Question

I need a function in sql server to insert a space in each position of an input string.
For example, if the input of the function is

"example"

the output of the function should be

word1   word2
e       xample
ex      ample
exa     mple
exam    ple
examp   le
exampl  e

Answer 1

declare @S varchar(20) = 'example'

select left(@S, number) as word1,
       stuff(@S, 1, number, '') as word2
from master..spt_values
where type = 'P' and
      number between 1 and len(@S)-1

Or like this if you want one column with the space inserted:

select stuff(@S, number, 0, ' ') as word
from master..spt_values
where type = 'P' and
      number between 2 and len(@S)
