Returns a single column from the next row of a result set or `FALSE` if there are no more rows.

Warnung

There is no way to return another column from the same row if you use PDOStatement::fetchColumn() to retrieve data.

### Beispiele

Beispiel #1 Return first column of the next row

`<?php
$sth = $dbh->prepare("SELECT name, colour FROM fruit");
$sth->execute();
/* Fetch the first column from the next row in the result set */
print("Fetch the first column from the next row in the result set:\n");
$result = $sth->fetchColumn();
print("name = $result\n");
print("Fetch the second column from the next row in the result set:\n");
$result = $sth->fetchColumn(1);
print("colour = $result\n");
?>`

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

    Fetch the first column from the next row in the result set:
    name = lemon
    Fetch the second column from the next row in the result set:
    colour = red
