两个产品的月销售额，mysql查询

Question

我已经使用两个查询更新了以下代码，它们运行正常。

$query1="SELECT sum(sub_total) as limonadeTotal  from ucommerce_order_line WHERE part_number = '$part_number' group by MONTH(date_created)";

$query2="SELECT sum(sub_total) as strawberryLimonadeTotal from ucommerce_order_line WHERE part_number = '$part_number' group by MONTH(date_created)";

感谢您的帮助

试试这个..

使用月份功能对日期的月份进行分组，并且＆＃34;总和＆＃34;创建小计总数

select sum(sub_total) as total from ucommerce_order_line group by MONTH(date_created)
