Sales: Id, itemId, timestamp

您正在寻找此查询吗？

SELECT s.ItemId, CONVERT (DATE, timestamp), sum(price)
FROM Sales s
INNER JOIN Items i on s.ItemId = i.ItemId
GROUP BY s.ItemId, CONVERT (DATE, timestamp)
ORDER BY CONVERT (DATE, timestamp), ItemId;

Answer 2

SELECT convert(date,timestamp) AS timestamp,
       itemId, 
       count (itemId)*price
FROM sales AS S left JOIN Items AS i 
ON s.itemId=i.itemId
GROUP BY  timestamp,
          itemId
ORDER BY   itemId
