随机抽取3条连续的记录?如表: temID 1 2 3 4 5 6 7 8 如果取3条记录,结果可以是: 1 2 3 或 4 5 6 或 7 8 1 或 8 1 2 等等 想不出mysql如何写?请问 用php 取出来后有无好的办法 ,进行随机抽取 随机抽取?php?mysql ------解决方案--------------------用rand(1,8)获取随机整数,存放在一个长度为3的列表里,如果获取到的随机整数与之前的一样,重新获取,取到3个不同的数以后,以这3个数为ID到数据库里去取记录------解决方案-------------------- 引用: 781和812还算连续数据嘛?你这成环形链表了。 select * from test as t1 join (select round(rand() * (select max(temID) from `test`)) as id) as t2 where t1. temID >= t2. temID order by t1. temID asc limi…… 上面有笔误 select * from test as t1 join (select round(rand() * (select max(temID) from `test`)) as temID) as t2 where t1.temID >= t2.temID order by t1.temID asc limit 3;
