显示和列SQL代码

Question

我需要使用SQL代码在col下显示sum col（item）吗？这是可能的

 Code            item                         
 ----            ----               
 1               30          
 3               40        
 4               50
 9               80
----             ----
Total            200

Answer 1

使用Rollup获取摘要行

SELECT CASE
         WHEN Grouping(code) = 1 THEN 'Total'
         ELSE Cast(code AS VARCHAR(50))
       END,
       Sum(item)
FROM   Yourtable
GROUP  BY code WITH rollup 

Answer 2

select * from (select * from #Table1
union
select null, sum(item) item from #Table1)a
order by item 

Answer 3

DECLARE @Table1  TABLE 
    (Code int, item int)
;

INSERT INTO @Table1
    (Code, item)
VALUES
    (1, 30),
    (3, 40),
    (4, 50),
    (9, 80)
;

脚本：

select Code , sum(item)item
 from @Table1
 group by GROUPING SETS((Code) , ())
 order by Code DESC

Answer 4

Select
   Code,
   item 
from
   @ table_name 
Union All
select
   Null,
   sum(item)item 
from
   @ table_name

由于我们使用的联合如此明显，并且将保存按操作的顺序。
