mysql query quot sql

如何从数据库里面拿东西出来
数据库名:xl 表:page 字段有5个,ID-name-title-text-time

我连接数据库以后,怎么构造SQL语句查询ID大于0的表的,数据库里面ID是自动增加的。

sql="SELECT * FROM xl.page WHERE id>0"; //这样的不知道可不可以。

那应该怎么拿数据显示到页面来呢,我只是知道一个函数,但是不知道怎么用

$res = mysql_query($sql); //把拿到的数据赋值到 一个变量

然后呢 mysql_num_rows($res); //这样么,我这样试过了,显示不出来数据,如果要单独调用
字段里面的time 应该怎么做。谢谢
