T-SQL Split Word into characters

Here you have it:

create table #words (
  character varchar(1)
)

declare @test varchar(10)
select @test = 'QWERTY'

declare @count int, @total int
select @total = len(@test), @count = 0

while @count <= @total
begin
  insert into #words select substring(@test, @count, 1)
  select @count = @count + 1
end

select * from #words

drop table #words

Declare @word nvarchar(max)
Select @word = 'Hello This is the test';

with cte (Number)as 
(Select 1
union all 
select Number +1 From cte  where number <len(@word)
)
select * from Cte Cross apply (Select SUBSTRING(@word,number,1 ) ) as J(Letter)

Do it like this:

select substring(a.b, v.number+1, 1) 
from (select 'QWERTY AnotherWord' b) a
join master..spt_values v on v.number < len(a.b)
where v.type = 'P'
