SQL Split Function and Ordering Issue?

Question

I have the following Split function,

ALTER FUNCTION [dbo].[Split](@String varchar(8000), @Delimiter char(1))     
                returns @tempt         


        

Answer 1

declare @Version nvarchar(3000)
declare @Delimiter char(1) = ','
declare @result nvarchar(3000)
set @Version = 'Terça-feira, Quarta-feira, Sexta-feira, Segunda-feira';

with V as (select value v, Row_Number() over (order by (select 0)) n 
    from String_Split(@Version, @Delimiter)
)
    SELECT @result = STUFF((SELECT ', ' + RTRIM(LTRIM(v))
      FROM V
      ORDER BY CASE RTRIM(LTRIM(v))
            WHEN 'Segunda-feira' then 1 
            WHEN 'Terça-feira' then 2
            WHEN 'Quarta-feira' then 3 
            WHEN 'Quinta-feira' then 4 
            WHEN 'Sexta-feira' then 5
           END FOR XML PATH('')), 1, LEN(@Delimiter), '')
PRINT @result
