maxdb_num_rows
(PECL maxdb:1.0-7.6.00.38)
maxdb_num_rows — Gets the number of rows in a result
Description
Procedural style:
int maxdb_num_rows
( resource $result
)
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
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
if ($result = $maxdb->query("SELECT cno, name FROM hotel.customer ORDER BY name")) {
$row_cnt = $result->num_rows;
printf("Result set has %d rows.\n", $row_cnt);
$result->close();
}
$maxdb->close();
?>
Example #2 Procedural style
<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
if ($result = maxdb_query($link, "SELECT cno, name FROM hotel.customer ORDER BY name")) {
$row_cnt = maxdb_num_rows($result);
printf("Result set has %d rows.\n", $row_cnt);
maxdb_free_result($result);
}
maxdb_close($link);
?>
The above example will output
something similar to:
