(no version information, might be only in CVS)

PDOStatement::setFetchMode --  Set the default fetch mode for this statement

说明

警告

本函数是实验性的。本函数的行为，包括函数名称以及其它任何关于本函数的文档可能会在没有通知的情况下随 PHP 以后的发布而改变。使用本函数风险自担。

参数

mode

The fetch mode must be one of the PDO_FETCH_* constants.

返回值

例

例子 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();
}
?>

上例将输出：

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