Statement Handle Attributes

This section describes attributes specific to statement handles. Most of these attributes are read-only.

Changes to these statement handle attributes do not affect any other existing or future statement handles.

Attempting to set or get the value of an unknown attribute is fatal, except for private driver-specific attributes (which all have names starting with a lowercase letter).

For example:

... = $h->{NUM_OF_FIELDS};    # get/read

Note that some drivers cannot provide valid values for some or all of these attributes until after $sth->execute has been called.

See also finish to learn more about the effect it may have on some attributes.
