问题描述
我用google_mysql_insert_id来查询线程安全问题... ...我担心我只有一个MySQL用户来连接数据库，因此，我认为mysql_insert_id对于我的应用程序不是很安全.是否有任何安全"的方法可以从MySQL返回最后一个插入ID?谢谢.
I google the mysql_insert_id, about the thread safe concern... ...I am worrying about I only have a one MySQL user to connect DB, so, I think mysql_insert_id is not very safe for my application. Is there any "safer" method for returning last insert id from MySQL? thank you.
推荐答案
只要没有两个线程共享一个数据库连接，就不应获取任何错误的ID. mysql_insert_id是按连接而不是按用户存储的.
As long as no two threads share one database connection you should not get any wrong ids. mysql_insert_id is stored per connection, not per user.
