Parent Key And Foreign Key
Join them; it only takes a minute: Sign up violated - parent key not found error up vote 0 down vote favorite I have the following error appearing: INSERT INTO GroupMembers VALUES ('Goldfrat', 'Simon Palm') * ERROR at line 1: ORA-02291: integrity constraint (SHAHA1.IAM_IS_GROUP_FK) violated - parent key not found The constraint in the GroupMembers table is: CONSTRAINT how to find parent table in oracle iam_is_group_fk FOREIGN KEY(is_group) REFERENCES Members(group_name) The Members Table looks like this: CREATE TABLE Members ( group_name VARCHAR2(40), CONSTRAINT g_id_pk PRIMARY KEY(group_name), CONSTRAINT m_group_name_fk FOREIGN KEY(group_name) REFERENCES Artist(artistic_name)); All of the tables are created fine until it comes to creating the GroupMembers table. Anyone have any ideas? I've been scratching for quite a while. sql database oracle share|improve this question edited Oct 28 '13 at 11:06 Kiquenet 5,0822487148 asked Nov 22 '12 at 18:23 AkshaiShah 75641834 I'm scratching for the error,too. I've disabled the foreign constraint and did some insert and delete actions. After I updated, I could not enable this foreign constraint. It said ORA-02298: cannot validate (PRODUSR.SYS_C0037867) - parent keys not found. But I checked many times and still cannot find out any records not in parent table. –user3572072 Apr 25 '14 at 8:11 add a comment| 3 Answers 3 active oldest votes up vote 2 down vote accepted The problem is that CONSTRAINT iam_is_group_fk FOREIGN KEY(is_group) REFERENCES Members(group_name); references the table Members on the group_name field. This means that

Join them; it only takes a minute: Sign up “Parent Key Not Found” although it exists (within the TX) up vote 2 http://stackoverflow.com/questions/13518246/violated-parent-key-not-found-error down vote favorite I just observed a strange behaviour (of course Oracle is probably supposed to behave this way, but it didn't fit in my world view yet): I try to insert two rows into a parent and a child table, both within the same transaction: INSERT INTO V_Parent (ID, Name) VALUES (777, 'Hello World'); INSERT INTO T_Child (ParentID, Name) VALUES (777, 'Foo Bar'); The Child table has a http://stackoverflow.com/questions/3500454/parent-key-not-found-although-it-exists-within-the-tx (ParentID) references Parent.ID foreign key constraint. On the second statement Oracle fails with the error message "Parent key not found." If I disable the FK constraint, it works. I have asserted that the ParentID and the Parent.ID match, and I am 100% sure that the first line is executed successfully before the second one. Further, I have tried to commit each statement, which worked fine. However, as the prefixes in my code example suggest, the first INSERT is actually done on a view of the parent table. The reason is that I use NHibernate and the mapping uses the view in background (which didn't cause any problems until today). Q1: Could it be that inserting on a view is deferred by Oracle so that the second statement fails? Q2: How can I remedy this problem best? Do I need to define INSTEAD OF triggers on the views? Can I change a setting on the VIEW definition? Can I change a setting on the FOREIGN KEY definition? (I must not bend the hibernate mapping to the original table: It's a demand to use the views so changes and/or security issues can be hidden behind the views) Details: C# WinForms Application - NHibernate - Oracle 10.2 - T_Child: S
