Question: What are active transformation / Passive transformations?
Answer:
Answered by kiran on 2005-05-08 09:32:14: An active transformation can change the number of rows as output after a transformation, while a passive transformation does not change the number of rows and passes through the same number of rows that was given to it as input. |
