Join2表和按日期分组

Question

我想对所有win_ticket求和并将其除以2表中所有sold_ticket的总和，以获得百分比，然后按日期将其分组。

这根本不起作用.....

sold_ticket

customer_winner

$query = "SELECT 
      sold_ticket.date, sold_ticket.sold_ticket, 
              SUM(sold_ticket) AS sold_ticket, 
      customer_winner.date, customer_winner.win_ticket, 
              SUM(win_ticket) AS lottery_win

      FROM sold_ticket

      INNER JOIN customer_winner

      ON sold_ticket.date = customer_winner.date

      GROUP BY date 
      ";

Answer 1

需要将sold_ticket.date或customer_winner.date或两者分组。
