What is the function in Transformer stage can act as Rank
Function in oracle
Answer Posted / nish
answer:
there is no function equivalent to that.
Rank is mostly used as an analytic/aggregating function in oracle and takes 2 columns for arguments.
Transformer stage performs transforming operations for later analysis ,doesnt directly perform analytic functions.
The closest stage would be an sort- aggregator stage for RANK.
Please remember that not all interview questions have a definitive answer.
This one tests confidence of how much you really used transformer stage.
