Answer 1

Depending on your database you can use trim() , ltrim() / rtrim() , or replace() :

select replace(name, ' ', '')
select trim(name, ' ')
select ltrim(rtrim(name))

Answer 2

You can use the LTRIM and RTRIM functions to remove trailing and leading spaces.

SELECT
    RTRIM(LTRIM(name)) AS name
FROM yourTable
