如何按日期制作重演数据组

Question

有人知道如何按日期分组制作重演数据吗？我想收集1天/周/月的所有交易。我想加入表Transaction和Detail Transaction，其中包含将在重演中显示的列。我坚持这个问题。任何回复都将不胜感激。

SELECT a.TransactionID,
       a.Buyer_Code,
       a.Date_Transaction,
       b.NuggetID,
       b.Qty,
       b.Sub_Total,
       a.Total_Price

       DetailTransaction b
GROUP  BY a.Date_Transaction

       QTY = SUM(b.Qty),
