 到网上搜分页存储过程一大把。但是有些需求的话,对于一般的存储过程不适用。经过一天多的摸索。终于写出了属于自己的分页存储过程(里面包含全文索引的查询哦) 希望对大家有一点点帮助!

    效果如图   

Asp Gridview结合模糊查询(全文索引)的分页

    本人开发的环境是c#2008+sqlserver2008,将要查询的字段填充好全文索引后。便可以展开工作了。

    用三层模式开发、  专门新建了一个Querry类,在接口层定义好方法:

   

        /// <summary>
        /// 安全规范的分页查询
        /// </summary>
        /// <param name="q">所需参数</param>
        /// <returns>返回一个SStand的集合</returns>
        IList<SStand> GetAllBySStand(QuerryContent q);

        /// <summary>
        /// 得到查询单总数
        /// </summary>
        /// <param name="q"></param>
        /// <returns></returns>
        int GetCount(QuerryContent q);

    因为查询的页面有很多。并且查询的表也不相同,所以把分页存储过程做成了通用的(废话了)进入主题: 存储过程

  第一次查询一个新的东西的时候,先得到这个查询集合的总数(这也是本存储过程不足的)

 CreateProcedure Popular_PageListCount
 @ContentOne   nvarchar(20),  --查询关键字
 @ContentTwo   nvarchar(20),
 @ContentThree  nvarchar(20),
 @TempTypeID  int,         --所属分类
 @TempTypeIDName  nvarchar(50),  --所属分类名 与上对应  两个是一起的
 @fieldOne nvarchar(20),   --要查询的字段  强规
 @fieldTwo nvarchar(20),        --一般规
 @Table nvarchar(20),  --要查询的表
 @TempIDName nvarchar(20)   --要排序的ID
 AS
 declare @sql  nvarchar(300)
 declare @opreat nvarchar(20)
if @ContentTwo is null or @ContentTwo=''
set @opreat='or'
else
set @opreat='and'
 set @sql='select count(*) from '+@Table+'
inner join
containstable('+@Table+',(['+@fieldOne+'],['+@fieldTwo+']),''("'+@ContentOne+'" '+@opreat+' "'+@ContentTwo+'" or "'+@ContentThree+'")'',50) as k
on '+@TempIDName+'=k.[key]
where '+@TempTypeIDName+'='+CONVERT(nvarchar,@TempTypeID)+''
exec sp_executeSQL @sql

 

  正式分页存储过程

 Create Procedure Popular_PageList
@ContentOne   nvarchar(20),   --查询关键字
@ContentTwo   nvarchar(20),
@ContentThree  nvarchar(20),
@CurrentCount   int,   ----当前的索引,假设每页5条数据,第二页的话,currencount为10
@num   int,   --每页的条数
@TempTypeID  int,          --所属分类
@TempTypeIDName  nvarchar(50),  --所属分类名 与上对应  两个是一起的
@fieldOne nvarchar(20),   --要查询的字段  强规
@fieldTwo nvarchar(20),        --一般规
@TempIDName nvarchar(20),   --要排序的ID
@Table nvarchar(20)  --要查询的表
AS
declare @Sql   nvarchar(300)
declare @opreat nvarchar(20)
if @ContentTwo is null or @ContentTwo=''
set @opreat='or'
else
set @opreat='and'
set @Sql='with cte as(select top '+CONVERT(nvarchar,@CurrentCount)+' *,row_number() over(order by  '+@TempIDName+' asc) as num from '+@Table+'
 inner join containstable('+@Table+',(['+@fieldOne+'],['+@fieldTwo+']),''("'+@ContentOne+'") '+@opreat+' ("'+@ContentTwo+'")or("'+@ContentThree+'")'',50) as k
 on '+@TempIDName+'=k.[key]
 where '+@TempTypeIDName+'='+CONVERT(nvarchar,@TempTypeID)+'
 order by '+@TempIDName+' asc)
select * from cte where num>'+CONVERT(nvarchar,@num)+''
exec sp_executeSQL  @sql

  页面后台

   定义一个查询方法:

 private void QuerryContent(int CurrentCount, int Num)
        {
            BQuerryContent b = new BQuerryContent();
            QuerryContent q1 = new QuerryContent();
            IList<SStand> item = new List<SStand>();

            q1.ContentTwo = txtContentTwo.Text;
            q1.ContentThree = txtContentThree.Text;
            q1.CurrentCount = CurrentCount;
            q1.Num = Num;
            q1.TempTypeID = int.Parse(ddlSStand.SelectedValue);
            q1.TempTypeIDName = "SStandTypeID";
            q1.FieldOne = "SStandFRContent";  //要匹配的字段
            q1.FieldTwo = "SStandGRContent";
            q1.Table = "SStand";   //表名
            q1.TempIDName = "SStandID";
            item = b.GetAllBySStand(q1);
            gdvContent.DataSource = GridViewSet(item);
            gdvContent.DataBind();
        }

 

   调用:

   因本人是菜鸟,所以里面定义的一些东西不够规范,在存储分页上还有不足,要先得到它的总数,意思就是要连接数据库2次。 这个地方可以改进! 望高人看到,可以给一点指点。 在此特别鸣谢,爱瞎想的猪,和不是NB的人给了我在存储过程上的一点指示
