如果我们能看到你的拆分字符串函数，可能会更容易回答这个问题。我的答案是使用我的split函数的一个版本。
我会在你的拆分函数中包含一个行号，你可以用它来连接拆分的字符串和拆分的值。
分割功能：

CREATE FUNCTION [dbo].[Split](@String varchar(MAX), @Delimiter char(1))       
returns @temptable TABLE (items varchar(MAX), rn int)       
as       
begin      
    declare @idx int       
    declare @slice varchar(8000)   
    declare @rn int = 1 -- row number that increments with each value in the delimited string

    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)  
            insert into @temptable(Items, rn) values(@slice, @rn)       

        set @String = right(@String,len(@String) - @idx)       
        set @rn = @rn +1

        if len(@String) = 0 break       
    end   
return 
end;

然后，如果有多个要拆分的列，则可以使用类似于以下的查询：

INSERT INTO dbo.tblSplitData(SplitKey, SplitString, SplitValues)
select s.rawkey,
  s.splitstring,
  v.splitvalues
from
(
  SELECT d.RawKey, d.delimitedstring, d.delimitedvalues, 
    c.items SplitString, 
    c.rn
  FROM dbo.tblRawData d
  CROSS APPLY dbo.Split(d.DelimitedString, ',') c
) s
inner join
(
  SELECT d.RawKey, d.delimitedstring, d.delimitedvalues, 
    c.items SplitValues, 
    c.rn
  FROM dbo.tblRawData d
  CROSS APPLY dbo.Split(d.DelimitedValues, ',') c
) v
  on s.rawkey = v.rawkey
  and s.delimitedstring = v.delimitedstring
  and s.rn = v.rn;

查看SQL Fiddle with Demo
它使用两个子查询生成拆分值列表，然后使用split函数创建的行号连接它们。

因为你是在Sql Server 2008上。你可以使用XML在没有UDF的情况下做到这一点。

;WITH CTE1 AS
( 
    SELECT *
    ,RN= Row_Number() OVER( Partition BY DelemitedString,DelimitedValues,RawKey,TableID ORDER BY TableID)
     FROM 
    (
    SELECT *
    ,DelimitedStringXML = CAST('<d>'+REPLACE(DelemitedString,',','</d><d>')+'</d>' AS XML)
    ,DelimitedValueXML = CAST('<d>'+REPLACE(DelimitedValues,',','</d><d>')+'</d>' AS XML)

     FROM dbo.tblRawData
    ) as t
    Cross Apply
    (
    SELECT y.value('.', 'VARCHAR(30)') AS SplitString FROM DelimitedStringXML.nodes('//d') as  x(y)

    ) as b
)
,CTE2 AS 
(
    SELECT *
    ,RN= Row_Number() OVER( Partition BY DelemitedString,DelimitedValues,RawKey,TableID ORDER BY TableID)
     FROM 
    (
    SELECT *
    ,DelimitedStringXML = CAST('<d>'+REPLACE(DelemitedString,',','</d><d>')+'</d>' AS XML)
    ,DelimitedValueXML = CAST('<d>'+REPLACE(DelimitedValues,',','</d><d>')+'</d>' AS XML)

     FROM dbo.tblRawData
    ) as t
    CROSS APPLY
    (
    SELECT h.value('.', 'VARCHAR(30)') AS SplitValue FROM DelimitedValueXML.nodes('//d') as  g(h)

    ) as c
)

SELECT a.RawKey,a.SplitString,b.SplitValue 
FROM CTE1 as a
INNER JOIN CTE2 as b
    on  a.TableID= b.TableID
    AND a.RN = b.RN

以下是SQLFiddle演示

你可以使用交叉申请多列，如果你把它放在括号和使用“AS”两次。它甚至是别名，以便您可以在查询中进一步使用它们。

SELECT a.*, b,c
b+c as d
FROM a
CROSS APPLY (Select dbo.Split(d.DelimitedValues, ',') AS b) AS b
CROSS APPLY (Select dbo.Split(d.DelimitedString, ',') AS c) AS c
