I did this
INSERT INTO product (prod_id, prod_price, prod_avail, prod_mdate, prod_edate, cust_id, sto_id, sup_id)
Values('RBL01001',4.50,'Available',TO_DATE('29-MAR-21','DD-MON-YY'),TO_DATE('29-APR-21','DD-MON-YY'),0001,'Kapar1','SUPP-001');
and this is the result
ORA-02291: integrity constraint (PROD_SUP_FK) violated - parent key not found
ORA-02291: integrity constraint (PROD_SUP_FK) violated - parent key not found
ORA-06512: at "SYS.DBMS_SQL", line 1721

Alter table product

ALTER TABLE product ADD CONSTRAINT prod_sto_fk FOREIGN KEY (sto_id)

CodePudding user response:
First you have to insert rows into "master" tables (customer
, supplier
, bakery
/store
), then into their "child" table (product
).
By the way, what is this bakery / store
thing supposed to do? Such a syntax is invalid:
ALTER TABLE product ADD CONSTRAINT prod_sto_fk FOREIGN KEY (sto_id)
REFERENCES bakery / store (sto_id) ENABLE;
