An integer greater than zero indicates the number of rows affected or retrieved.

Example
Esempio 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(); }
/* create temp table */ $maxdb->query("CREATE TABLE temp.mycity LIKE hotel.city");
$query = "INSERT INTO temp.mycity SELECT * FROM hotel.city WHERE state LIKE ?";
/* prepare statement */ if ($stmt = $maxdb->prepare($query)) {
/* Bind variable for placeholder */ $code = 'N%'; $stmt->bind_param("s", $code); /* execute statement */ $stmt->execute();
printf("rows inserted: %d\n", $stmt->affected_rows);
/* close statement */ $stmt->close(); }
/* close connection */ $maxdb->close(); ?>

Esempio 2. Procedural style
<?php $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s\n", maxdb_connect_error()); exit(); }
/* create temp table */ maxdb_query($link, "CREATE TABLE temp.mycity LIKE hotel.city");
$query = "INSERT INTO temp.mycity SELECT * FROM hotel.city WHERE state LIKE ?";
/* prepare statement */ if ($stmt = maxdb_prepare($link, $query)) {
/* Bind variable for placeholder */ $code = 'N%'; maxdb_stmt_bind_param($stmt, "s", $code); /* execute statement */ maxdb_stmt_execute($stmt);
printf("rows inserted: %d\n", maxdb_stmt_affected_rows($stmt));
/* close statement */ maxdb_stmt_close($stmt); }
/* close connection */ maxdb_close($link); ?>
