Symptoms

Steps to reproduce:

1) In APEX Instance #1 , create a developer account
and assign it to one (or all) of the pre-created user groups: RESTful
Services, SQL Developer, OAuth2 Client Developer.

2) Export this workspace.

3) In APEX Instance #2, log in as instance administrator and open Manage
Workspaces / Import Workspace page.

4) Upload the export file from Step 2 and complete the import wizard — the
following error is displayed:

Execution of the statement was unsuccessful. ORA-02291: integrity constraint
(APEX_040200.WWV_FLOW_FND_GU_INT_G_FK) violated — parent key not found

This error occurs because pre-created user groups (SQL Developer, etc) do not
have the same IDs in two APEX instances.

Oracle / PLSQL: ORA-02291 Error Message

Learn the cause and how to resolve the ORA-02291 error message in Oracle.

Description

When you encounter an ORA-02291 error, the following error message will appear:

• ORA-02291: integrity constraint violated — parent key not found

Cause

You tried to reference a table using a unique or primary key, but the columns that you listed did not match the primary key, or a primary key does not exist for this table.

Resolution

The option(s) to resolve this Oracle error are:

Option #1

This error commonly occurs when you have a parent-child relationship established between two tables through a foreign key. You then have tried to insert a value into the child table, but the corresponding value does not exist in the parent table.

To correct this problem, you need to insert the value into the parent table first and then you can insert the corresponding value into the child table.

For example, if you had created the following foreign key (parent-child relationship).

Then you try inserting into the products table as follows:

You would receive the following error message:

Since the supplier_id value of 5000 does not yet exist in the supplier table, you need to first insert a record into the supplier table as follows:

Then you can insert into the products table:

ORA-02291: integrity constraint violated — parent key not found

Hi all,
I have two tables
A,B

A has primary key referenced as foreign key in B table

When I need to dleete some rows from table A.But when i tried to delete them,Iwas thrown with the error.
ORA-02292: integrity constraint (string.string) violated — child record found

So idisble the constraint from table B.
AFter that i delete the rows from table A and reserted some other rows.
But now when i try to enable the constraint,I am getting this error.
ORA-02291: integrity constraint (string.string) violated — parent key not found.

How to overcome this situation?

Answers

Error: ORA 2291
Text: integrity constraint (%s.%s) violated — parent key not found
——————————————————————————-
Cause: Attempted to insert or update values that do not have corresponding
Parent key values.
Action: obvious.

Explanation:
If you have a FOREIGN KEY constraint on a table you cannot INSERT
or UPDATE rows such that they would not have a matching PARENT
in the MASTER table.
>

Refer to metalink Doc ID: Note:19524.1

Yes you are getting the correct error .

If Oracle allows you to do this that is allow you to insert into the foreign key column without corresponding primary key then What is the purpose of enforcing primary and foreign key or parent child relationship.

In your case you can only insert into the foreign key if you have the corresponding entry in the Primary key.

If at the time of creating foreignn key, you have use «On delete cascade or On delete set null» Then you can simply delete the primary key without doping anything to the foreign key. Corresposnding values for the foreignn key will automatically be deleted or set to null.

When you enable the constraint it check existing data also. so overcome from this situation enable the constraint with novalidate option so it check for future insertion only not check existing data.

Edited by: Vivekdhiman on Oct 21, 2008 12:12 PM

The correct answer is to ensure that you DO have the parent key values — ie in the Parent table.

You would use NOVALIDATE only under exceptional circumstances — eg you are «fixing» data which was erroneous OR that you need to ignore existing rows but want the constraint enabled for future rows to be inserted after this point in time.

I have a table A which has a column x as primary key.
This column x is referenced in column y of table B.
Now as per my understanding,table A is the primary table and table B is the foriengn key table.
On deleteing from table A,i got the error child record found as x is foreign key in table B.
I disabled the foriegn key constraint in table B.
I deleted the rows from table A.
I,then reserted some rows in tbale A.
I committed the transaction.
Now I want to enable the foriegn key constraint in table B.
But I am getting parent key not found.

I have records in parent table ie table A. I am not inserting in table B[foreign key table].
I inserted in table A.
The situation is like this.

table A table B
x y
1 1
2 1
3 2
4 3
5
6
7
8

Now when i enable cforiegn key constraint in table B,I get parent key not found,but all the parent key is present in table A.
I inserted 5,6,7,8 in table A after deleting some records.

ORA-02291: integrity constraint violated — parent key not found

I have a row in parent table. I am using the same sequence from the parent table during insertion. (In fact I am getting the sequence from the drop down during insertion in plsql developer tool). Still I am getting this error.

1) Parent table’s primary key is Child table’s primary key as well as foreign key.
2) Parent table’s primary key is referred as primary key in some other child table as well.
3) But not using Supertype-Subtype relationship. Just direct reference

Can you please tell me why am I getting this error.

Answers

Because the integrity check is made immediately, and the database is temporarily inconsistent.
When you set the foreign key to be deferred it will evaluate at commit, when everything should be ok again.

I am assuming you know the fact that by this design, your Parent can have a Single Child. Hence, a change in Business req, to support multiple childs can be a headache for you.>

Can you please let me know why can’t I have more than 1 table. As I mentioned in my 2nd point, I have more than 1 child table for a same parent.

Curious to understand this.

In below test case (which I am assuming is on same lines as OP’s):
In this test case, an Integrity was made immediately and reported an error.

Can you please explain if I misunderstood your point?

I never mentioned «can’t I have more than 1 table». I was talking in terms of Records.

Say, your Parent ID 1, can possibly have more than 1 child (speaking in General terms excluding your Requirements), hence if you keep your Foreign Key as Primary Key, your Table would not allow you, would it?
I do understand that you being knowledgeable about your requirements have designed the Tables accordingly, I was just raising a concern I saw.

No Objections to your design.

If you have an error integrity constraint in Oracle on your system, I hope this guide will help you.

ORA-02291 is usually followed by “Integrity message constraint – parent not found”. This means that you tried to reference this table using the primary key, but the posts you specified did not match the primary key type.

Internet Integrity Discipline, ERROR 1:
ora-02292: (TEST.SYS_C008202) broken – child record
found

Reason
If we try to successfully delete the data from the maintables, we will first remove the mention table (child table)
When creating foreign keys, owners can specify an ON DELETE clause to indicate why rows behind the parent table are being deleted.
ON DELETE If cascading: a row from the parent table is frequently deleted, everything from the child table row related to this short period will be deleted.
ON DELETE SET NULL: and when the row of the parent row is deleted, all rows from the reference to table 1 to the row of this external content key are set to NULL.

Option 1: Correct information about table search restrictions in data

1. Find foreign table key name and column name from invalid constraint name:

col for multiple owner table names a15
Collar for a15
column name column associated with a15
primary owner pass for a10
main constraint name col a15
select for a.constraint_type,a.owner,a.table_name,b.column_name,a.r_owner "PrimaryOwner",a.All_constraints r_constraint_name "primaryconstraintname" from all_cons_columns a where
A b.CONSTRAINT_NAME = b.CONSTRAINT_NAME and a.constraint_name is OWNER 'sys_c008202';

c PrimaryOwn table_name column_name PrimaryConstrai- ————– ————— ————— ——————-R —— TEST FOREIGN TEST P_ID TEST SYS_C0082012. The best primary key of the table has now been found.
Note. Use a longer query exit constraint name and enter the enforcement information key.

col for table name a15
Branded collar for working with a15
column name column for a15
main owner pass with a10
Constraint name col is primary for a15
select a.constraint_type,a.owner,a.table_name,b.column_name,a.r_owner "PrimaryOwner",a."PrimaryConstraintName", r_constraint_name created by a, all_constraints all_cons_columns b where
A.CONSTRAINT_NAME means b.CONSTRAINT_NAME and a.constraint_name 'SYS_C008201';

C = TABLE_NAME OWNER COLUMN_NAME PrimaryOwn PrimaryConstrai- —- ———– —- ————— —— ——— TEST ——p PRIMARY IDENTIFICATION TEST3. Now you can get any of our existing rows of numbers in the reverse child that you want to delete in the main table using IN clause query.

-- I'm only giving you an example, you can also use it to delete data.
select * from TESTFOREIGN where p_id is selected (when id comes from id testprimary where = 2:1;)
