Количество заказов в статусе "processing" по каждому исполнителю за март 2024 года для приоритетных заказов:

SELECT executor, COUNT(*) AS processing_orders_count
FROM orders
WHERE status = 'processing'
  AND priority = 'high'
  AND order_date >= '2024-03-01' AND order_date < '2024-04-01'
GROUP BY executor;

Средняя выручка по каждой категории товаров:

SELECT category, AVG(revenue) AS avg_revenue
FROM orders
GROUP BY category;

Количество уникальных клиентов, сделавших заказы в категории "Electronics":

SELECT COUNT(DISTINCT client_id) AS unique_clients
FROM orders
WHERE category = 'Electronics';

Список заказов, которые были отклонены или отменены:

SELECT *
FROM orders
WHERE state IN ('rejected', 'cancelled');

Исполнитель, который обработал наибольшее количество заказов в статусе "completed":

SELECT executor
FROM orders
WHERE status = 'completed'
GROUP BY executor
ORDER BY COUNT(*) DESC
LIMIT 1;
