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.

<?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";
}
?>
