CREATE TABLE ats_test

  (

     empcode      NVARCHAR(40),

     Day_01       NVARCHAR(10),

     Day_02       NVARCHAR(10),

     Day_03       NVARCHAR(10),

     Day_04       NVARCHAR(10),

     Day_06       NVARCHAR(10),

     Day_07       NVARCHAR(10),

     Day_08       NVARCHAR(10),

     Day_09       NVARCHAR(10),

     Day_10       NVARCHAR(10)

  ) 



insert into ats_test values ('EAA45463','N4/D2/S2','N4/D2/S2','L7.5','N7.5','N7.5','N7.5','N7.5','N7.5','N7.5','N7.5')

insert into ats_test values ('EAA81137','X','L8','L8','N7.5','N7.5','N7.5','X','X','X','N6.5')

求高手们指导下，如何统计Day_01~Day_10列中第一个字母相同的数据的数字部分和？
其中比较特殊的是一个字段数据可以是'N4/D2/S2'
我想做个视图，对每个人做统计，统计信息的列名就为empcode、N、D、S、X、L

这个主要是通过先建个函数，然后再进行分拆，可以指定按照哪个字符进行分拆，最后计算：

--建一个字符串拆分函数
if exists(select * from sys.objects where name = 'f_splitSTR' and type = 'tf')
   drop function dbo.f_splitSTR
go

create function dbo.f_splitSTR
(
	@s varchar(8000),     --要分拆的字符串
	@split varchar(10)    --分隔字符
) 
returns @re table(                      --要返回的临时表
                     col varchar(1000)  --临时表中的列 
                 )
as
begin   
  declare @len int
  
  set @len = LEN(@split)      --分隔符不一定就是一个字符，可能是2个字符
  
  while CHARINDEX(@split,@s) >0
  begin
	insert into @re 
	values(left(@s,charindex(@split,@s) - 1))
	
	set @s = STUFF(@s,1,charindex(@split,@s) - 1 + @len ,'')    --覆盖：字符串以及分隔符
  end
  
  insert into @re values(@s)
  
  return   --返回临时表
end
go  


If object_id('ats_test') is not null
   drop table ats_test
go

--建表
