Parent Key And Foreign Key

ORA-02291: integrity constraint (string.string) violated - parent key not found Cause: A foreign key value has no matching primary key value. Action: Delete the foreign key or add a matching primary key. For an insert statement, this ORA-02291 error is common when you are trying to insert a child how to find parent table in oracle without a matching parent, as defined by a foreign key constraint. In that case, you need to add the parent row to the table and then re-insert your child table row.See the dba_constraints view to find the parent table.To fully understand [primary and foreign key constraints, see the book Easy Oracle Jumpstart, to explain these concepts: Burleson is the American Team Note: This Oracle documentation was created as a support and Oracle training reference for use by our DBA performance tuning consulting professionals.

Description When you encounter an 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) not null, contact_name varchar2(50), CONSTRAINT supplier_pk PRIMARY KEY (supplier_id) ); CREATE TABLE products ( product_id numeric(10) not null, supplier_id numeric(10) >not null, CONSTRAINT fk_supplier F

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 key that does not exist for the table in question.  Before moving on, we should note a few things about primary keys. A primary key is a field or combination of fields that can distinctly denote a record. It can be established in either an ALTER TABLE or CREATE TABLE statement. A given table can only have one primary key, and none of the fields that populate the primary key can hold a null value. A primary key cannot exceed thirty-two columns. Now that we have an understanding of primary keys, we can address the error at hand. Often, the error will arise when there is a parent-child relationship between two tables via a foreign
