怎么删除MYSQL中的一条数据不指定id的数据


回复讨论(解决方案)

不指定id总有其他条件吧,不然怎么知道要删哪个呢

那总还有其他识别标志吧


想实现点击删除,然后删除数据库内对应的id信息

不指定id总有其他条件吧,不然怎么知道要删哪个呢

删除一条数据首先要知道是哪条,知道是哪条就是用这条数据的字段数据来区分的,类似ID,NAME,TIME等等,不指定ID那就得指定其他的字段,如果字段数据不唯一会把同样的都删掉。

点击“删除”时把 id 带过去


想实现点击删除,然后删除数据库内对应的id信息
总要有一个条件吧,要不怎么知道你要删除哪一条呢,这种删除一般都是把表中唯一标识传过去。这的这张图片上可以不显示这个唯一的标识,但你要读取出来隐藏,以作为找到这条数据的依据,就像你的身份证号一样。

你好,你这个是通过 获取ID 删除的。。
