Ora 02292 FRM 40735

Question

I have a form with two data blocks. There is a foreign key relationship between the two tables. Let me give an example. If I have two tables with the following primary keys:
Folder (folder_id);
Message (message_id, folder_id);
I want to write a trigger that will update the key in Message:
BEGIN
UPDATE Message
SET folder_id = 8432
WHERE sender = :VARIABLE;
END;
If I try this, I get the ora 02292 FRM 40735 error message within the Forms runtime. I know that it has to do with the primary key integrity constraint, which is obvious. Is there a way around this?

Answer 1

I treid the following:
CREATE TABLE FOLDER (FOLDER_ID NUMBER NOT NULL, FOLDER_NAME VARCHAR2(20));
ALTER TABLE FOLDER ADD CONSTRAINT FO_PK PRIMARY KEY (FOLDER_ID);
CREATE TABLE MESSAGE(MESSAGE_ID NUMBER NOT NULL, FOLDER_ID NUMBER NOT NULL, SENDER VARCHAR2(30));
ALTER TABLE MESSAGE ADD CONSTRAINT ME_PK PRIMARY KEY (MESSAGE_ID,FOLDER_ID);
ALTER TABLE MESSAGE ADD CONSTRAINT ME_FO_FK FOREIGN KEY (FOLDER_ID) REFERENCES FOLDER (FOLDER_ID);
INSERT INTO FOLDER (FOLDER_ID, FOLDER_NAME) VALUES (1, 'Folder 1');
INSERT INTO FOLDER (FOLDER_ID, FOLDER_NAME) VALUES (2, 'Folder 2');
INSERT INTO MESSAGE(MESSAGE_ID, FOLDER_ID, SENDER) VALUES (11, 1, 'Sender 1');
INSERT INTO MESSAGE(MESSAGE_ID, FOLDER_ID, SENDER) VALUES (22, 2, 'Sender 2');
UPDATE MESSAGE SET FOLDER_ID=1 WHERE SENDER='Sender 2';
UPDATE MESSAGE SET FOLDER_ID=3 WHERE SENDER='Sender 2';
ORA-02291: Integritäts-Constraint (HR.ME_FO_FK) verletzt - übergeordneter Schlüssel nicht gefunden
DELETE FOLDER WHERE FOLDER_ID=1;
ORA-02292: Integritäts-Constraint (HR.ME_FO_FK) verletzt - untergeordneter Datensatz gefundenSo did you try to call your update manually in SQL*PLUS. I should show you the violated constraint with that you can check where the error lies.
