关于C#做月统计思路方法
最近想做一个月报表统计项目的应用程序,根据ACCESS数据库表里的数据统计一个月每天3个时段酒精、桔水这两种物资重量和罐数（一条记录表示一罐）。统计每天酒精和桔水分别称量的合计重量，最后月的合计统计。数据库表记录：
要实现报表打印的格式
哪位大侠指点一下要怎样实现统计的方法，大概思路? 报表 月统计 --------------------编程问答-------------------- 一般报表的分组功能就能实现 --------------------编程问答-------------------- 自己写SQL搞定吧 --------------------编程问答-------------------- sql or linq --------------------编程问答-------------------- sql 聚合函数就能搞定。 --------------------编程问答-------------------- 除 --------------------编程问答-------------------- 看结果：

这就完成一半工作了 --------------------编程问答-------------------- 这样子写法，应该。。。。。
