Példa 1. Procedural style

`<?php
$link = maxdb_connect("localhost", "MONA", "RED");
/* check connection */
if (!$link) {
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");
$stmt = maxdb_prepare($link, "INSERT INTO temp.mycity VALUES (?, ?, ?)");
maxdb_stmt_bind_param($stmt, 'sss', $zip, $name, $state);
$zip = '11111';
$name = 'Georgetown';
$state = 'NY';
/* execute prepared statement */
maxdb_stmt_execute($stmt);
printf("%d Row inserted.\n", maxdb_stmt_affected_rows($stmt));
/* close statement and connection */
maxdb_stmt_close($stmt);
/* Clean up table CountryLanguage */
maxdb_query($link, "DELETE FROM temp.mycity WHERE name='Georgetown'");
printf("%d Row deleted.\n", maxdb_affected_rows($link));
/* close connection */
maxdb_close($link);
?>`

The above examples would produce the following output:

    1 Row inserted.
    1 Row deleted.
