g php的订单id<代码>自动提交是默认设置，即打开。我不执行手动提交，也不使用事务<代码>日期\u创建的字段是

DATETIME

类型。希望这能有所帮助。@VeeK-我又加了一些。切换到MariaDB，MySQL就输给Oracle了。我喜欢MariaDB的第一件事是它没有政治色彩。我喜欢MariaDB的第二件事是它默认在严格模式下运行。错误消息是您最好的朋友。我运行Hoo WinTail，对于错误，我让过滤器在我的MariaDB查询日志上运行

C:\cmdmp3win.exe“C:\ding_on.wav”

，这样我就可以知道程序在后台以其他方式安静运行时发生任何错误。我没有时间去钻研这个具体问题，我只是希望我的建议能有所帮助。祝你好运主键重复的可能性为零。该查询很好。请在您的答案中添加一些解释，以便其他人可以从中学习
