Well you could use SQL in MapFile to make a JOINT beetwen two (or more)
tables if it make sense on you're data...
I'm not sure if it was really that you've asked indeed...

We already, have other projects using oraclespatial connection. You only
need to have a right configuration in you're mapfile...

An exemple:

CONNECTION "serveur/serveur at foo"
CONNECTIONTYPE oraclespatial
DATA "geometry FROM (SELECT * FROM my_table) USING UNIQUE GID"

See <http://mapserver.gis.umn.edu/doc46/mapfile-reference.html#layer>
to further informations...

Nota: some little improvements have been made quite recently on
CartoWeb3 to handle OracleSpatial support on 'id recentering' feature, 
use CVS version if you need this feature with OracleSpatial.

Nota: not use ArcSDE connect, it will only be slower with MapServer
(by a factor 2 at least)

Indeed yes, as MapServer configuration DATA source is made 
for each Layer...

No yet, we have investigated on this kind of feature, it will need
some improvement on MapServer code (imagemap). At the moment however
we're still waiting for customers who really needs this feature...

5.	how to access to the html and csv exports in the

For export CSV, you should see on the bottom of the results table
(after a query), a link to CSV export file.

For HTML, you should see a 'Print' link at the bottom of main folder.

Did you done a reset_session on you're project after client.ini 
modification ?

It should, on the other hand, many improvements 've been made on 
exportPDF, using CartoWeb CVS could be a good things...
