Example#1 Setting the fetch mode
The following example demonstrates how PDOStatement->setFetchMode() changes the default fetch mode for a PDOStatement object.
<?php
$sql = 'SELECT name, colour, calories FROM fruit';
try {
$stmt = $dbh->query($sql);
$result = $stmt->setFetchMode(PDO::FETCH_NUM);
while ($row = $stmt->fetch()) {
print $row[0] . "\t" . $row[1] . "\t" . $row[2] . "\n";

print $e->getMessage();
}
?>
上例将输出：
