NAME

       DBD::Firebird::TableInfo::Basic - A base class for lowest-common denominator Firebird
       table_info() querying.

SYNOPSIS

           # Add support for a hypothetical IB derivative
           package DBD::Firebird::TableInfo::HypotheticalIBDerivative

           @ISA = qw(DBD::Firebird::TableInfo::Basic);

           # What table types are supported?
           sub supported_types {
               ('SYSTEM TABLE', 'TABLE', 'VIEW', 'SPECIAL TABLE TYPE');
           }

           sub table_info {
               my ($self, $dbh, $table, @types) = @_;
           }

INTERFACE

       list_catalogs
               $ti->list_catalogs($dbh);  # $dbh->table_info('%', '', '')

           Returns a statement handle with an empty result set, as IB does not support the DBI
           concept of catalogs. (Rule 19a)

       list_schema
               $ti->list_schema($dbh);    # $dbh->table_info('', '%', '')

           Returns a statement handle with an empty result set, as IB does not support the DBI
           concept of schema. (Rule 19b)

       list_tables
               $ti->list_tables($dbh, $table, @types); # $dbh->table_info('', '',
                                                       #                  'FOO%',
                                                       #                  'TABLE,VIEW');

           Called in response to $dbh->table_info($cat, $schem, $table, $types).  $cat and $schem
           are presently ignored.

           This is the workhorse method that must return an appropriate statement handle of
           tables given the requested $table pattern and @types.  A blank $table pattern means
           "any table," and an empty @types list means "any type."

           @types is a list of user-supplied, requested types.  "DBD::Firebird::db::table_info"
           will normalize the user-supplied types, stripping quote marks, uppercasing, and
           removing duplicates.

       list_types
               $tbl_info->list_types($dbh);  # $dbh->table_info('', '', '', '%')

           Called in response to $dbh->table_info('', '', '', '%'), returning a statement handle
           with a TABLE_TYPE column populated with the results of supported_types.  (Rule 19c)

           Normally not overridden.  Override supported_types, instead.

       supported_types
               $tbl_info->supported_types($dbh);

           Returns a list of supported DBI TABLE_TYPE entries.  The default implementation
           supports 'TABLE', 'SYSTEM TABLE' and 'VIEW'.

           This method is called by the default implementation of "list_types".
