Oracle 12c: Temporal Validity, multiple on one table - Part Deux

One of the most wonderful things of Oracle Open World are the Demo-Grounds. When you want to learn more about a certain feature, this is the place to go to. The actual developers and product managers are there to answer your questions and more!

In a previous blog I had written about Temporal Validity in Oracle 12c and whether it would be possible to have multiple validity periods on one table. You can read that blog by following this link.

Just a couple of screenshots of sqlplus+rlwrap+cygwin+console

I previously wrote that I peeped the idea about showing the session information in terminal title from Timur Akhmadeev’s screenshots, and Timur wrote:
I’m using (a bit modified) Tanel Poder’s login.sql available in his TPT scripts library: http://tech.e2sn.com/oracle-scripts-and-tools

I’m inclined to make the instance available generally but haven’t figured out the best way to do that.
