Examples

Example #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";
}
?>

The above example will output:

cat Pook
gold fish Bubbles
budgerigar Gizmo
goat Rickety Ride
