有这样的数据结构Id int
SerialNumber nvarchar
SubCategories nvarchar和类似下面这样的数据Id SerialNumber SubCategories
1 NO.2009.10 9,11
2 NO.2009.12 20
3 NO.2009.11 空字符串
4 NO.2009.14 7,8,9我希望得到以下数据:
Id SerialNumber SubCategories
1 NO.2009.10 9
1 NO.2009.10 11
2 NO.2009.12 20
3 NO.2009.11 空字符串
4 NO.2009.14 7
4 NO.2009.14 8
4 NO.2009.14 9希望得到高手解答.谢谢.

拆分表:
if not object_id('Tab') is null
drop table Tab
Go
Create table Tab([Col1] int,[COl2] nvarchar(5))
Insert Tab
select 1,N'a,b,c' union all
select 2,N'd,e' union all
select 3,N'f'
Go--SQL2000用辅助表:
if object_id('Tempdb..#Num') is not null
drop table #Num
go
select top 100 ID=Identity(int,1,1) into #Num from syscolumns a,syscolumns b
Select
a.Col1,COl2=substring(a.Col2,b.ID,charindex(',',a.Col2+',',b.ID)-b.ID)
from
Tab a,#Num b
where
charindex(',',','+a.Col2,b.ID)=b.ID --也可用 substring(','+a.COl2,b.ID,1)=','
--2000不使用辅助表
Select
a.Col1,COl2=substring(a.Col2,b.number,charindex(',',a.Col2+',',b.number)-b.number)
from
Tab a join master..spt_values b
ON B.type='p' AND B.number BETWEEN 1 AND LEN(A.col2)
where
substring(','+a.COl2,b.number,1)=','
SQL2005用Xml:select
a.COl1,b.Col2
from
(select Col1,COl2=convert(xml,'<root><v>'+replace(COl2,',','</v><v>')+'</v></root>') from Tab)a
outer apply
(select Col2=C.v.value('.','nvarchar(100)') from a.COl2.nodes('/root/v')C(v))b
SQL05用CTE:--此法roy博客;with roy as
(select Col1,COl2=cast(left(Col2,charindex(',',Col2+',')-1) as nvarchar(100)),Split=cast(stuff(COl2+',',1,charindex(',',Col2+','),'') as nvarchar(100)) from Tab
union all
select Col1,COl2=cast(left(Split,charindex(',',Split)-1) as nvarchar(100)),Split= cast(stuff(Split,1,charindex(',',Split),'') as nvarchar(100)) from Roy where split>''
)
select COl1,COl2 from roy order by COl1 option (MAXRECURSION 0)生成结果:
/*
Col1 COl2
----------- -----
1 a
1 b
1 c
2 d
2 e
3 f
*/
我选择了 SQL05用CTE 这种方法.请问我在这个后面select COl1,COl2 from roy order by COl1 option (MAXRECURSION 0)
加上
inner join
请问这样可以吗?为什么报关键字 'inner' 附近有语法错误。
像下面这样
with BrandSplit as
(select Id,SerialNumber,BarndName,MenuId,CategoryId,SubCategoryId=cast(left(SubCategories,charindex(',',SubCategories+',')-1) as nvarchar(100)),Split=cast(stuff(SubCategories+',',1,charindex(',',SubCategories+','),'') as nvarchar(100)),UseRange,Hits,Img,Assignee,BuyRegion,OrderValue from Brand
union all
select Id,SerialNumber,BarndName,MenuId,CategoryId,SubCategoryId=cast(left(Split,charindex(',',Split)-1) as nvarchar(100)),Split= cast(stuff(Split,1,charindex(',',Split),'') as nvarchar(100)),UseRange,Hits,Img,Assignee,BuyRegion,OrderValue from BrandSplit where split>''
)
select Id,SerialNumber,BarndName,MenuId,CategoryId,SubCategoryId,UseRange,Hits,Img,c.CategoryName,Assignee,BuyRegion,OrderValue from BrandSplit option (MAXRECURSION 0)
inner join Category c on c.Id=CategoryId
谢谢.
create view v_b
as
with BrandSplit as
(select Id,SerialNumber,BarndName,MenuId,CategoryId,SubCategoryId=cast(left(SubCategories,charindex(',',SubCategories+',')-1) as nvarchar(100)),Split=cast(stuff(SubCategories+',',1,charindex(',',SubCategories+','),'') as nvarchar(100)),UseRange,Hits,Img,Assignee,BuyRegion,OrderValue from Brand

)
select Id,SerialNumber,BarndName,MenuId,CategoryId,SubCategoryId,UseRange,Hits,Img,c.CategoryName,Assignee,BuyRegion,OrderValue
from BrandSplit inner join Category c on c.Id=CategoryId option (MAXRECURSION 0)
这样?
Select
a.Col1,COl2=substring(a.Col2,b.number,charindex(',',a.Col2+',',b.number)-b.number)
from
Tab a join master..spt_values b
ON B.type='p' AND B.number BETWEEN 1 AND LEN(A.col2)
where
substring(','+a.COl2,b.number,1)=','
