maxdb_num_rows
(no version information, might be only in CVS) maxdb_num_rows --
Gets the number of rows in a result
DescriptionProcedural style: mixed maxdb_num_rows ( resource result ) Object oriented style (property): class maxdb { mixed 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.
ExampleExample 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);
?>
