各位前辈大家好,现在我做出一个拼车功能,出发时间是用picker选的,该如何使得时间到了选定时间时自动删除数据库该条信息。敢问各位前辈是否可以实现该功能。望各位前辈不吝赐教,晚辈在此感谢万分!

How to automatically delete the information in the database when the time is up. Can you realize this function. I hope you can give me your advice. Thank you very much!

不删除。业务中基本不应该有单条删除功能,保留每一条历史是个好习惯。
