    Example #1 Stil obiect-orientat

    <?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");

    $city = "'s Hertogenbosch";

    /* this query will fail, cause we didn't escape $city */
    if (!$maxdb->query("INSERT into temp.mycity VALUES ('11111','$city','NY')")) {
           printf("Error: %s\n", $maxdb->sqlstate);
    }

    $city = $maxdb->real_escape_string($city);

    /* this query with escaped $city will work */
    if ($maxdb->query("INSERT into temp.mycity VALUES ('22222','$city','NY')")) {
           printf("%d Row inserted.\n", $maxdb->affected_rows);
    }

    $maxdb->close();
    ?>

    Example #2 Stil procedural

    <?php
    $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");

    $city = "'s Hertogenbosch";

    /* this query will fail, cause we didn't escape $city */
    if (!maxdb_query($link, "INSERT into temp.mycity VALUES ('11111','$city','NY')")) {
           printf("Error: %s\n", maxdb_sqlstate($link));
    }

    $city = maxdb_real_escape_string($link, $city);

    /* this query with escaped $city will work */
    if (maxdb_query($link, "INSERT into temp.mycity VALUES ('22222','$city','NY')")) {
           printf("%d Row inserted.\n", maxdb_affected_rows($link));
    }

    maxdb_close($link);
    ?>

    Exemplul de mai sus va afișa ceva similar cu:

    Warning: maxdb_query(): -5016 POS(43) Missing delimiter: ) <...>
Error: 42000
1 Row inserted.
