-- 方法一:利用字符串截取拆分数组字符串

-- =============================================

CREATE PROCEDURE SP_ParameterArray 

 @UserName VARCHAR(10),

 @StrArray VARCHAR(800)

AS

DECLARE @P INT

DECLARE @C INT

DECLARE @Nums INT

SET @P=1 

SET @C=1

BEGIN TRANSACTION     

Set NOCOUNT ON

 CREATE TABLE #t_info

 (

   UserName VARCHAR(10),

   Nums INT

 )

 SET @C=CHARINDEX(',',@StrArray,@P+1)

 SET @Nums=CAST(SUBSTRING(@StrArray,@P,@C-@P) AS INT)

 INSERT INTO #t_info(UserName,Nums) VALUES(@UserName,@Nums)

 SET @P=@C

 WHILE (@P+1< LEN(@StrArray))

  BEGIN

   SET @C=CHARINDEX(',',@StrArray,@P+1)

   IF(@C> 0)

    BEGIN

     SET @Nums=CAST (SUBSTRING(@StrArray,@P+1,@C-@P-1) AS INT)

     INSERT INTO #t_info(UserName,Nums) VALUES(@UserName,@Nums)

     SET @P=@C

    END

   ELSE

    BREAK  

  END

SET @Nums=CAST(SUBSTRING(@StrArray,@P+1,LEN(@StrArray)-@P) AS INT)

INSERT INTO #t_info(UserName,Nums) VALUES(@UserName,@Nums)

SELECT * FROM #t_info

DROP TABLE #t_info

SET NOCOUNT OFF

IF @@ERROR=0

 BEGIN

  COMMIT TRANSACTION

 END

ELSE

 BEGIN

   ROLLBACK TRANSACTION

 END

GO

 

方法二：利用OpenXML 效率更高

-- 方法二:利用OpenXML 效率更高

-- @XML_Array='<Array><PA Nums="1"></PA><PA Nums="2"></PA><PA Nums="3"></PA><PA Nums="4"></PA></Array>'

-- =============================================

CREATE PROCEDURE [dbo].[SP_ParameterArray2] 

 @UserName VARCHAR(10),

 @XML_Array nvarchar(500)

AS

BEGIN 

IF (@XML_Array IS NULL OR LEN(LTRIM(RTRIM(@XML_Array))) = 0) 

 RETURN 

CREATE TABLE #t_info(UserName VARCHAR(10),Nums INT)

DECLARE @IdHandel INT

EXEC sp_xml_preparedocument @IdHandel OUTPUT, @XML_Array

INSERT INTO #t_info(UserName,Nums)

SELECT @UserName,N.Nums 

FROM OPENXML(@IdHandel,'/Array/PA') WITH(Nums INT) AS N

WHERE N.[Nums] IS NOT NULL

EXEC sp_xml_removedocument @IdHandel

SELECT * FROM #t_info

DROP TABLE #t_info

END
