关于where like

$s="%".addcslashes($uid, '%_')."%";return DB::fetch_all('select * from %t where uid like %s limit %d,%d',array($this->_table,$s,$start,$perpage));

上面的一段代码 可以查询出 关于UID是某位数字的用户全部信息

请问下 在这段代码里加点什么 可以是调用出来的信息 按信息ID的从大到小“desc”排序？

回复讨论(解决方案)

$s="%".addcslashes($uid, '%_')."%";
return DB::fetch_all('select * from %t where uid like %s order by id desc limit %d,%d',array($this->_table,$s,$start,$perpage));

order by id desc

$s="%".addcslashes($uid, '%_')."%";
return DB::fetch_all('select * from %t where uid like %s order by id desc limit %d,%d',array($this->_table,$s,$start,$perpage));

你的回答是正确的。感谢。

我还想追问下 在这段代码里 怎么添加排除语法? 比如uid >1

$s="%".addcslashes($uid, '%_')."%";
return DB::fetch_all('select * from %t where uid like %s and uid>1 order by id desc limit %d,%d',array($this->_table,$s,$start,$perpage));

$s="%".addcslashes($uid, '%_')."%";
return DB::fetch_all('select * from %t where uid like %s and uid>1 order by id desc limit %d,%d',array($this->_table,$s,$start,$perpage));

最后个问题 还是关于这个的

怎么在这段代码里 添加多运算的排除语法?
比如 发布日期变量为 time 有效期变量为day 当前时间变量为STAMP
怎么排除time+86400*day > STAMP 把这个运算加入里面？

$s="%".addcslashes($uid, '%_')."%";
return DB::fetch_all('select * from %t where uid like %s and uid>1 and time+86400*day>STAMP order by id desc limit %d,%d',array($this->_table,$s,$start,$perpage));

$s="%".addcslashes($uid, '%_')."%";
return DB::fetch_all('select * from %t where uid like %s and uid>1 and time+86400*day>STAMP order by id desc limit %d,%d',array($this->_table,$s,$start,$perpage));

但是STAMP 是当前时间戳的时间 数据库中并未录入 不能成立啊。。
