csv_* All other attributes that start with csv_ and are not described above will be passed to Text::CSV_XS (without the csv_ prefix). these extra options are most likely to be only useful for reading (select) handles. Examples: $dbh->{csv_allow_whitespace} = 1; $dbh->{csv_allow_loose_quotes} = 1; $dbh->{csv_allow_loose_escapes} = 1; See the Text::CSV_XS documentation for the full list and the documentation.
