Example

Example 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");

/* a remarkable city in Wales */
$query = "INSERT INTO temp.mycity (zip, name) VALUES('11111',
       'Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch')";

$maxdb->query($query);

printf ("Number of warning: %d\n", $maxdb->warning_count);

/* close connection */
$maxdb->close();
?>

Example 2. Procedural style

<?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");

/* a remarkable long city name in Wales */
$query = "INSERT INTO temp.mycity (zip, name) VALUES('11111',
       'Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch')";

maxdb_query($link, $query);

printf ("Number of warning: %d\n", maxdb_warning_count($link));

/* close connection */
maxdb_close($link);
?>

The above examples would produce the following output: 

Warning: maxdb_query(): -8004 POS(62) Constant must be compatible with column type and length <...>
Number of warning: 0
