1.游标方式

复制代码 代码如下:

DECLARE @Data NVARCHAR(max)

SET @Data='1,tanw,2,keenboy' --Id,Name

DECLARE @dataItem NVARCHAR(100)

DECLARE data_cursor CURSOR FOR (SELECT * FROM split(@Data,';'))

OPEN data_cursor

FETCH NEXT FROM data_cursor INTO @dataItem

WHILE @@FETCH_STATUS=0

BEGIN

DECLARE @Id INT

DECLARE @Name NVARCHAR(50)

DECLARE dataItem_cursor CURSOR FOR (SELECT * FROM split(@dataItem,','))

OPEN dataItem_cursor

FETCH NEXT FROM dataItem_cursor INTO @Id

FETCH NEXT FROM dataItem_cursor INTO @Name

CLOSE dataItem_cursor

DEALLOCATE dataItem_cursor

/*

*/

END

CLOSE data_cursor

DEALLOCATE data_cursor

2.While方式

复制代码 代码如下:

DECLARE @Data NVARCHAR(max)

SET @Data='tanw,keenboy' --Id,Name

DECLARE @Temp TABLE

(

Id INT IDENTITY(1,1),

Name NVARCHAR(50)

)

DECLARE @Id INT

DECLARE @Name NVARCHAR(50)

DECLARE @Results NVARCHAR(MAX) SET @Results=''

INSERT INTO @Temp SELECT (SELECT * FROM split(@Data,';'))

WHILE EXISTS(SELECT * FROM @Temp)

BEGIN

SELECT TOP 1 @Id=Id,@Name=Name from @Temp

DELETE FROM @Temp where [id] = @Id

SET @Results=@Results+@Name+','

www.jb51.net

/*

在这里做逻辑处理，插入或更新操作 ...

*/

END

SELECT @Results

如果是简单单表批量插入操作的，上面方法大可不必要
