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

@teejay solution is great. But the code below can be more understandable:

declare @X nvarchar(max)='BOB *'

set @X=replace(@X,' ','^')

set @X=replace(@X,'*',' ')

set @X= ltrim(rtrim(@X))

set @X=replace(@X,'^',' ')
