= 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.t1 LIKE hotel.city");

/* INSERT INTO .. SELECT */
$maxdb->query("INSERT INTO temp.t1 SELECT * FROM hotel.city");
printf("%s\n"$maxdb->info);

/* 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.t1 LIKE hotel.city");

/* INSERT INTO .. SELECT */
maxdb_query($link"INSERT INTO temp.t1 SELECT * FROM hotel.city");
printf("%s\n"maxdb_info($link));

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