maxdb_stmt_affected_rows

(no version information, might be only in CVS)

maxdb_stmt->affected_rows -- Returns the total number of rows changed, deleted, or inserted by the last executed statement

## Description

Procedural style :

mixed maxdb_stmt_affected_rows ( resource stmt )

Object oriented style (property):

class stmt {
mixed affected_rows
}

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

Przykład 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();
?>`

Przykład 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);
?>`

The above examples would produce the following output:

    rows inserted: 4
