Can any one explain what the "R.O" mean when we generate a SQL expression:

ro.png

...and does Adobe Campaign generate the "R.O" be default in every SQL interpretation.

Thank you.

Thank you so much for the reply. In addition, what does "RO" stand for?

And is it best practice of RDMS to use "RO" as an alias?
