- Getting data about your data:
- 
$sth = $dbh->table_info( ... )
 - 
- Now allows parameters to qualify which tables you want info on
 $sth = $dbh->column_info($cat, $schema, $table, $col);- 
- Returns information about the columns of a table
 $sth = $dbh->primary_key_info($cat, $schema, $table);- 
- Returns information about the primary keys of a table
 @keys = $dbh->primary_key($cat, $schema, $table);- 
- Simpler way to return information about the primary keys of a table
