Video : Collation and Case-Insensitive Queries in Oracle Database

Today’s video is a run through the Collation functionality introduced in Oracle Database 12c Release 2 (12.2).

If videos aren’t your thing, you can find a lot more information about this subject in my article here.

The cameo in today’s video is Kim Berg Hansen. 🙂

Collation and Case-Insensitive Database in Oracle 12.2

A little while ago Jeff Smith asked me if I had done anything with the collation functionality in Oracle Database 12c Release 2 (12.2). At the time my response was I was letting it stew a little before I released anything about it.

For some functionality the manuals contain a lot of information, but it’s not always obvious how much you will really care about. The collation functionality is exactly like that. You can get bogged down in some quite heavy stuff, or you can give some basic examples to point people in the right direction and let them go further if they need to. That’s the route I took with this article.

I think this will be a game-changer for some applications. If you’re a MySQL user you are probably laughing now about how long it’s taken Oracle to catch up. 🙂

As always, you have to approach this stuff with a little caution. Making a change that affects every query against some data for comparisons and ordering is rather dangerous. I’m not sure how quickly, if ever, I would be considering a switch across to this for my actual table segments, but I can certainly see how some views or materialized views could be put to good use really quickly.

It will be interesting to see how this is recieved.
