存储过程分页简单例子

       这段时间做个项目，数据量大的时候分页效果不是很少，用存储过程优化了一下，跟菜鸟们分享一下 共同进步。

存储过程：

set QUOTED_IDENTIFIER ON

ALTER  PROCEDURE [dbo].[ListPage](
@tblName     nvarchar(200),                 ----要显示的表或多个表的连接
@fldName     nvarchar(200) = '*',             ----要显示的字段列表
@pageSize    int = 10,                          ----每页显示的记录个数
@page        int = 1,                 ----要显示那一页的记录
@pageCount    int = 1 output,             ----]查询结果分页后的总页数
@Counts    int = 1 output,                 ----查询到的记录数

@Sort        bit = 0,                 ----排序方法，0为升序，1为降序
@strCondition    nvarchar(200) = null,    ----查询条件,不需where
@ID        nvarchar(50)        ----主表的主键
)
AS
SET NOCOUNT ON
Declare @sqlTmp nvarchar(1000)        ----存放动态生成的SQL语句
Declare @strTmp nvarchar(1000)        ----存放取得查询结果总数的查询语句

Declare @BeginID int            ----开始的ID
Declare @EndID   int            ----结束的ID



--------首先生成排序方法---------
if @Sort=0        --升序
begin
      if not(@fldSort is null)
        set @sqlSort = ' Order by ' + @fldSort
      else
        set @sqlSort = ' Order by ' + @ID
end
else            --降序
begin
    if not(@fldSort is null)
        set @sqlSort = ' Order by ' + @fldSort + ' DESC'
    else
        set @sqlSort = ' Order by ' + @ID + ' DESC '
end


--------生成查询语句--------
--此处@strTmp为取得查询结果数量的语句
if @strCondition is null    --没有设置显示条件
    begin
    set @sqlTmp =  @fldName + ' From ' + @tblName
    set @strTmp = 'select @Counts=Count(' + @ID + ') FROM '+@tblName
    set @strID = ' From ' + @tblName
    end
else
    begin
    set @sqlTmp = + @fldName + ' From ' + @tblName
    set @strTmp = 'select @Counts=Count(' + @ID + ') FROM '+@tblName + ' where ' + @strCondition
    set @strID = ' From ' + @tblName + ' where ' + @strCondition
    end



----取得查询结果总数量-----
exec sp_executesql @strTmp,N'@Counts int out ',@Counts out

--取得分页总数
if @Counts <= @pageSize
    set @pageCount = 1
else
    set @pageCount = (@Counts / @pageSize) + 1


--计算要移动的记录数
if @page = 1
    set @intCounts = @pageSize
else
begin
    set @intCounts = (@page-1) * @pageSize + 1
end

-----取得分页后此页的第一条记录的ID
set @strID = 'select @BeginID=' + @ID + ' ' + @strID



set @intCounts = @intCounts - @pageSize + 1
set rowcount  @intCounts
exec sp_executesql @strID,N'@BeginID int out ',@BeginID out

-----取得分页后此页的最后一条记录的ID
set @intCounts = @intCounts + @pageSize - 1
print @intCounts
set rowcount  @intCounts
exec sp_executesql @strID,N'@BeginID int out ',@EndID out


------恢复系统设置-----
set rowcount  0
SET NOCOUNT OFF

------返回查询结果-----
if @strCondition is null
    set @strTmp = 'select ' + @sqlTmp + ' where ' + @ID + ' between ' + str(@BeginID) + ' and ' + str(@EndID)
else
    set @strTmp = 'select ' + @sqlTmp + ' where ' + @ID +' between ' + str(@BeginID) + ' and ' + str(@EndID)  + ' and  ' + @strCondition

if not(@sqlSort is null)
set @strTmp = @strTmp + @sqlSort
exec sp_executesql @strTmp

页面后台实现：

DataTable dt = fwlog.Select(ldxx,zxbh,jtbz,clbz, kssj, jssj, page,orderPX,out count ,out totlepage);
           StringBuilder st = new StringBuilder();
           st.Append(" <table width='98%' align='center' border='1' align='center' cellpadding='3' cellspacing='0' style='border-collapse: collapse'  class='TableBorderStyle' >");
           st.Append("<tr class='TableTRBgStyle'>");

           st.AppendFormat("<td  align='center' >呼叫编号td>");
           st.AppendFormat("<td  align='center' >来电号码td>");
           st.AppendFormat("<td  align='center' >来电时间td>");
           st.AppendFormat("<td  align='center' >座席编号td>");
           st.AppendFormat("<td  align='center' >座席名称td>");
           st.AppendFormat("<td  align='center' >处理标志td>");
           st.AppendFormat("<td  align='center' >注销未接来电td>");
           st.AppendFormat("<td  align='center' >处理未接来电td>");


           st.Append("tr>");
           for (int i = 0; i < dt.Rows.Count; i++)
           {

               st.AppendFormat("<tr>");
               st.AppendFormat("<td width='40%' align='center' >{0}td>", dt.Rows[i]["HJBH"]);

               st.AppendFormat("<td width='40%' align='center' >{0}td>", dt.Rows[i]["ZXBH"]);
               if (dt.Rows[i]["ZXBH"].ToString() == "")

               }
               st.AppendFormat("<td width='40%' align='center' >{0}td>", tool.GetDMName("CLBZ", dt.Rows[i]["CLBZ"].ToString()));
               if (dt.Rows[i]["CLBZ"].ToString() == "0" || dt.Rows[i]["CLBZ"].ToString() == "2")
               {

                   st.AppendFormat("<td width='30%' align='center' ><img src='../../../p_w_picpaths/txt.gif' onclick='dd()' id='{0}'>td>", dt.Rows[i]["HJBH"]);
               }
               else
               {
                   st.AppendFormat("<td width='30%' align='center' ><img src='../../../p_w_picpaths/txt.gif' onclick='tt({0})' id='{0}'>td>", dt.Rows[i]["HJBH"]);
               }
               //st.AppendFormat("<td width='30%' align='center' ><img src='F:\\haiyan\\kfzx\\p_w_picpaths\\cc.ico' onclick='tt({0},{1})' id='{0}'>td>",dt.Rows[i]["HJBH"],dt.Rows[i]["CLBZ"]);
               st.AppendFormat("<td width='30%' align='center' ><img src='../../../p_w_picpaths/clbtn.gif'>td>");

               st.Append("tr>");
           }
           st.Append("<tr class='TableBottom'>");
           st.Append("  <td  colspan='8'><center>" + tool.GetPageCode(fwlog.Count(ldxx ,zxbh ,jtbz,clbz, kssj, jssj), page, 10, "", "") + "center>td>");
           st.Append("tr>");
           st.Append("table>");
           pagestr = st.ToString();

页面前台异步刷新：

//=========分页=====================
 function qq(dat)
            {
                q=dat;
                    $.get("ym_zxxt_ywsl_ldjl_selcet.aspx?z="+z,{cur:dat,LDXX:$("#LDXX").val()},function(data){
                    $("#select").html(data);
                    })
                    z++;
              }

比较简单的代码   没做什么过多的讲解 比较容易看懂
