PHP Manual


maxdb_num_rows

maxdb::num_rows

(PECL maxdb >= 1.0)

maxdb_num_rows -- maxdb::num_rowsGets the number of rows in a result

Description

Procedural style

int maxdb_num_rows ( resource $result )

Object oriented style

int $maxdb->num_rows;

Returns the number of rows in the result set.

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.

Return Values

Returns number of rows in the result set.

Note:

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

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();
}

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();
?>

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();
}

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 example will output something similar to:

Result set has 15 rows.
