Thanks Shripal, I was reading this clause in Cursor topic, It's become quite easy to see it practically. There is similar topic of clause "WHERE CURRENT OF" . Please explain that also. Also i can see you are running Oracle in linux. PLese share video how to install Oracle in Linux. Presently i am working on windows.
Suggestion is : Please speak little bit louder..:)
