在高流量应用程序中,mysqli_insert_id()
是否有可能返回错误的 id,或者在几乎同时执行的两个 INSERT
查询之间混淆 id?
In a high traffic application, is it possible for mysqli_insert_id()
to return the wrong id, or to confuse the id between two INSERT
queries performed nearly simultaneously?
没有.mysqli_insert_id
返回当前连接上最近 INSERT
查询中最多的 AUTO_INCREMENT
值.例如,它永远不会与其他连接混淆.
No. mysqli_insert_id
returns the most the AUTO_INCREMENT
value from the most recent INSERT
query on the current connection. It will never get confused with another connection, for example.
