编写查询时如何计算值 [英] how to calculate value while writing query

问题描述

使用以下查询，我得到以下数据
从条目WHERE中选择项目，收入，日期，数量，金额("2012-03-24"和"2012-03-25"之间的日期)
项目数量收入金额日期
item1 10 10 100 2012-03-24
item2 10 10 100 2012-03-24
item3 10 10 100 2012-03-24
item4 10 10 100 2012-03-25
item1 10 10 100 2012-03-25
item2 10 10 100 2012-03-25
item3 10 10 100 2012-03-25
item4 10 10 100 2012-03-25

有人可以建议我通过这种方式获取数据的SQL查询是什么吗?
项目数量收入金额
