The use of maxdb_num_rows() depends on whether you use buffered or unbuffered result sets. In case you use unbuffered resultsets maxdb_num_rows() will not correct the correct number of rows until all the rows in the result have been retrieved.

Returns number of rows in the result set.

Замечание: If the number of rows is greater than maximal int value, the number will be returned as a string.

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();
}

if ($result = $maxdb->query("SELECT cno, name FROM hotel.customer ORDER BY name")) {

   /* determine number of rows result set */
   $row_cnt = $result->num_rows;

   printf("Result set has %d rows.\n", $row_cnt);

   /* close result set */
   $result->close();
}

/* 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();
}

if ($result = maxdb_query($link, "SELECT cno, name FROM hotel.customer ORDER BY name")) {

   /* determine number of rows result set */
   $row_cnt = maxdb_num_rows($result);

   printf("Result set has %d rows.\n", $row_cnt);

   /* close result set */
   maxdb_free_result($result);
}

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

The above examples would produce the following output:

Result set has 15 rows.
