This is an alternative for "Split Any Delimited String in SQL"
It's still not a very good solution ("any" is most inaccurate), but here's a Recursive Common Table Expression way to do it.
CREATE FUNCTION dbo.fnSimpleSplit 
( @InputString NVARCHAR(MAX)
, @Delimiter   NCHAR(1)
  -- SELECT * FROM dbo.fnSimpleSplit ( 'Apple, Mango, Orange, Pineapple' , ',' )

  WITH cte AS
    SELECT CAST(NULL AS NVARCHAR(MAX)) val , @InputString + @Delimiter s , CHARINDEX(@Delimiter,@InputString) offset
    SELECT SUBSTRING(s,1,offset-1) , SUBSTRING(s,offset+1,LEN(s)) , CHARINDEX(@Delimiter,s,offset+1)-offset
    FROM cte
    WHERE offset>0
  SELECT val
  FROM cte

Another alternative that will be available in Sql Server 2016/Azure Db:

SELECT value FROM OPENJSON('[1,4,6,9]')

You just need to surround it with brackets. Unfortunately it will work only for comma separated strings.
