Attribution - For Handles
 
 
- Two kinds of attributes: Handle Attributes and Method Attributes
- A DBI handle is a reference to a hash
- Handle Attributes can be read or set by accessing the hash via the reference
- 
$h->{AutoCommit} = 0;
 
 $autocomitting = $h->{AutoCommit};
 
 
- Some attributes are read-only
- 
$sth->{NUM_OF_FIELDS} = 42; # fatal error
 
 
 
- Using an unknown attribute triggers a warning
- 
		$sth->{AutoCommat} = 42; # triggers a warning
 
 $autocomitting = $sth->{AutoCommat}; # triggers a warning- 
- driver-private attributes (which have lowercase names) do not trigger a warning
