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
