Try this
CREATE FUNCTION [dbo].[SplitString]
(@instring VARCHAR(MAX))
RETURNS @Splitstring TABLE(Columnslist
VARCHAR(MAX))
AS
BEGIN
DECLARE    
         @len
INT,
         @i
INT=1,
         @N
INT=1,
         @instring
VARCHAR(MAX),
         @instrings
VARCHAR(MAX)= @input +
SET @len = LEN(@instrings)
          WHILE @i<=@len
          BEGIN
            IF
SUBSTRING(@instrings,@i,1)='/'
             BEGIN
SET @instring = SUBSTRING(@instrings,@N,@i-@N)
INSERT INTO @SplitString(Columnslist)
SELECT @instring
SET @N = @i+1;
             END
             SET
@i = @i+1;
          END
RETURN ;
END
GO
