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";
  }
}
catch (PDOException $e) {
  print $e->getMessage();
}
?>

The above example will output:

apple   red     150
banana  yellow  250
orange  orange  300
kiwi    brown   75
lemon   yellow  25
pear    green   150
watermelon      pink    90
