Beispiel #1 Object oriented style
<?php

$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}$maxdb->query("CREATE TABLE temp.mycity LIKE hotel.city");
$maxdb->query("INSERT INTO temp.mycity SELECT * FROM hotel.city");$query = "SELECT name, zip FROM temp.mycity ORDER BY name";
if ($stmt = $maxdb->prepare($query)) {
/* drop table */
$maxdb->query("DROP TABLE temp.mycity");
/* execute query */
$stmt->execute();
printf("Error: %s.\n", $stmt->error);
/* close statement */
$stmt->close();
}/* close connection */
$maxdb->close();
?>Beispiel #2 Procedural style
<?php
/* Open a connection */
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}maxdb_query($link, "CREATE TABLE temp.mycity LIKE hotel.city");
maxdb_query($link, "INSERT INTO temp.mycity SELECT * FROM hotel.city");$query = "SELECT name, zip FROM temp.mycity ORDER BY name";
if ($stmt = maxdb_prepare($link, $query)) {
/* drop table */
maxdb_query($link, "DROP TABLE temp.mycity");
/* execute query */
maxdb_stmt_execute($stmt);
printf("Error: %s.\n", maxdb_stmt_error($stmt));
/* close statement */
maxdb_stmt_close($stmt);
}/* close connection */
maxdb_close($link);
