Problem with "_" starting column names (again

  • I need to select from column names starting with "_" using DBD::InterBase. In interbase (firebird) those columns are not accepted, raising a "Token Unknown" error.  I've tried to make sure ib_dialect is 3 (I read somewhere there are problems with quotes) but it doesn't solved it.
    The database is of dialect 3. I check the dialect first by issuing 'show sql dialect' in isql. 
    Any suggestions?
