Answer 1

If the datatype of name column is varchar then don’t need to use rtrim function the right side spaces will be automatically trim. use only LTRIM only.

update tablename
set    name = ltrim(name)
where  <condition>;

Run this see the how it trims the right spaces automatically.

DECLARE @mytb table
(
name varchar(20)
);

INSERT INTO @mytb VALUES ('   stackoverflow         ');

SELECT len(name) from @mytb;

SELECT ltrim(name),len(ltrim(name)) from @mytb;
