1.游标方式

 
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+','

/*

*/ 
END 
SELECT @Results
