比如我想取portal_category这个表中所有字段的值
C::t('portal_category')->fetch........................ 后面怎么写呢?


回复讨论(解决方案)

C::t('portal_category')->fetch($id);//$id是主键
你可以到/source/class/table/目录下查看所有封装的表模型
你也可以用DB类操作数据库（表模型底层都是用的DB类操作的）
$res=DB::fetch_first('select * from %t where catid=%d',array('portal_category',1));
