--Step 1  创建表变量 
--所有分页筛选后的POSTID
declare @ZModulePosts_AllInfo_Temp Table

PostID  varchar(10),
ModuleID varchar(10) ,

--Step 2 分页输出
--定义第一行记录
declare @firstRow int;
--定义最后一条记录
declare @lastRow int;--设置第一条记录
set @firstRow=((@Page-1)*@PageSize)+1;
--设置最后一条记录
set @lastRow=@firstRow+@PageSize;--定义查询SQL字段
 
insert into @ZModulePosts_AllInfo_Temp
select * from

where ForumPostID.ModuleID=@ModuleID
) as TB 
where  TB.RowNumber>=@firstRow and TB.RowNumber<@lastRow  

----------------分页输出完毕--------

--Step 3 联表输出
 select ForumPosts.PostID,ForumPosts.Title,ForumPosts.ModuleID,ForumModules.[Name] , ForumPosts.UserName,ForumPosts.PubTime,ForumPosts.LastReplier,ForumPosts.LastReplyTime,ForumPosts.IsDelete,ForumPosts.IsLock  
from  ForumPosts ,ForumModules ,@ZModulePosts_AllInfo_Temp as ZMAT
where  
  ZMAT.PostID=ForumPosts.PostID
and ForumModules.ModuleID = @ModuleID
and ForumPosts.IsDelete=0 --筛选已删除的
Order by PostID desc
  


 

数据库表冗余存储+PostID表+分页
