Examples

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();
}

/* 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();
?>

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();
}

/* 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);
?>

The above example will output something similar to:

rows inserted: 4
