php框架 - php mysql limit 分页问题
我想问实际应用中都是使用limit n,m这样来实现分页吗?
但是我发现这样有一个问题,数据“错乱”问题,当数据变化频繁时,使用ajax来做瀑布流时会出现重复显示信息,或者有的直接被错过了,因为,因为,因为因为什么这个很容易想到吧,因为n,m发生了变化,数据的总和在短时间发生了变化,也就导致了limit在这里得到的数据库出现“错乱”
我不知道怎么解决这个问题,只能说用limit分页太菜了,实际中不可能这样做分页吧

2333瀑布流哪有这么分页的。。。
瀑布流的排序依据是什么?时间啊。上次读到哪,从哪开始读就行了。
比如上次读到 1点钟,那么下一页应该是:
<code>select * from tbl where datetime > 1点钟 limit 10</code>
这个你就别用limit offset嘛。你可以自己写select,比如你每次取第二页时把最后的id发过来,再用limit从id+1开始取n个就可以了嘛
