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

Trim with many cases

--id = 100 101 102 103 104 105 106 107 108 109 110 111
select right(id,2)+1  from ordertbl -- 1 2 3 4 5 6 7 8 9 10 11  -- last     two positions are taken

select LEFT('BOB', LEN('BOB')-1) -- BO

select LEFT('BOB*',1) --B
select LEFT('BOB*',2) --BO
