查询新闻类别下的每个分类的第二条信息列表的存储过程

---存储过程（查询每个类别的所有分类第二条数据的前n条不在前num条的信息）
create procedure proc_selectNewsClassTwoInfo
@ParentID int, //新闻父Id
@Num1 int=0, //查询的前几条
@Num2 int=0 //不在几条的，比如：查询5-9条，则参数为4

----执行存储过程 ,传入3个参数，一个父id，一个是前几条，一个是不在前几条的

exec proc_selectNewsClassTwoInfo @ParentID=14,@Num1=10,@Num2=0
