Description

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.
