SQL分组查询做相关统计

根据项目名称分组得到相关数据统计

 

select row_number() over(order by lxmc) as 编号, lxmc 项目名称,sum(ssj) as 单价,sum(sdj) as 订单价,sum(hzs) as 成本价,sum(hjs) as 折扣价,isnull(sum(ssf),0) as 批发价, count(lxmc) as 数量  from Y_gcdak where lxmc!='' and  lxmc is not null   group by lxmc

 

group by lxmc 根据项目名称分组

 

row_number() over(order by lxmc)  根据项目名称分组后得到的相关序号

 

isnull(sum(ssf),0) isnull()函数的作用:得到的值如果是null则替换成0
