I like to create a string with bracket if not null, but return a blank string '' if null.

e.g. if the string is 'ABC',  I will like to get (ABC)
if the string is null, I will like to get an empty string ''

How will I do that?

use ISNULL to turn the null value into an empty string, concatenate the str with the brackets to get the bracketed string ... if the value the was null, concatenation will be null still.  e.g.
    select isnull('('+str+')',''), str
    from (select 'abc' as str union all select null)v
