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

/*
在这里做逻辑处理，插入或更新操作 ...

*/
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+','

/*
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
