Toplink Delete Integrity Constraint.

I have been beating my head against my key board for a few days on this.
Note: Names of packages/class names/DB info altered because I am paranoid.
Excerpts from my toplink log....

Somehow generates these delete statements..

DELETE FROM T_CHILD_CLASS WHERE (ID = 588504)
DELETE FROM T_CHILD_CLASS WHERE (ID = 629458)
DELETE FROM T_CHILD_CLASS WHERE (ID = 588850)
End Batch Statements
Obviously this error is generated.

I think this has something to do with Toplink trying to order my deletes in a way they think they should be and ignoring the way I asked Toplink to delete the objects...
Any help with this would be greatly appreciated.

The ChildClass class is not privately owned. Obviously the FK Constraints are set up.
The problem may be because that the ParentClass can share the same ChildClass. ChildClassesA does not contain the same objects in ChildClassesB.
unitOfWork.deleteAllObjects(parentClasses);
unitOfWork.deleteAllObjects(childClassesA);
unitOfWork.deleteAllObjects(childClassesB);
I have tried the line below from the 10.1.3 user guide with no success. getDescriptor() is deprecated so I am not sure why it is in the user guide. Is there a better way to do this? I would think that you would not have to do this at all if you have FK constraints set up and you specify that you want to delete all the parents BEFORE you even start deleting the child classes.
session.getDescriptor(ParentClass.class).addConstraintDependencies(ChildClass.class);

Cannot Delete Content Areas without getting Integrity Constraint Issues

When I try to delete an unused Content Area by issuing the command:
Delete from wwsbr_sites$ where id = <value>;
I get the following error:
ORA-02292 - integrity constraint violated child record found.
How can I delete these entries and cascade through the what looks like maybe some 100 other child tables?

We have done that...Deleted a Content Area through the Navigator...But the Content area still exists, there is nothing in there, but it is still there, it is like a ghost. And when you query the wwsbr_sites$ table
where ID for that Content Area is still there.

Integrity constraint child record found

TopLink Version: Oracle TopLink - 11g Release 1 (11.1.1.0.0) (Build 070323)
I may be going crazy here, but I keep getting an integrity constraint when I try to delete an object that has 1:M relationship (Resource 1:M Attribute):
Internal Exception: java.sql.SQLException: ORA-02292: integrity constraint (WEBCENTER.WP_RELATIONSHIP_RES_FK) violated - child record found
The child object attribute is set to "Private Owned", and there is an FK from the child table to the parent table in the database (this is where the integrity constraint violation is coming from).
I query for the Resource, register it in the unit of work, call UOW.deleteObject(resource), and then call UOW.commitAndResume(). TopLink is making a sql call to delete the Resource, but it does not first delete the privately owned Attributes which results in the FK violation.
It should delete the child records first, right?
In addtion to having the attribute set to "Private Owned", I also have set:
Batch Reading
Use Indirection
Transparent
Not sure if that makes a difference.

Use a trigger. Example:
CREATE OR REPLACE TRIGGER update_parent_chilren
BEFORE UPDATE OF pkey_column ON parent_table
FOR EACH ROW
BEGIN
UPDATE child_table
SET fkey_column = :NEW.pkey_column
WHERE fkey_column = :OLD.pkey_column;
END update_parent_children;

Database Integrity Constraints

Hi All
Is there any DI API component or any other solution to handle the Database Integrity Constraints (Relationships): between parent table and child table. when I delete a record from parent table referenced by some records on a child table, I want to denied this action
can I get a solution ?

Hi Juha
I develop an Add On, for this case, I must create my ouwn user tables:
I have a User MasterData Table_1 (MD_Table1),
and a User MasterData Table_2 (MD_Table_2)which referenced to the first one,
(MD_Table_2.LinkedTable = "MD_Table_1")
On these Tables, I have create UDOs
UDO.CanDelete = SAPbobsCOM.BoYesNoEnum.tYES
UDO.ObjectType = SAPbobsCOM.BoUDOObjType.boud_MasterData
UDO.TableName="MD_Table_1"
UDO.Add()
UDO.CanDelete = SAPbobsCOM.BoYesNoEnum.tYES
UDO.ObjectType = SAPbobsCOM.BoUDOObjType.boud_MasterData
UDO.TableName="MD_Table_2"
UDO.Add()
The problem is:
When I delete a record (rec_1) from the first Table (MD_Table_1)which is referenced to a record (rec_2) of the second (MD_Table_2), the action is accomplished successfully. in spite of rec_1 is referenced to rec_2 .

Automated Solution for Integrity Constraints?

Here is the situation. I have a parent table with child rows in LIVE. A workspace is then created, and another child is added to one of the parent rows in live. Another workspace is then created, and the parent row for the first workspaces child is deleted. The user tries to merge the second workspace to LIVE, which fails with a ORA-20237 error (expected).
How do I in an automated fashion, determine what row(s) in what workspace(s) are causing the error workspace merge? This is on 10gR2.
Integrity constraint violations do not show up in the CONF views, so that doesn’t help. I need to be able to eliminate the conflicts in an automated fashion, providing notice to the owners of the workspaces that they need to go revise the parts that were forcefully removed. But to do that, I need to know how to locate the issues causing the problem so I can build a package to do this, hands off.
Example script:
SQL> create table test_parent (pk number not null, name varchar2(50),
2   CONSTRAINT test_parent_ndx PRIMARY KEY (pk));
Table created.
SQL> create table test_child (pk number not null, fk number, name varchar2(

Hi Amit,
The merge operation does result in the deletion of the row from both LIVE and the child workspace. However, this would cause the child table in the other (non-merged) workspace to have data without a corresponding parent row. We can not allow this, and so raise a referential integrity constraint violation. It is also not a conflict, as conflicts are always for rows with the same primary key, not for business conflicts or constraint violations. In the example, the inserted row in the child workspace was for a primary key that was unique within all workspaces, and so no conflict violation would be raised.
The reason it works for a non-CR workspace, is that the parent table row is still visible from the other workspace as it was not automatically deleted.
You can use the DIFF view(with SetDiffVersions) or the MW view(with SetMultiWorkspaces) to determine which rows were deleted from the parent table that you are merging. This information can then be used to find the other workspace/savepoint that is causing the violation and fix it. This could be done by removing the child row or inserting/updating the parent row prior to the other workspace being merged.

Error Message for Integrity Constraint

Hi,
I have a table with called TMREF_MEDIATION_DATA_TREATMENT and one called TMREF_UOC_CRITERIA_MAPPING. There is a foreign key constraint and the TMREF_UOC_CRITERIA_MAPPING
table has the UID column from the other table in it. When I select delete form TMREF_MEDIATION_DATA_TREATMENT I get an error as expected:
ORA-02292: integrity constraint (MRS_DEV.TMREF_UOC_CRIT_TO_TREAT_FK2) violated - child record found
Error
Unable to process row of table TMREF_MEDIATION_DATA_TREATMENT.
OK
But is there any way that I can make this error more user friendly? I do not want it to delete if there is a child record - it must just warn the user.
Thanks.

You could use this method:
http://apex.oracle.com/pls/otn/f?p=31517:185
which is in the page process. However, you could also create a validation, which will fire before the process is run and check the same.
Entering an invalid number will violate the constraint (the column is a number column) and this will then call the exception INVALID_NUMBER. You may also declare the constraint exception using
child_record_not_found EXCEPTION;
PRAGMA EXCEPTION_INIT (child_record_not_found, -02292);

How to find the table name on which integrity constraint not found

Hi All
How to acheive this
I have a lot of tables with lot of primary key - foreign key
relationship.
In plsql
when any inserts happen in the child table & the corresponding row is not present in the parent table, we get an exception
ORA-02291: integrity constraint (user1.ppk) violated - parent key not found
On this exception , in the exception block i want to trap teh name of the parent table on which the primary key for the particular child table was not there
Is it possible to retrieve the parent table in this way. I am looking for a generic plsql code block which can help to acheive this

SQL*Loader and integrity constraints

I am running into trouble with integrity constraints in my SQL*Loader script runs. Should I be going up to unix and removing the constraints from sqlplus, then asking the wizard to reinstall them after the data load? Is this documented somewhere? I can't find it. Sorry for asking such a basic question.
Thanks,
Ann Cantelow

Hi,
Your approach is correct.
Create tables first
Move data via the scripts
Create contraints, indexes, primary keys

How to create business rule for 'Integrity constraint - child not found'

Hello, I am using JDeveloper 11.1.2.3.0.
When an integrity constraint is violated an error message coming from database is displayed in my application. In this case is the error "integrity constraint (TableName) violated - child record found "
How can I personalize the error shown in this case? I tried with EO business rules but I couldn't find this key, only "Key exists" or "UniqueKey".
Can anyone help?

Differences between trigger and Integrity Constraints

waht are the differences between trigger and Integrity Constraints

waht are the differences between trigger and Integrity ConstraintsConstraints are to be preferred:
"Declarative Ease
Define integrity constraints using SQL statements. When you define or alter a table, no additional programming is required. The SQL statements are easy to write and eliminate programming errors. Oracle controls their functionality. For these reasons, declarative integrity constraints are preferable to application code and database triggers. The declarative approach is also better than using stored procedures, because the stored procedure solution to data integrity controls data access, but integrity constraints do not eliminate the flexibility of ad hoc data access.
Centralized Rules
Integrity constraints are defined for tables (not an application) and are stored in the data dictionary. Any data entered by any application must adhere to the same integrity constraints associated with the table. By moving business rules from application code to centralized integrity constraints, the tables of a database are guaranteed to contain valid data, no matter which database application manipulates the information. Stored procedures cannot provide the same advantage of centralized rules stored with a table. Database triggers can provide this benefit, but the complexity of implementation is far greater than the declarative approach used for integrity constraints."

Hi,
as you say your Apex instance is new - does the workspace you exported the application from exist on your new apex instance? Probably not. You could try to set the appropriate one using the API like this:
exec wwv_flow_api.set_security_group_id(p_security_group_id => apex_util.find_security_group_id(p_workspace => 'XYZ'));This still requires that you already have created the workspace.
Is there a reason why you don't import the application with the workspace import?
