将逗号分隔的值插入到表的多个列中 [英] Insert comma seperated values into multiple columns of a table

问题描述

我想在数据表中插入逗号分隔的值
例如
逗号分隔的字符串，例如"123，char，456，vargh"
必须像使用storeprocedure一样插入表中

i want to insert comma separated values into datatable table
for example
the comma saperated string like ''123,char,456,vargh''
has to be inserted into table like using storeprocedure

col1 col2,col3 col4
123  char  456  vargh

插入单个列中，但我需要上述过程

在此先感谢

inserting into a single column i know but i need above process

thanks in advance

推荐答案

试试这个

Hi,
try this one

SELECT col1 + '','' + col2 + '','' + col3 + '','' + col4 From tableName

你好朋友...

对于您的解决方案，您需要按照以下步骤操作...

1)首先像这样在数据库中创建一个函数...

Hello Friend...

For your solution you need to follow this steps...

1) First Create one Function in your database like this...

ALTER FUNCTION DBO.SPLIT(@STRING VARCHAR(8000), @DELIMITER CHAR(1))       
    RETURNS @TEMPTABLE TABLE (ID INT IDENTITY(1,1),ITEMS VARCHAR(8000))       
    AS       
    BEGIN       
        DECLARE @IDX INT       
        DECLARE @SLICE VARCHAR(8000)       
          
        SELECT @IDX = 1       
            IF LEN(@STRING)<1 OR @STRING IS NULL  RETURN       
          
        WHILE @IDX!= 0       
        BEGIN       
            SET @IDX = CHARINDEX(@DELIMITER,@STRING)       
            IF @IDX!=0       
                SET @SLICE = LEFT(@STRING,@IDX - 1)       
            ELSE       
                SET @SLICE = @STRING       
              
            IF(LEN(@SLICE)>0)  
                INSERT INTO @TEMPTABLE(ITEMS) VALUES(@SLICE)       
      
            SET @STRING = RIGHT(@STRING,LEN(@STRING) - @IDX)       
            IF LEN(@STRING) = 0 BREAK       
        END   
    RETURN       
    END 

2)现在您需要像这样调用插入查询....

2) Now you need to call insert query like this....

INSERT INTO TABLENAME 
SELECT * FROM (
	SELECT TOP(4) id,items FROM	dbo.split('123,char,456,vargh',',')
) up
PIVOT (MAX(ITEMS) FOR ID IN ([1],[2],[3],[4])) as pvt
GO
