WHERE条件に一致しないレコードを含める

Question

これは素晴らしい動作します。しかし、私はまた、その日付範囲で販売されていないアイテムを含めることを望みます。現在、選択した期間内に販売されたアイテムのみを表示しています。私もそれを販売していない項目を表示したいと思います。コメントに基づいて

SELECT i.item_number, i.item_name, ish.avg_cost, ish.avg_retail, ish.avg_daily_sales, 
CASE WHEN i.sold_by_id = '0' THEN 'pcs' 
    WHEN i.sold_by_id = '1' THEN 'lbs' 
    WHEN i.sold_by_id = '2' THEN 'lbs' 
END [Sold_by] 
FROM inventory i 
INNER JOIN 
    (SELECT ish.item_number, AVG(avg_cost) as avg_cost, AVG(avg_retail) as avg_retail, ROUND(AVG(total_sold),0) as avg_daily_sales 
    FROM inventory_sales_history ish 
     LEFT JOIN Inventory i ON i.item_number = ish.Item_Number 
WHERE ish.the_date BETWEEN '12-11-2016' AND '12-18-2016' 
AND ish.item_number IN (SELECT item_number FROM inventory i JOIN department d ON d.department_id = i.department_id WHERE d.category_id = '4') 
GROUP BY ish.item_number)ish 
ON i.item_number = ish.item_number 
ORDER BY i.item_name

inventoryテーブルにだが、ないinventory_sales_historyテーブル

Answer 1

SELECT i.item_number, i.item_name, ish.avg_cost, ish.avg_retail, ish.avg_daily_sales, 
CASE WHEN i.sold_by_id = '0' THEN 'pcs' 
    WHEN i.sold_by_id = '1' THEN 'lbs' 
    WHEN i.sold_by_id = '2' THEN 'lbs' 
END [Sold_by] 
FROM inventory i 
LEFT JOIN 
    (SELECT ish.item_number, AVG(avg_cost) as avg_cost, AVG(avg_retail) as avg_retail, ROUND(AVG(total_sold),0) as avg_daily_sales 
    FROM inventory_sales_history ish 
     LEFT JOIN Inventory i ON i.item_number = ish.Item_Number 
WHERE ish.the_date BETWEEN '12-11-2016' AND '12-18-2016' 
AND ish.item_number IN (SELECT item_number FROM inventory i JOIN department d ON d.department_id = i.department_id WHERE d.category_id = '4') 
GROUP BY ish.item_number)ish 
ON i.item_number = ish.item_number 
ORDER BY i.item_name

にこれが同じであるとして特定されて販売しているアイテムDVTの答えとして、サブクラスへの結合を内部結合から左結合に変更するという点では、私はちょうどそれを見て少し質問をリファクタリングしました。
