Re: ORDER BY and alternate collating sequences

What are the steps?  Do you set the SQL session parameter to LANGIDSHR
in STRSQL and then run the CREATE INDEX command?  Will that then create
an INDEX that is permanently LANGIDSHR?

Yes


So then can I end my session, bring up a new session (without
LANGIDSHR), use my index and it's magically still in LANGIDSHR
sequence?

No, as there's no way for you to explicitly "use the index"

If you configure your new session for LANGIDSHR, when you do a select
and specifiy ORDER BY indexedColumn, the system will implicitly use
the LANGIDSHR index you created.

Also, that only seems to address case sensitivity.  What
tells it to use the alternate collating sequence that corresponds to
CCSID 819, for example?

Same applies AFAIK, but I've never tried it.
