Example

Пример 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.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();
?>

Пример 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);
?>

The above examples would produce the following output:

Records: 25 Duplicates: 0 Warnings: 0
