You are honored like a god here (in SAP HANA section) - so i would call it "supernatural" instead of "lucky"

Ah ok i get it now. It is pretty interesting that it seems like the compound column is stored physically and not "created on-the-fly" like a virtual column in the RDBMS that i am aware of.
Thanks.
