我有mysql的一个查询在那里我取多少已经销售总额不见了，

，但它显示previous dates [Date] => 2014-01-22[TotalSales] => 7，

它显示了这种方式，我怎样才能使它，因此，它显示当天的日期，并显示销售到现在

SELECT DATE(order_time) AS Date, SUM(Quantity) AS TotalSales 
FROM ss_orders,ss_ordered_carts 
GROUP BY date; 

Answer 1

然后添加一个WHERE子句，你order_time今天的日期比较。 是这样的：

SELECT DATE(order_time) AS Date, SUM(Quantity) AS TotalSales 
     FROM ss_orders,ss_ordered_carts 
     WHERE DATE(order_time) = DATE(NOW()) 
     group by date;
