DB2 LUW 8.1 fixpak 14
Linux Red Hat AS
I'm trying to get the maximum value of a sequence. Because of the way
the sequence is used (on several tables comprising a fat view), its too
expensive to do the usual
select max(<col>) from <view;
Is there some way for the system catalogs or some trick to get me the
maximum value of the sequence?
Note that I'm on DB2 LUW 8.1 fixpak 14. There's apparently some
sequence highwater column in v9, but I don't think I have it.

You can see the next value (that would have been assigned), which is
presumably one more than the present "maximum value" by running the
following:
VALUES NEXTVAL FOR <YOUR_SEQ_SCHEMA.YOUR_SEQ_NAME>;

If you don't have it on your version look in SYSIBM.SEQUENCES

Serge: thx for reply.
There is no SYSCAT.SEQUENCES.NEXTCACHFIRSTVALUE,
and SYSIBM.SEQUENCES does not exist....???
Any other ideas?
