Generally, you should pad the data after it comes back from the database, not in the database itself.

If you must, though:

SELECT RIGHT('00000' + CAST(column_name AS VARCHAR(5)), 5) AS my_column FROM table_name

select 
  REPLICATE('0', 5 - len(cast(id as varchar)))+cast(id as varchar) as str_id
from 
  mytable
