AW: Removing table partition

Thanks Jeff ... I would of course have to drop existing constraints and indexes, then recreate them all afterwards too.

Guess I have to fess up as well, it isn't one table, but around 400, albeit quite small (ranging from a few dozen to a few million rows). I will likely script it all as a last resort. I am just a little aghast that implementing partitions on existing tables appears to be natively supported whereas going the other way ... you cannot, it's a one way road.

DBMS_REDEFINITION seemed like an obvious port of call too, but the functionality I seek doesn't seem to be on offer. Am I missing something?
