select len(' hello') -> 6 because it has leading space
select len(' hello ')-> 6 it counts leading space ignores trailing space.
select len(' hello') -> 6 because it has leading space
select len(' hello ')-> 6 it counts leading space ignores trailing space.
select len(ltrim(rtrim(' hello '))-> 5 it removes leading and trailing spaces then counts characters.
