maxdb_num_rows

Gets the number of rows in a result (PECL maxdb:1.0-7.6.00.38)
int maxdb_num_rows ( resource result )

Procedural style:

Object oriented style (property):

maxdb {
  int 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 1230. 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 1231. 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.
