Subject: Re: ORDER BY and alternate collating sequences

Okay, bear with me, I'm old and slow <grin>.

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?

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



Joe, I use *LANGIDSHR when I need both, case insensitivity and an
ASCII-like collating sequence (numbers before letters). Also, it allows
(AFAIK) for the correct collating sequence, regardless of the code base
used. For instance, in Spanish we have a letter that is just like a 'N'
with a tilde on top (Ñ). If I use, for instance, *HEX, the lower case
version (ñ) comes AFTER the upper case version (Ñ), because the upper case
letter corresponds (IIRC) to the # character in EBCDIC (appears before
'A'). *LANGIDSHR solves this.

The downsize is that, at least in V5R3, it seems to me that SQL tends to
use CQE instead of SQE when defining a table with *LANGIDSHR...
