I have a table partitioned in DB2 V9.5 with something similar to the following:

CREATE TABLE orders(id INT, shipdate DATE, …)
PARTITION BY RANGE(shipdate)
(
STARTING '1/1/2006' ENDING '12/31/2008'
EVERY 3 MONTHS
);

Once the table is created and data has been loaded, how do I see what partitions exist so they can be detached, dropped, etc?

syscat.datapartitions?

Thats correct Nick.

To see on which filed you have your range partition defined, you can use SYSCAT.DATAPARTITIONEXPRESSION.

And to see the definition for each partitions so that you can detach some of them, you need to use "select datapartitionname,lowvalue,highvalue from syscat.DATAPARTITIONS where tabname = 'TB_TEST' with ur"
