sqlserver 中Cube，rollup的使用

 

(1)

select name,subject,result from resultInfo

(2)

select name,sum(result) from resultInfo group by name

（3）

select name ,sum(result) as 總分 from resultInfo group by name with cube

select case when grouping(name)=1 then '總計' else name end as 姓名 ,sum(result) as 總分 from resultInfo group by name with cube

 grouping函數：若是列中的值來來自查詢數據,則grouping返回0,若是列中的值是cube產生的空值,則返回1

（4）

select name ,sum(result) as 總分 from resultInfo group by name with rollup

select case when grouping(name)=1 then '總計' else name end as 姓名 ,sum(result) as 總分 from resultInfo group by name with rollup

（5）

select name,subject,sum(result) as 總分 from resultInfo group by name,subject with cube

按第1、二個字段的和計和最後的總計

（6）

select name,subject,sum(result) as 總分 from resultInfo group by name,subject with rollup

按第一個字段的總計和最後的合計
