In samples we can look Computer exdends Product. But, if you try get field of products by accessing to child Computer object nothing getting…
Extends affect only to identity and nothing else…
Is it extend? It's not extend - it's one to one relation.
Extends by my mind is:
Product {
Id,
Name,
Price
}
Computer extend Product {
Cpu
}
And this mean that Select c.name FROM Computer WHERE id = $1 are work propertly and
computer.setName("Artlantis");
computer.setPrice("$ 1200");
computer.setCPU("Pentium 4");
db.create(computer);
are work too.
