1 1.1.1.1 1.1.2 1.3 2 2.1 ...这样的数据sql排序

----其中wbscode 为1  1.1.1  1.1.2 这样的编码。

主要关注的地方为：1 分解函数   2.根据分解函数进行行转列   3 最终合并数据去重

-----分解函数
CREATE FUNCTION dbo.Split( @String varchar(8000), @Delimiter char(1))
returns @temptable TABLE (items varchar(8000),splitLevel int )
as
begin
declare @idx int
declare @slice varchar(8000)
declare @index int
set @index=0
select @idx=1
if len(@String)<1 or @String is null return

while @idx!=0
begin
set @idx=charindex(@Delimiter,@String)
if @idx!=0
set @slice=left(@String,@idx-1)
else
set @slice=@String

if(len(@slice)>0)
set @index=@index+1;
insert into @temptable(Items,splitLevel) values(@slice,@index)

set @String=right(@String,len(@String) -@idx)
if len(@String) =0 break
end
return
end
go

---更新执行版本的任务序号数据
update PMM_TaskPerformance set Sequence=c.se from PMM_TaskPerformance tp
inner join

---进行排序获取排序数据
select ROW_NUMBER() over(order by level1,level2,level3,level4,level5,level6,level7,level8,level9,level10 ) as se, *
from (
-----数据进行行转列
select performancetaskid,WBSCode,sum(level1)as level1,SUM(level2) as level2,sum(level3) as level3,sum(level4) as level4
,sum(level5) as level5,sum(level6) as level6,sum(level7) as level7,sum(level8) as level8,sum(level9) as level9,sum(level10) as level10

---执行查询与编码分解
select items 'SalesOffice',splitLevel,
case splitLevel when 1 then items else 0 end as level1,
case splitLevel when 2 then items else 0 end as level2,
case splitLevel when 3 then items else 0 end as level3,
case splitLevel when 4 then items else 0 end as level4,
case splitLevel when 5 then items else 0 end as level5,
case splitLevel when 6 then items else 0 end as level6,
case splitLevel when 7 then items else 0 end as level7,
case splitLevel when 8 then items else 0 end as level8,
case splitLevel when 9 then items else 0 end as level9,
case splitLevel when 10 then items else 0 end as level10,
--执行版本任务id
pt.id as performancetaskid ,pt.WBSCode,pt.Level from PMM_TaskPerformance pt
CROSS apply dbo.split(pt.WBSCode,'.')

----以下三行为筛选条件，可以不用关注
--join PMM_WBSTask t on t.ID=pt.WBSTask
---项目主键条件
----where t.ProjectMaster='1002209270220008'
)a group by performancetaskid,WBSCode
)b
)c
on c.performancetaskid=tp.ID

---删除临时方法
drop FUNCTION dbo.Split;
