G、统计模块

1、能够统计某个时间段之内（开始时间及结束时间）各个商品类别的销售金额；（存储过程）

DROP PROCEDURE IF EXISTS p_salessum;
CREATE PROCEDURE p_salessum(starttime timestamp,endtime timestamp)
BEGINSELECT x.category_id,category_name,总金额 FROM(SELECT category_id,sum(sales_sum) 总金额 FROM tb_sales a JOIN tb_goods b ON a.goods_id=b.goods_id WHERE sales_dateBETWEEN starttime AND endtime GROUP BY b.category_id) x JOIN tb_category y ON x.category_id=y.category_id;
END;// 调用
call p_salessum('2016-09-09','2016-09-30');

调用结果：

2、能够统计某个时间段之内（开始时间及结束时间）各个商品类别的进货金额；（存储过程）

DROP PROCEDURE IF EXISTS p_purchasesum;
CREATE PROCEDURE p_purchasesum(starttime timestamp,endtime timestamp)
