9 ORA-02291: integrity constraint violated - parent key not found TweetSumoMe Tweet ORA-02291: integrity constraint violated - parent key not found error occurs when we try to insert a row in a child table with a foreign key constraint and the related foreign key data is missing from parent table. Let us create a scenario which causes ORA-02291 error. Let us create an EMPLOYEE table which holds the employee information like name ,id and salary. Here emp_id is the primary key column. SQL> create table EMPLOYEE( name VARCHAR2(50), emp_id NUMBER, salary NUMBER(8,2), CONSTRAINT EMPLOYEE_ID_PK PRIMARY KEY (emp_id)); Table created Now create an Employee address table which holds the address details of the employees.The address table is linked to EMPLOYEE table through the foreign key emp_id; SQL> create table EMPLOYEE_ADDRESS( address varchar2(200), emp_id number, CONSTRAINT EMP_ADD_FK FOREIGN KEY (emp_id)REFERENCES EMPLOYEE(emp_id)); Table created Now let us insert one record in EMPLOYEE table. SQL> insert into EMPLOYEE values(' ABCD',1,12345); 1 row inserted Now let us add address for this particular employee in EMPLOYEE_ADDRESS table. SQL> insert into EMPLOYEE_ADDRESS values('abcd efgh',1); 1 row inserted Now while entering the data in EMPLOYEE_ADDRESS table the data should be already present in EMPLOYEE table.Otherwise foreign key violation will result. SQL> insert into EMPLOYEE_ADDRESS values('abcd efgh',8); ORA-02291: integrity constraint violated - parent key not found Related Articles,Oracle/PLSQL: Foreign Keys | Oracle Referential Integrity Oracle/PLSQL: Composite Primary Key Oracle/PLSQL: Primary Key and Composite Primary Key ALTER TABLE to ADD PRIMARY KEY in Oracle.
