RE: Create View

[Marco Facchinetti <facchinetti@xxxxxxxxx>]

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
Marco
