SQL Server TRIM character

Question

I have the following string: \'BOB*\', how do I trim the * so it shows up as \'BOB\'

I tried the RTRIM(\'BOB*\',\'*\') but does not work as says needs only 1 paramet

Answer 1

Solution for one char parameter:

rtrim('0000100','0') -> select left('0000100',len(rtrim(replace('0000100','0',' '))))

ltrim('0000100','0') -> select right('0000100',len(replace(ltrim(replace('0000100','0',' ')),' ','.')))
