访问PHP/MySQL中最后创建的行 [英] Accessing last created row in PHP/MySQL

问题描述

如何使用PHP/MySQL访问刚插入数据库的行?

How to access the row which has just been inserted into a DB with PHP/MySQL?

我有:

    $sql = 'INSERT INTO `jos_db`.`jos_sections` (`id`,  `name`) VALUES (NULL, \'foo\')';
    mysql_query($sql, $dbi);

    bar();

如何访问bar()中的新行?

How do I access the new row in bar()?

推荐答案

如果"id"列是自动递增的，则可以使用

If you 'id' column is an auto-increment, you can use mysql_insert_id :

检索为 前一个AUTO_INCREMENT列 INSERT查询.

Retrieves the ID generated for an AUTO_INCREMENT column by the previous INSERT query.

手册中给出的示例如下所示:

The example given in the manual looks like this :

$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$link) {
    die('Could not connect: ' . mysql_error());
}
mysql_select_db('mydb');

mysql_query("INSERT INTO mytable (product) values ('kossu')");
printf("Last inserted record has id %d\n", mysql_insert_id());
