SQL 根据指定字符拆分字符串

 

CREATE FUNCTION [dbo].[F_StringSplit]

(

    @STR NVARCHAR(MAX)='',

    @SPLITER NVARCHAR(20)='')

    RETURNS @TB TABLE(TB_V NVARCHAR(200))

        

    AS 

    

    

    BEGIN

        DECLARE @NUM INT, @POS INT,@NEXT_POS INT

        SET @NUM=0

        SET @POS=1

        WHILE (@POS <=LEN(@STR))

        BEGIN

            SELECT @NEXT_POS=CHARINDEX(@SPLITER,@STR,@POS)

            IF (@NEXT_POS=0 OR @NEXT_POS IS NULL)

            --BEGIN

                SELECT @NEXT_POS=LEN(@STR)+1

                

                INSERT INTO @TB VALUES(RTRIM(LTRIM(SUBSTRING(@STR,@POS,@NEXT_POS-@POS))))

                

                SELECT @POS=@NEXT_POS +1

            --END

            

        END

        RETURN

    END

 

调用：

select * from  DBO.F_StringSplit('5,6,2,3,',',')
