windows 7 64 Bit, TDP 18.104.22.1685 Pro edition.
I would appreciate some help.
