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 table doesn't return a resultset */

if ($maxdb->query("CREATE TABLE temp.mycity LIKE hotel.city") === TRUE) {

   printf("Table mycity successfully created.\n");

}



/* Select queries return a resultset */

if ($result = $maxdb->query("SELECT name FROM hotel.city")) {

   printf("Select returned %d rows.\n", $result->num_rows);



   /* free result set */

   $result->close();

}



/* If we have to retrieve large amount of data we use MAXDB_USE_RESULT */

if ($result = $maxdb->query("SELECT * FROM hotel.city", MAXDB_USE_RESULT)) {

   $result->close();

}



$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 table doesn't return a resultset */

if (maxdb_query($link, "CREATE TABLE temp.mycity LIKE hotel.city") === TRUE) {

   printf("Table mycity successfully created.\n");

}



/* Select queries return a resultset */

if ($result = maxdb_query($link, "SELECT name FROM hotel.city")) {

   printf("Select returned %d rows.\n", maxdb_num_rows($result));



   /* free result set */

   maxdb_free_result($result);

}



/* If we have to retrieve large amount of data we use MAXDB_USE_RESULT */

if ($result = maxdb_query($link, "SELECT * FROM hotel.city", MAXDB_USE_RESULT)) {

   maxdb_free_result($result);

}



maxdb_close($link);

?>

The above example will output something similar to:

Table mycity successfully created.
Select returned 25 rows.
