Answer 1

像这样做:

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

Answer 2

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)
