maxdb_stmt->affected_rows -- Returns the total number of rows changed, deleted, or

Description

maxdb_stmt_affected_rows() returns the number of rows affected
by INSERT, UPDATE, or DELETE query. If the last query was invalid or the
number of rows can not determined, this function will return -1.
Return Values
An integer greater than zero indicates the number of rows affected or retrieved.
Zero indicates that no records where updated for an UPDATE/DELETE statement, no
rows matched the WHERE clause in the query or that no query has yet been executed.
-1 indicates that the query has returned an error or the number of rows can not determined.
Example
例子 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();
}
/* create temp table */
$maxdb->query("CREATE TABLE temp.mycity LIKE hotel.city");
$query = "INSERT INTO temp.mycity SELECT * FROM hotel.city WHERE state LIKE ?";
/* prepare statement */
if ($stmt = $maxdb->prepare($query)) {
/* Bind variable for placeholder */
$code = 'N%';
$stmt->bind_param("s", $code);
/* execute statement */
$stmt->execute();
printf("rows inserted: %d\n", $stmt->affected_rows);
/* close statement */
$stmt->close();
}
/* close connection */
$maxdb->close();
?>

例子 2. Procedural style
<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
/* create temp table */
maxdb_query($link, "CREATE TABLE temp.mycity LIKE hotel.city");
$query = "INSERT INTO temp.mycity SELECT * FROM hotel.city WHERE state LIKE ?";
/* prepare statement */
if ($stmt = maxdb_prepare($link, $query)) {
/* Bind variable for placeholder */
$code = 'N%';
maxdb_stmt_bind_param($stmt, "s", $code);
/* execute statement */
maxdb_stmt_execute($stmt);
printf("rows inserted: %d\n", maxdb_stmt_affected_rows($stmt));
/* close statement */
maxdb_stmt_close($stmt);
}
/* close connection */
maxdb_close($link);
?>
