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). CREATE TABLE supplier ( supplier_id numeric(10) not null, supplier_name varchar2(50)

Anyone have any ideas? http://stackoverflow.com/questions/13518246/violated-parent-key-not-found-error 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 the field is_group on the table GroupMembers must have an identical value on the table Members and group_name field. In my opinion this is bad practice. First of all you should have a primary key field on the table GroupMembers. You should not store the names of the group members in the table GroupMembers, but their corresponding id from the table Members. Also the table Members, should look something like this: CREATE TABLE Members ( member_id NUMBER PRIMARY KEY member_name VARCHAR2(40), CONSTRAINT g_id_pk PRIMARY KEY(member_id), CONSTRAINT m_group_name_fk FOREIGN KEY(group_name) REFERENCES Artist(artistic_name)); Then

Beyond having the ability to cleanly join tables and merge parameters, a number of devices in the software permit the access to and referencing of data from multiple tables, with unique features that allow you to create statements that can render formerly complex database issues with relatively little trouble. Still, no user is perfect and no database can predict all of the potential errors that can arise during everyday use. In the realm of manipulating data across multiple data tables, a common error that you can encounter is the ORA-02291. The Problem ORA-02291 is typically accompanied with the message, “integrity constraint violated – parent key not found”. This means that you attempted to execute a reference to a certain table using a primary key. However, in the process of doing so, the columns that you specified failed to match the primary key. The error can also be triggered when referencing a primary
