Symptoms
Two tables are mapped with a one-to-many relationship (Master-Detail), using a MultiTableInfo descriptor.
With the given foreign key mappings, insertion into the tables using Toplink 10.1.3.3 fails with the following message:
Internal Exception: java.sql.SQLException: ORA-02291: integrity constraint (SCOTT.FK_SECONDARY) violated - parent key not found
However, when doing the same insertion with Toplink 9.0.4 API it works fine.
Example
Here is an example structure of two such tables :
CREATE TABLE PRINCIPAL (
ID_PRC NUMBER(22) NOT NULL,
PRC_NAME VARCHAR2(50) NOT NULL,
PRC_SECONDARY_ID NUMBER(22) NOT NULL
);
CREATE TABLE SECONDARY (
ID_SCN NUMBER(22) NOT NULL,
SCN_DESC VARCHAR2(100)
);
CREATE SEQUENCE SN_WAT INCREMENT BY 1 START WITH 1;
ALTER TABLE PRINCIPAL ADD CONSTRAINT PK_PRINCIPAL PRIMARY KEY (ID_PRC) USING INDEX;
ALTER TABLE SECONDARY ADD CONSTRAINT PK_SECONDARY PRIMARY KEY (ID_SCN) USING INDEX;
ALTER TABLE PRINCIPAL ADD CONSTRAINT FK_SECONDARY FOREIGN KEY (PRC_SECONDARY_ID) REFERENCES SECONDARY (ID_SCN);
ID_PRC NUMBER(22) NOT NULL,
PRC_NAME VARCHAR2(50) NOT NULL,
PRC_SECONDARY_ID NUMBER(22) NOT NULL
);
CREATE TABLE SECONDARY (
ID_SCN NUMBER(22) NOT NULL,
SCN_DESC VARCHAR2(100)
);
CREATE SEQUENCE SN_WAT INCREMENT BY 1 START WITH 1;
ALTER TABLE PRINCIPAL ADD CONSTRAINT PK_PRINCIPAL PRIMARY KEY (ID_PRC) USING INDEX;
ALTER TABLE SECONDARY ADD CONSTRAINT PK_SECONDARY PRIMARY KEY (ID_SCN) USING INDEX;
ALTER TABLE PRINCIPAL ADD CONSTRAINT FK_SECONDARY FOREIGN KEY (PRC_SECONDARY_ID) REFERENCES SECONDARY (ID_SCN);
