> Currently if we see an asterisk in an identifier, we translate it to an identifier name segment called "\*". If there happens to be a table, column or field called "*" we're sunk.
> Star can only validly occur in the SELECT clause (not in FROM or WHERE). Examples: {{select emp.\* from emp}}, {{select x from sales.\*}}, {{select 1 from emp where emp.\* is not null}}.
> This task is to test with tables, columns, fields called "*", and use a special value in SqlIdentifier. Maybe the empty string would work. Names cannot be empty.
