create index A and A + B and A+B+C

s197oo302Apr 3 2014 — edited Apr 3 2014

This is index question.

If you have oracle database, and have the index A + B + C colume.

You might need the index A+ B or A.

Oracle Database automatically check these case and prevent these case,

So can save disk space and prevent not using original A+ B+ C index.

What is your opinion?

If This is the right scenario we might ask oracle to make constraint on index creation.

So we only have one index A+B+C. and probibit creating A+B or A by mistake.

Give your opinion.
