Аве Кодер! В этом уроке мы на практике разберем пользу от первичных ключей. В качестве примера мы возьмем бонусную схему вымышленного работодателя по которому, наши работники должны получить в качестве бонуса велосипед. Но не все так очевидно - наше решение в Postgresql должно отвечать трем обязательным условиям: 1) Работник может получить только один велосипед 2) Велосипед может принадлежать только одному работнику 3) Это может быть либо велосипед, либо ничего. В этом нам как раз и помогут внешние ключи.

We will start with Simple primary key. You can create Primary key either with Create Table statement of by using Alter table Statement. Let's define simple primary key using create table statements. With create table statement we can either define primary key at column level or at table level. We will start with defining Primary key at column level using create table statement. You just have to put keyword Primary key after data type and size of column while defining a column of a table. Here oracle server will create a primary key on product id with default constraint name which will be slightly difficult to understand. You can give your own name to your constraint which is also a good practice.
