If your database compatibility level is 70 or 80, an empty string (length
zero) is considered equal to a string containing zero or more spaces.

Is it safe to assume that an empty string (which contains any number of
space characters) is always equal to ''? Or should I go for
ltrim(rtrim(@string))=0?
