我想創建函數在另一個表中TBL_Sku柱（sku）的值被劃分到任何柱（SKU1，2，3，4，...）（TBL_Sku2）如何將列的值拆分爲SQL Server中的動態列？
柱sku在TBL_SkU ：
ROW1列德：1-Acer Aspire 3811TZG 1GB DDR3-1066 PC8500 Memory Module,SKU:
1GBDDR3-1066-21,&2-Acer Aspire 3811TZG 2GB DDR3-1066 PC8500 Memory Module,SKU: 2GBDDR3-1066-21,&3-Acer Aspire 3811TZG 4GB DDR3-1066 PC8500 Memory Module,SKU: 4GBDDR3-1066-414,&
和在列第2行德：1-SKU: 512MBDDR2-533-1038,Sony VAIO PCG-1J1L 512MB DDR2-533 PC4200 Memory Module,&
和在列第3行德：1-MSI S271 1GB DDR2-533 PC4200 Memory Module,SKU: 1GBDDR2-533-1068,&2-MSI S271 512MB DDR2-533 PC4200 Memory Module,SKU: 512MBDDR2-533-1033,&
輸出：
TBL_Sku2：
id sku1 sku2 sku3 sku4 sku5
--- ----------- ----------------- ------------------- ----------------- ---------
1 1GBDDR3-1066-21 2GBDDR3-1066-21 4GBDDR3-1066-414 Null Null
2 512MBDDR2-533-1038 null null null null
3 1GBDDR2-533-1068 512MBDDR2-533-1033 Null Null Null
我想專業的功能。稍後爲您發送我的代碼。使用在子和CHARINDEX
SP：
ALTER PROCEDURE [dbo].[SP_SpilitSKU]
(@ID int ,@SKU nvarchar(Max))
AS
BEGIN
Declare @YourTable table (ID int,SKU varchar(max))
Insert Into @YourTable values
(@ID,@SKU)
;with cte as (
Select A.ID
,RN = Row_Number() over (Partition By ID Order by RetSeq)
,SKU = LTrim(RTrim(Replace(RetVal,'SKU:','')))
From @YourTable A
Cross Apply (
Select RetSeq = Row_Number() over (Order By (Select null))
,RetVal = LTrim(RTrim(B.i.value('(./text())[1]', 'varchar(max)')))
From (Select x = Cast('<x>'+ replace((Select A.SKU as [*] For XML Path('')),',','</x><x>')+'</x>' as xml).query('.')) as A
Cross Apply x.nodes('x') AS B(i)
) B
Where RetVal like 'SKU:%'
)
INSERT INTO [dbo].[TBL_Sku]

Pivot (max(SKU) For [RN] in ([1],[2],[3],[4],[5],[6])) p
SP：在表

影響數列梅= 15563

錯誤
INSERT語句的選擇列表包含多於插入列表中的項目少。 SELECT值的數量必須與INSERT列的數量相匹配。
我認爲你需要先將字符串轉換爲表格然後進行轉換。我已經做了同樣的事給我5分鐘我會拿出解決方案 –
值在表中@YashveerSingh，列類型是nvarchar（最大） – RedArmy
謝謝@YashveerSingh – RedArmy
