# db2_result

(PECL ibm_db2 >= 1.0.0)

db2_result — Returns a single column from a row in the result set

### Beschreibung

mixed db2_result ( resource `$stmt` , mixed `$column` )

Use db2_result() to return the value of a specified column in the current row of a result set. You must call db2_fetch_row() before calling db2_result() to set the location of the result set pointer.

### Parameter-Liste

`stmt`

  A valid stmt resource.

`column`

  Either an integer mapping to the 0-indexed field in the result set, or a string matching the name of the column.

### Rückgabewerte

Returns the value of the requested field if the field exists in the result set. Returns NULL if the field does not exist, and issues a warning.

### Beispiele

Beispiel #1 A db2_result() example

The following example demonstrates how to iterate through a result set with db2_fetch_row() and retrieve columns from the result set with db2_result().

`<?php
$sql = 'SELECT name, breed FROM animals WHERE weight < ?';
$stmt = db2_prepare($conn, $sql);
db2_execute($stmt, array(10));
while (db2_fetch_row($stmt)) {
$name = db2_result($stmt, 0);
$breed = db2_result($stmt, 'BREED');
print "$name $breed";
}
?>`

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

    cat Pook
    gold fish Bubbles
    budgerigar Gizmo
    goat Rickety Ride
