读取数据库后分号的数据怎么分开

我在oracle中读取了一组数据（x，y），这个x和y是随时变化的，那么中两个数据分别赋值给两个变量a，b怎么处理编写语言为vb.net谢谢

split函数
dim s as string = "1,2"
dim arr() as string = s.Split(",")
msgbox arr(0)
msgbox arr(1)

拆分表:

--> --> (Roy)生成測試數據

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)=','

SQL2005用Xml:

select

a.COl1,b.Col2
from

(select Col1,COl2=convert(xml,' '+replace(COl2,',',' ')+' ') from Tab)a
outer apply
(select Col2=C.v.value('.','nvarchar(100)') from a.COl2.nodes('/root/v')C(v))b

SQL05用CTE:

;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

      a 
      b 
      c 
      d 
      e 
      f
