Sequnce generated column in Volatile table - response (5) by barani_sachin

Sry for pitching in middle. Correct me if my understanding is wrong :-) 
 
Bala,
    put a coalesce in the max -- SELECT coalesce(MAX(rwid),1) FROM table1. But again you wont get the same sequence when you are doing the insert for the second time as like the first time.
