NAME
       DBD::Firebird::TableInfo::Basic - A base class for lowest-common denominator Interbase 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".
