PARTITION BY RANGE(INACTIVATED_DTSTAMP) (PARTITION DATE_082005 VALUES LESS THAN ('2005080100000000') that is not a good idea -- to have a NUMBER(16) and then compare it to a STRING compare dates to dates strings to strings numbers to numbers But that isn't the problem, and the trigger is very much part of the equation.I slimmed down the test case, made it generic and understandable easily.It took differing amounts of rows on different releases to reproduce, and it could be dependent on block size, sga, whatever (not sure, did not take it further) drop TABLE MYTAB; CREATE TABLE MYTAB ( key number, data1 char(2000) default 'x', dt TIMESTAMP default localtimestamp ) PARTITION BY RANGE(key) (PARTITION p1 VALUES LESS THAN (5), PARTITION p2 VALUES LESS THAN (MAXVALUE) ) ENABLE ROW MOVEMENT / CREATE OR REPLACE TRIGGER MYTAB_BIU BEFORE UPDATE ON MYTAB FOR EACH ROW BEGIN : := LOCALTIMESTAMP; END; / insert into MYTAB (key) select 4 from all_objects where rownum Point taken and will correct. -------- I was able to reproduce the same behaviour with your "to-the-point" test case. Tom, Let's say we have 2 partitions in a table, Partition A and Partition B.It is possible to update a partition key in all releases -- what is not possible to do prior to 8i is to update the partition key in such a fashion as to cause it to move from partition to partition.For example: [email protected] CREATE TABLE partitioned 2 ( x int, 3 y int, 4 z DATE 5 ) 6 PARTITION BY RANGE (z) 7 ( 8 PARTITION part_1 VALUES LESS THAN(to_date('01-jan-1995','dd-mon-yyyy')), 9 PARTITION part_2 VALUES LESS THAN(to_date('01-jan-1996','dd-mon-yyyy')) 10 ) 11 / Table [email protected] update partitioned set 2 z = decode( x, 1, to_date('01-mar-1995','dd-mon-yyyy'), 3 2, to_date('01-jan-1994','dd-mon-yyyy') ) 4 / update partitioned set * ERROR at line 1: ORA-14402: updating partition key column would cause a partition change But we cannot have it migrate.

Now, in Oracle8i, release 8.1 we can: [email protected] CREATE TABLE partitioned 2 ( x int, 3 y int, 4 z DATE 5 ) 6 PARTITION BY RANGE (z) 7 ( 8 PARTITION part_1 VALUES LESS THAN(to_date('01-jan-1995','dd-mon-yyyy')), 9 PARTITION part_2 VALUES LESS THAN(to_date('01-jan-1996','dd-mon-yyyy')) 10 ) 11 ENABLE ROW MOVEMENT 12 / Table created.ODI-1226: Step INT_TMPAPPS_DX_PATIENT_H fails after 1 attempt(s).

Hi Tom, I think I read in one of your book that row movement is bad design.We have scenario where last process flag(Y/N) is used to build data mart from staging.I have a table with 12 millions of records, partitioned by hash with 2 keys - col A and col B.
