Unanswered: How partition of table space works in DB2?
I want to know how the keys in the partition of a table works.
I have 6 keys and all are used for partition, i have around 30 partitions based of different criteria.
All partitions have ending at (key values), it does not have starting at (key values).
For example CASE1;
partition 1 ending at (ABC,ABCB,25-10-2015)
partition 2 ending at (ABC,ABCD,25-10-2015)
partition 3 ending at (ABC,ABCD,20-11-2015)
partition 4 ending at (ABC,ABCF,25-12-2015)
i am inserting data of (ABC,ABCC,28-10-2015) TO WHICH PARTITION WILL THIS GO?
For example CASE2;
partition 1 ending at (ABC,ABCB,25-10-2013)
partition 2 ending at (ABC,ABCD,25-10-2014)
partition 3 ending at (ABC,ABCF,20-11-2015)
partition 4 ending at (ABC,ABCH,25-12-2015)
i am inserting data of (ABC,ABCC,28-11-2015) TO WHICH PARTITION WILL THIS GO?
Please explain me to understand the hierarchy and how key depends on inserting values to specific partition.

Is this so hard to try?
create table test_part (key1 varchar(10), key2 varchar(10), key3 date) partition by range (key1, key2, key3) ( part p1 starting (minvalue, minvalue, minvalue) ending ('ABC','ABCB','2015-10-25') , part p2 ending ('ABC','ABCD','2015-10-25') , part p3 ending ('ABC','ABCD','2015-11-20') , part p4 ending ('ABC','ABCF','2015-12-25') ) in userspace1; insert into test_part values ('ABC', 'ABCC', '2015-10-28'); select d.datapartitionname, p.* from test_part p, syscat.datapartitions d where d.tabschema=user and d.tabname='TEST_PART' and d.seqno=datapartitionnum(p.key1);Regards,
