根据 PHP 文档，mysql_insert_id 从 mysql 表中获取最后插入的 id。
我的问题是，如果我有一个每秒向数据库插入超过 2 行的网站，我可以使用 mysql_insert_id 并获得我在 中引用的正确 ID INSERT 查询前一行？
最佳答案
来自 MySQL 手册:
The ID that was generated is maintained in the server on a per-connection basis. This means that the value returned by the function to a given client is the first AUTO_INCREMENT value generated for most recent statement affecting an AUTO_INCREMENT column by that client. This value cannot be affected by other clients, even if they generate AUTO_INCREMENT values of their own. This behavior ensures that each client can retrieve its own ID without concern for the activity of other clients, and without the need for locks or transactions.
