It's not at all clear what you're asking for. Keep in mind that the
people on this list know a lot about files, changesets, diffs,
patches, and Mercurial stuff, but very little about Oracle and exactly
nothing about your business. So ask concrete questions using terms we
understand, and we'll get somewhere.
Anyways. It sounds to me like you need to drink the Kool-Aid and
understand what a changset is. Hint: it's a snapshot of your entire
source tree at a particular moment in time. That moment is specified
by a developer running "hg commit". So if you update to changeset X,
*boom* there are all the files from that changeset. Getting diffs or
lists of files changed is actually a teeny bit harder than simply
getting the files. ("hg diff -r X:Y" gives you a diff from changeset
X to Y, and "hg status --rev X:Y" gives you a list of
modified/added/removed files between them.)
As for recording which scripts have been executed: that's not what
version control is for. Are you looking for "make" or similar tool?
(E.g. use a Makefile to drive everything. Have it touch a timestamp
file for each script executed. There's your record of what got
executed, and if you do it right, make will know what needs to be
executed, because its timestamp file is missing or stale.)
