All of the data selected is returned in the result object.
At this point you need to iterate through it to get the data:
Here's an example:
for ( my $tuple = 0 ; $tuple < $result->ntuples ; $tuple++ )
{
for ( my $field = 0 ; $field < $result->nfields ; $field++ )
{
printf( "%d: %s = %s\n", $tuple, $result->fname( $field ),
$result->getvalue( $tuple, $field ) );
}
}
