SQL行が正しい値を出力しない

Question

SQL文が新しく、データベースから販売された単位を印刷しようとしています。売却された単位の列の下には、「売却された単位」だけが印刷される番号は印刷されません。どんな助けでも大歓迎です。 ここに私のコードです：

SELECT brand_name, brand_type, Round(avgprice,2) AS "Average Price", "Units Sold" 
FROM lgbrand b 
JOIN (
    SELECT brand_id, Avg(prod_price) AS avgprice 
    FROM lgproduct 
    GROUP BY brand_id 
) sub1 ON b.brand_id = sub1.brand_id 
JOIN (
    SELECT brand_id, Sum(line_qty) AS "Units Sold" 
    FROM lgproduct p 
    JOIN lgline l ON p.prod_sku = l.prod_sku 
    GROUP BY brand_id 
) sub2 ON b.brand_id = sub2.brand_id 

ORDER BY brand_name;

試してみてくださいこの：

SELECT brand_name, brand_type, Round(avgprice,2) AS "Average Price", Units_Sold 
FROM lgbrand b 
JOIN (
    SELECT brand_id, Avg(prod_price) AS avgprice 
    FROM lgproduct 
    GROUP BY brand_id 
) sub1 ON b.brand_id = sub1.brand_id 
JOIN (
    SELECT brand_id, Sum(line_qty) AS Units_Sold 
    FROM lgproduct p 
    JOIN lgline l ON p.prod_sku = l.prod_sku 
    GROUP BY brand_id 
) sub2 ON b.brand_id = sub2.brand_id 

ORDER BY brand_name;
