Unique Constraint Violated?
Mar 26, 2007
From a step by step instructions I'm asked to put the following into sql*plus:
CREATE TABLE Lab2Lecturer
(staffNO VarCHAR2(10) NOT NULL,
title VARCHAR2(3),
fName VARCHAR2(30),
[code]...
Then the following:
INSERT INTO Lab2Lecturer
(staffNO, title, fName, lName, streetAddress, suburb, city, postCode, country, lecturerLevel, bankNO, bankName, salary, workLoad, researchArea)
VALUES
('1000', 'Dr', 'Johanna','Santoso',
'3 Robinson Av', 'Kew', 'Melbourne', '3080', 'Australia', 'C', '1000567237', 'CommBank', 65000.00,1.0, 'O-R DB');
and finally,
INSERT INTO Lab2Lecturer
(staffNO, title, fName, lName, streetAddress, suburb, city, postCode,country, lecturerLevel, BankNO,bankName, salary, workLoad, researchArea)
VALUES
('1000', 'Dr', 'Justine', 'Martin', '6 Algorithm AV', 'Montmorency', 'Melbourne', '3089', 'Australia', 'D', '1000123456', 'CommBank', 89000.00, 1.0, 'CBR');
when I try entering in the second one I get an error 'unique constraint violated'.So whats wrong exactly?

My DB version is
BANNER
----------------------------------------------------------------
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi
PL/SQL Release 10.2.0.4.0 - Production
CORE 10.2.0.4.0 Production
TNS for Linux: Version 10.2.0.4.0 - Production
NLSRTL Version 10.2.0.4.0 - Production
These error codes I'm getting in production.First of all, I've no duplicates present in that table for which this error has been raised.I've checked the index and related columns as well. NO DATA is there.So NO CHANCE for unique constraint violation.
SELECT * FROM ORDER_OCC_REQUISITION_X_REF WHERE LAB_ORDER_OCC_TEST_ID IN(SELECT LAB_ORDER_OCC_TEST_ID FROM LAB_ORDER_OCC_TEST WHERE LAB_ORDER_OCC_ID = 7944858);
no rows selected
Now when I'm trying to insert one row inside this table I'm getting this error, as you are seeing no records for this occurrence_id.
SELECT * FROM USER_INDEXES WHERE INDEX_NAME = 'ORD_OCC_REQ_UQ_TEST_IX_04';
--ORDER_OCC_REQUISITION_X_REF (Table name)
--MERGE_DT, LAB_ORDER_OCC_TEST_ID, TEST_ID, ACTIVE_YN (columns for the index 'ORD_OCC_REQ_UQ_TEST_IX_04')
As you can see there is no data then this error should not be raised. Update procedure.
/*******************************************************************************************************************

[Code] ......
After i check data in all_indexes table, i have found some old data which are belongs to 2008 and 2009. The sample as below:-
OWNER INDEX_NAME LAST_ANALYZED
SDS1PK_ACTION 31-OCT-09 07:04:49
SDS1AK_ACTION 31-OCT-09 07:04:49
SDS1PK_COND 31-OCT-09 07:04:50
SDS1AK_COND 31-OCT-09 07:04:50
SDS1COND_FK1 31-OCT-09 07:04:50
SDS1COND_FK2 31-OCT-09 07:04:50
is it the problem due to the old data not remove from the all_indexes table ?.. if YES is it I have to delete the old data manually from the all_indexes table ?

I got this error message in my replication environment.
ORA-12012: error on auto execute of job 2182370
ORA-12008: error in materialized view refresh path
ORA-00001: unique constraint (TE.S_TE_MTH_DBASE_SALES_INFO_A_U1) violated
ORA-06512: at "SYS.DBMS_SNAPSHOT", line 189
Materialized view and Base table having only one unique index. There are no referable constraints in my base table. Because source table not refer any other tables.
Even; materialized view log created using rowid because there are no primary key constraints in my base table.When I manually refresh materialized view I got the below error message
ORA-00001: unique constraint (TE.S_TE_MTH_DBASE_SALES_INFO_A_U1) violated
How it's possible? Because there is parent/child relationship in my source table and there is no way to enter duplicate records it's unique index.

i have a table for example :
CREATE TABLE RMD_2
(
"RMD_ID" NUMBER(10,0) NOT NULL ENABLE,
"ABB" VARCHAR2(16 BYTE),
"ACT_IND" VARCHAR2(1 BYTE) NOT NULL DISABLE,
CONSTRAINT "RMD_2_C1" CHECK (act_ind IN ('Y', 'N')) ENABLE
)
for column ACT_IND their is a check constraint RMD_2_C1 it should only accept either Y or N.
but, when ever i am inserting other values other than Y or N it is accepting it should not accept and it should have to give error message ORA-02293- : check constraint violated.
but it is not happening,it is accepting all other values even NULL value also.my requirement is this column should only accept either Y or N and it should not accept other values.

Each time when I import an application into my workspace in local 10g XE using the APEX 4.2 Application Builder, I get the "ORA-02291, constraint wwv_flows_fk violated..". The application I whant to import was originally exported from [URL]. I found out, that it has to to with wwv_flow_application_install.get_workspace_id in the installation script, which obviously returns NULL and not my current workspace id as I suppose it should. I replaced wwv_flow_application_install.get_workspace_id by '<my worskspace id>' and then the import does work.

ORA-00001: unique constraint (ODBA.DF_U2) violated
Searching metalink, its related to bug 6014994 and the proposed workaround is to delete the constraint:
Cause:
Dropping a datafile from a tablespace followed immediately by adding
another datafile to the same tablespace will cause this Unique Key violation.
Taking a RMAN debug trace will show the file# related to the error
This is reported as bug <<6014994>> Unpublished on Metalink and fixed in 11g
RMAN RESYNC catalog signals DF_U2 violated constraint when a file# is reused in
the same tablespace
Solution
WORKAROUND: Drop df_u2 constraint
where can I delete the constraint, is it possible to do in RMAN or in the target instance?

I've set up Oracle Streams replication between multiple N-way zones like this:
CODE------------------------------
Nway1 |Intersect| Nway2
DB1 --|-- DB3 --|-- DB5 DB1, DB2, DB3, DB4 - N-way1
| | | | | DB3, DB4, DB5, DB6 - N-way2
DB2 --|-- DB4 --|-- DB6 DB3, DB4 - intersection zone
| |
-------------------------------
Physically DB1 .... DBN connected sequentially, so I want to prevent segmentation if some DB is unaccessible, but at the same time fight unneeded redundancy which uses too much link bandwidth to send N-1 LCR-s to all members of a single N-way group (so I want to split one big N-way zone into smaller ones and sequentially connect them into chain - it significantly reduces load on link if N is big enough (>10)). Also I want to have 2 DB in intersection zone to prevent single point of failure.
This scheme has one drawback - if change originated on DB3 or DB4, then it will be propagated (more correctly - applied and captured again) to DB5 and DB6 by both DB1 and DB2 (and, as far as I know, I have no means in capture rules to detect state of DB2 from DB1 and vise versa), so on DB5 and DB6 I get:
CODEORA-00001: unique constraint (DUMMYUSR.UNIQUE_RECORDS) violated error
I've set up standard conflict handler for apply process:
CODE
declare
cols DBMS_UTILITY.NAME_ARRAY;
begin
cols(1) := 'no';
cols(2) := 'name';
cols(3) := 'ddate';
dbms_apply_adm.set_update_conflict_handler(
object_name => 'DUMMYUSR.DUMMYTBL',
method_name => 'DISCARD',
resolution_column => 'no',
column_list => cols
);
end;
but it seems that it does not handle uniqueness conflicts. What is the best way to handle uniqueness conflict (is there a better way than to write custom error handler) and how serious is the impact on insert performance of having unique constraint and corresponding error handler. (In real world I will have to deal with tables with metainformation and without any keys).
Also, how to proceed with no error or raise exception from apply error handler with error that caused this handler to run? In oracle docs I can find only example that modifies LCR and runs lcr.EXECUTE(TRUE), but what to do if I don't want to reexecute LCR, but merely check error code and propagate error if it is not ORA-00001?

I have 3 columns in a table: colX, colY, colZ.
Trying to find a way to prevent duplicates with these, but only if colX is not null.
For example, if there are already values for: colX = 1, colY = 1, colZ = 1
then:
Allowed: colX = null, colY = 1, colZ = 1
Not allowed: colX = 1, colY = 1, colZ = 1
I can't create a unique constraint on these columns because there are many null values for column colX, and as mentioned, when colX is null, colY and colZ can be any values.
I also tried using a before insert trigger to find duplicates before posting and raise an error if found, but this causes an ORA-04091 mutating error since the trigger in the table is referencing itself to check for duplicates.
Also, I know there is something called a function based index, but I cannot use those with my code, so I need another solution if possible.

about the functionalty w.r.t. unique constraint and Distinct clause. Below is the example which is confusing me lot.
--Below statement will create table and unique constraint
Create Table A (A Varchar2 (10) Unique);
Insert Into A Values (Null);
Insert Into A Values (1);
Insert Into A Values (2);
[code]...
If we are saying each null value is having a unique value, then why oracle distinct showing records.

I have a table where I want user to fill in unique values for a field which is easy to do.
Problem is sometimes the values can be null so an ordinary unique constraint does not work because multiple null records. Is there a way of validating only non null values to ensure all data entered that is non null is unique?

I have created a table below, my TL asked me to create a local unique constraint for the below table.
I went through all sites and could not find the correct solution, how to create LOCAL UNIQUE CONSTRAINT ON SUB PARTITION TABLE and LOCAL UNIQUE INDEX ON PARTITION TABLE. Creating Local Unique constraint should take care of creating local unique index creation.
Unique key columns are DET,GDS,ARRIVE_DT
CREATE TABLE SUB_PAR_TAB
(
ID VARCHAR2(100) NOT NULL,
REGION VARCHAR2(40) NOT NULL,
SOURCE VARCHAR2(80) NOT NULL,
DET VARCHAR2(80) NOT NULL,
GDS VARCHAR2(40) NOT NULL,
ARRIVE_DTDATE,
SYS_SOURCE VARCHAR2(25) ,

I have two different java process trying to insert in the same time in the same table for the same trade. The structure of the table Report is
create table report
( TRADE_ID NUMBER,
VERSION NUMBER,
MESSAGE_TIME TIMESTAMP)
There is a unique key on (TRADE_ID and VERSION) So if a new trade_id is inserted, the version is set to 1 and the second becomes 2 and so on. The version is calculated as last version of the trade_id ie. version + 1. It was woking fine till a new Java process was build that fired inserts through ten different java instances at the same time resulting in unique key error. So in detail what is hapenning is if three records of trade_id's comes in at the same time it should allocate versions in a first come first serve basis and there should be three versions of trade id 1,2 and 3. Now due to the multiple instances they all seems to get fired at once and all ending up with version one and thus resulting in unique key constrain error while trying to insert into the table.

i have a problem that i have created a table named PROJECT and structure is like-
CREATE TABLE PROJECT
(
id VARCHAR2(250 BYTE) NOT NULL,
NAME VARCHAR2(250 BYTE) NOT NULL,
COMPID NUMBER NOT NULL,
[code]...
and this table is created in some number of different database then i want to delete the not null constraint of "id" column and there is 3 not null constraint in my table and i didnot gave name at the time of creation, so we cant delete it by its name in the script because there will be different name in another database for the same constraint. i want to make a script to delete the not null constraint because it is the part of my script.
how should i get proper information for deleting the constraint. and i used "user_constraints" but it shows same information for the all three "not null" constraint.

custID Number(5),
orderSource Number(2),

How am I suppose to enter this constraint value into the creation of this table?

I have three tables:
A {op_id, op_name, .}
B {b_id, op_id, supplier_id, .}
C {c_id, op_id, op_id2, supplier_id, relation, .}
Table B and C have op_id which is foreign key from table A. In table A op_id is primary key, in table B b_id is primary key and in table C c_id is primary key. In table B supplier_id and op_id may have duplicate records. Now I want to add constraint so that if I delete records from Table B for op_id and if a relationship record exists for op_id in table C then it should not allow me to delete. Is it possible through referential integrity constraint ?

Below is the step i gone through:
1) CREATE TABLE mutu (id NUMBER, text VARCHAR2(20));
2) INSERT INTO mutu SELECT rownum , 'mutu' FROM dual CONNECT BY LEVEL <= 10000;
3) Insert Duplicate row.
INSERT INTO mutu VALUES (42, 'DUPLICATE');
4) COMMIT;
5)Create a NON-UNIQUE INDEX's CONSTRAINT as below.
ALTER TABLE mutu ADD CONSTRAINT mutu_pk PRIMARY KEY(id)
USING INDEX(CREATE INDEX mutu_pk ON mutu(id)) ENABLE NOVALIDATE;
6) Insert Duplicate row.
INSERT INTO mutu VALUES (42, 'DUPLICATE');
7) ERROR at line 1:
ORA-00001: unique constraint (SYS.ZIGGY_PK) violated
Why it shows the error. Even though I had created a NON-UNIQUE INDEX's Constraint only.
