but we can also ngeset directly in the database if it relates to the second table / reference,

if the mysql enggine use tools that replace the default MyISAM InnoDB.

If staying for Oracle classmates referencenya key, and set the ON DELETE CASCADE,

foreign key if it didelete,

his code examples,

CREATE TABLE supplier(Supplier_id numeric (10) not null,

supplier_name VARCHAR2 (50) not null,

CONTACT_NAME VARCHAR2 (50),Supplier_pk PRIMARY KEY constraint (supplier_id)

);

CREATE TABLE products

(Product_id numeric (10) not null,

supplier_id numeric (10) not null,

Constraint fk_supplierFOREIGN KEY (supplier_id)

REFERENCES supplier (supplier_id)ON DELETE CASCADE

);
