Tavsif

SQL buyraklaridan GROUP BY va HAVING lar orqali ma'lumotlarni guruhlash imkonini beradi. GROUP BY buyragi ustida ma'lumotlar bir qator holatida qaytariladi va unga asoslangan ustida amalni bajaradi. HAVING esa GROUP BY dan keyin keladigan shart buyrakidir va guruhlangan ma'lumotlarga shartni qo‘yadi.
