Question

My table definition

CREATE TABLE PROVISION_HIST
(
      card_nbr             number(9) primary key,
      provision_loc_cd          varchar2(2),
      start_ts                  timestamp(6),
      end_ts                    timestamp(6),
      last_updt_ts              timestamp(6),
      provision_meta_data       xmltype,
      unprovision_meta_data     xmltype,
      PERIOD FOR user_valid_time (start_ts, end_ts)
)
PARTITION BY RANGE (end_ts)
(  
   PARTITION PROVISION_HIST_P0 VALUES LESS THAN (TO_DATE('10-01-2014', 'MM-DD-YYYY')),
   PARTITION PROVISION_HIST_P1 VALUES LESS THAN (TO_DATE('11-01-2014', 'MM-DD-YYYY')),
   PARTITION PROVISION_HIST_P2 VALUES LESS THAN (TO_DATE('12-01-2014', 'MM-DD-YYYY')),
   PARTITION PROVISION_HIST_P3 VALUES LESS THAN (TO_DATE('01-01-2015', 'MM-DD-YYYY'))
);

CREATE UNIQUE INDEX provision_hist_pk 
   ON PROVISION_HIST (card_nbr, provision_loc_cd, start_ts);

I JUST NEED TO INSERT SOME DUMMY DATA FOR TESTING. SO I USED

INSERT INTO provision_hist (CARD_NBR,PROVISION_LOC_CD, START_TS,END_TS,LAST_UPDT_TS,PROVISION_META_DATA,UNPROVISION_META_DATA)
VALUES (4444,'lx',to_timestamp( '03/18/2012 02:35 AM', 'MM/DD/YYYY HH:MI AM'),to_timestamp( '12/01/2014 02:35 AM', 'MM/DD/YYYY HH:MI AM'),current_timestamp(6),'<Warehouse whono="200"><Building>Leased</Building> </Warehouse>','<Warehouse whono="200"> <Building>Leased</Building> </Warehouse>'
);

ORA-02290: check constraint (USER_VALID_TIME793C79) violated

Any help would be great.

Thanks.

Answer 1

You have just displayed a variation of a known bug associated with Oracle 12c's temporal validity feature, Bug 18195286 : ORA-2290 ON INSERT INTO TABLE WITH TEMPORAL VALIDITY .

Specifically, when one alters or creates a table with the PERIOD FOR clause, a constraint is created to validate the dates for the period:

PERIOD FOR user_valid_time (start_ts, end_ts)

The constraint created can be displayed by querying user_constraints. It will show this:

SELECT search_condition
FROM user_constraints
WHERE table_name = 'PROVISION_HIST'

Results in the constraint:

(start_ts < end_ts) and (VALID > 0) 

Your insert statement throws an error with this constraint.

Kim Berg Hansen identified this earlier, I am just citing the actual bug. This is identified as being fixed with version 12.1.0.2.

Just by looking at the Insert part the AM of the to_timestamp is bothering me. How about at least taking out AM because it looks like in http://www.techonthenet.com/oracle/functions/to_timestamp.php , they don't do that. So first lets take out that. Maybe you also want to change FOR to AS. And it seems that user_valid_time is a function because of the parameters it takes in, so I will recommend finding this function and checking its implementation.
