Asp Gridview结合模糊查询(全文索引)的分页

   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

   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
@fieldOnenvarchar(20), --要查询的字段 强规
@fieldTwonvarchar(20), --一般规
@Tablenvarchar(20), --要查询的表
@TempIDNamenvarchar(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
@numint, --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
@fieldOnenvarchar(20), --要查询的字段 强规
@fieldTwonvarchar(20), --一般规
@TempIDNamenvarchar(20),--要排序的ID
@Tablenvarchar(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:

   protected void LastPage_Command(object sender, CommandEventArgs e)
{
int Count = int.Parse(lblCount.Text);

   if (Command == "FirstPage")
{
QuerryContent(5, 0);
CurrentCount.Text = "1";

   if (int.Parse(CurrentCount.Text) == 1)
{
PrevePage.Enabled = false;
NextPage.Enabled = true;
LastPage.Enabled = true;
FirstPage.Enabled = false;
}
}
else if (Command == "PrevePage")
{
int CurrentCountP = (int.Parse(CurrentCount.Text) - 1) * 5;
int NumP = CurrentCountP - 5;
QuerryContent(CurrentCountP, NumP);

   CurrentCount.Text = (int.Parse(CurrentCount.Text) - 1).ToString();

   if (int.Parse(CurrentCount.Text) == 1)
{
PrevePage.Enabled = false;
FirstPage.Enabled = false;
LastPage.Enabled = true;
NextPage.Enabled = true;
}
else
{
PrevePage.Enabled = true;
NextPage.Enabled = true;
LastPage.Enabled = true;
FirstPage.Enabled = true;
}

   }
else if (Command == "NextPage")
{
int CurrentCountN = (int.Parse(CurrentCount.Text) + 1) * 5;
int NumN = CurrentCountN - 5;
QuerryContent(CurrentCountN, NumN);

   CurrentCount.Text = (int.Parse(CurrentCount.Text) + 1).ToString();
if (int.Parse(CurrentCount.Text) == int.Parse(CountPage.Text))
{
PrevePage.Enabled = true;
NextPage.Enabled = false;
LastPage.Enabled = false;
FirstPage.Enabled = true;
}
else
{
PrevePage.Enabled = true;
NextPage.Enabled = true;
LastPage.Enabled = true;
FirstPage.Enabled = true;
}
}
else if (Command == "LastPage")
{
CurrentCount.Text = CountPage.Text;
int CurrentCountL = int.Parse(CountPage.Text) * 5;
int Num = CurrentCountL - 5;
QuerryContent(CurrentCountL, Num);

   PrevePage.Enabled = true;
NextPage.Enabled = false;
LastPage.Enabled = false;
FirstPage.Enabled = true;
}
}

   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
