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 FOREIGN KEY (supplier_id) REFERENCES supplier (supplier_id) ); Then you try inserting into the products table as follows: INSERT INTO products (product_id, supplier_id) VALUES (1001, 5000); You would receive the following error message: Since the supplier_id value of 5000 does not yet exist in the supplier table

Still I am getting this error. 1) Parent table's primary key is Child table's primary key as well as foreign key. 2) Parent table's primary key is referred as primary key in some other child table as well. 3) But not using Supertype-Subtype relationship.

Still I am getting this error.You might be using the same sequence object but while inserting you are using sequence.nextval for your Foreign Key. Can you prove whats happening using a sample Parent, Child Table and some dummy data. 1)

Posteriormente le añadiremos la clave primaria.CREATE TABLE PRUEBA ( ID NUMBER NOT NULL, DESCRIPCION VARCHAR2(10)); INSERT INTO PRUEBA(1,'HOLA'); ALTER TABLE PRUEBA ADD CONSTRAINT PRUEBA_PK PRIMARY KEY(ID);Ahora creamos la segunda tabla, que tendra una foreign key a la tabla anterior. CREATE TABLE PRUEBA2(COL1 NUMBER); ALTER TABLE PRUEBA2 ADD (CONSTRAINT PRUEBA2_FK FOREIGN KEY (COL1) REFERENCES PRUEBA(ID));Ahora insertaremos en esta tabla (PRUEBA2) un valor que no este y Oracle nos devolverá un error tipo:ORA-02291: integrity constraint (MANTE90.PRUEBA2_FK) violated - parent key not found Ahora recuperaremos del error (SQLERRM) el número del error que devuelve y lo buscaremos en la tabla de constrains en las columnas.SET SERVEROUTPUT ON DECLARE COLUM_ERR USER_CONS_COLUMNS.COLUMN_NAME%TYPE; L_CONS USER_CONSTRAINTS.CONSTRAINT_NAME%TYPE; L_START NUMBER; L_STOP NUMBER; E_CONSVIOLATION EXCEPTION; PRAGMA EXCEPTION_INIT(E_CONSVIOLATION, -02291); BEGIN INSERT INTO PRUEBA2 VALUES(3); EXCEPTION WHEN E_CONSVIOLATION THEN L_START := INSTR( SQLERRM, '(' ) + 1; L_STOP := INSTR( SQLERRM, ')' ); L_CONS := SUBSTR(SQLERRM, L_START, L_STOP-L_START); L_START := INSTR( L_CONS, '.' ) + 1; L_CONS := SUBSTR(L_CONS, L_START, L_STOP-L_START); SELECT COLUMN_NAME INTO COLUM_ERR FROM USER_CONS_COLUMNS WHERE TABLE_NAME = 'PRUEBA2' AND CONSTRAINT_NAME = L_CONS; D
