# PDOStatement->fetchColumn()

(PHP 5 >= 5.1.0, PECL pdo:0.9-1.0.3)

PDOStatement->fetchColumn() — Returns a single column from the next row of a result set

### Description

PDOStatement
string fetchColumn ([ int `$column_number` ] )

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

### Parameters

`column_number`

  0-indexed number of the column you wish to retrieve from the row. If no value is supplied, PDOStatement->fetchColumn() fetches the first column.

### Return Values

PDOStatement->fetchColumn() returns a single column in the next row of a result set.

Warning

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

### Examples

Example#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");
?>`

The above example will output:

    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
