In my SQL ignorance I made LF = VIEW...
And I WAS thinking VIEWs as a more efficient way to access data instead of DDS.
I can now choose between:
UDTF, LF or Trigger.
Creating 200 LF over a single phisical is something I never done and I don't
know if there is a
performance issue.
UDTF, nice approach since I have a single object for multiple data libraries.
Trigger, 200 phisical files to write/update/delete
I think trigger is the light one.
Thanks
