ORA-02291: integrity constraint (%s.%s) violated - parent key not found
For Example:
First create a parent table and a child table. The child table will contain a column PARENT_ID which references the PRIMARY KEY of the parent table:
SQL> create table parent(id number primary key);Now we are going to insert a record into the parent table:
Table created.
SQL> create table child(id number, parent_id number references parent(id));
Table created.
SQL> insert into parent values(1);Now we are going to insert a record into the child table, which references the newly inserted parent record (value:1):
1 row created.
SQL> insert into child values(1, 1);Now we are going to insert a child record which references an unknown parent record (value: 2)
1 row created.
SQL> insert into child values(1, 2);As you can see, value 2 does not exist in the parent table and it generates an error. So either insert the missing records into the parent table, or provide a different value for the child record.
insert into child values(1, 2)

You are inserting data in a child column for which a parent record does not exist.
First insert a parent record
Got the same error when trying to update a 'child' table refering to its 'parent' . I understand the concept I just can't see where I'm going wrong.
Here's my tables:
create table supplier(
suppno number(6) not null unique,
sname varchar2(25) not null,
sadd varchar2(45) not null,
pcode char(8));
create table product(
pcode varchar2(6) not null unique,
pdesc varchar2(20) not null,
pqtyin number(5) not null,
pmin number(4) check (pmin > 0),
pordqty number(4) check (pordqty > 0),
pprice number(6,2) not null, /* purchase price*/
sprice number(6,2) not null, /* selling price*/
suppno references supplier(suppno));
heres my sql:
UPDATE user1.product SET suppno= 2234 WHERE pcode='CD4QPR';
heres my error:
SQL> UPDATE user1.product SET suppno= 2234 WHERE pcode='CD4QPR';
UPDATE user1.product SET suppno= 2234 WHERE pcode='CD4QPR'
*
ERROR at line 1:
ORA-02291: integrity constraint (USER1.SYS_C005436) violated - parent key not
found
Thanks in advance
And does following select return any value?
select * from suppliere where suppno=2234;
?
If not, then you will have to insert that record first.
OK i did that...the problem now is I need to update the parent and child table simulataneously..any ideas?
Generally it is a very bad idea to update the primary key of a table.
But you can look into deferable constraints if you really, really want to update the primary key together with the foreign key.
Thanks for the advice...so why is it a bad idea? what are the consequences ?
Hi ,
we are facing the "ora-02291 integrity constraint violated" error.
select child.owner||'.'||child.table_name||'.'||child.column_name||' must exist in '||
parent.owner||'.'||parent.table_name||'.'||parent.column_name
from
all_cons_columns child
, all_cons_columns parent
, all_constraints c
where c.owner='AUSER'
and c.constraint_name='SYS_C005576'
and child.owner=c.owner
and child.constraint_name=c.constraint_name
and parent.owner=c.r_owner
and parent.constraint_name=c.r_constraint_name
and child.position=parent.position
The above query is giving more than one row. 20 to 30 Forign keys.
Could you suggest please , how to resolve the issue.
Thanks.
Khalid.
you have to replace the value of the owner and constraint name with the values that were returned by your ORA-02291 error message.
This is just our test scenario, you will probably have different values
where c.owner='AUSER'
and c.constraint_name='SYS_C005576'
When you know the parent table name, you can either insert the missing parent record, or move the child record to an exception table, ...
I am executing the below query and the out put is more than one rows.
How do i proceced for this solution.
Here USDBUSR is my DB User.
select child.owner||'.'||child.table_name||'.'||child.column_name||' must exist in '||
parent.owner||'.'||parent.table_name||'.'||parent.column_name
from
all_cons_columns child
, all_cons_columns parent
, all_constraints c
where c.owner='USDBUSR'
and child.owner=c.owner
and child.constraint_name=c.constraint_name
and parent.owner=c.r_owner
and parent.constraint_name=c.r_constraint_name
and child.position=parent.position ;
And what about the (child) constraint name. If you do not include it, you will get all the foreign key constraints, but you are only interested in the one that gets violated.
Normally the constraint name is included in the error message. Can you post the complete error message you get?
1ST TABLE:-
create table departments
(department_id NUMBER PRIMARY KEY,
departent_name VARCHAR2(30));
2ND TABLE:-
CREATE TABLE employees
(EMPLOYEE_ID NUMBER PRIMARY KEY,
EMP_NAME VARCHAR2(20),
DEPT_ID NUMBER REFERENCES
departments(department_id),
MGR_ID NUMBER REFERENCES
employees(employee_id),
MGR_ID NUMBER REFERENCES
employees(employee_id),
JOB_ID VARCHAR2(15),
SALARY NUMBER);
Q:- WILE INSERTIING ROWS INTO TABLE ERROR (ORA-02291: integrity constraint violated - parent key not found) WHY? WHAT WILL BE THE SOLUTION PLZ HELP ME.
Please post the insert statements you are using.
You insert data into the employee table for which no master record exists. Either it is an unknown department, or an unknown manager
Hi ,
Am getting ORA-02291: integrity constraint (DB.C_DM_TABLEDATA_NODE_ID) violated - parent key not found error while executing my procedure. the prior error message to above is
#ORA-06512: at "DB.DM_SETNODEPROPERTY", line 42
#ORA-06512: at line 1
I can realize this would be a PK and FK relationships matter.
Please help me to resolve this issue. looking for your valuable suggestion
Thanks in advance.
