sql server高效分页控件及c#调用实例

第一、首先在sqlserver中创建一个存储过程

USE [BZY]

GO

/****** 对象:  StoredProcedure [dbo].[up_ProcCustomPage2005_New]    脚本日期: 12/24/2013 11:17:03 ******/

SET ANSI_NULLS ON

GO

SET QUOTED_IDENTIFIER ON

GO



-- =============================================

-- Author:        <Author,,Name>

-- Create date: <Create Date,,>

-- Description:    <Description,,>

-- =============================================

CREATE PROCEDURE [dbo].[up_ProcCustomPage2005_New]

@SelectSql varchar(4000)

,@OrderBy varchar(4000)

,@PageSize int

,@PageIndex int

,@PageCount int output

,@RecordCount int output

AS



--SET @SelectSql = 'select * from table_3'

--SET @OrderBy = 'order by id desc'



Declare @sql nvarchar(4000)

SET @sql = 'select @RecourdCount = count(*) from (' + @SelectSql + ') as tt@#$'

EXEC sp_executesql @sql,N'@RecourdCount int OUTPUT',@RecordCount OUTPUT



SET @PageCount = CEILING( (@RecordCount + 0.0) / @PageSize)



IF @PageIndex > @PageCount

    SET @PageIndex = @PageCount

    

IF @PageIndex < 1

    SET @PageIndex = 1



DECLARE @StartIndex int

DECLARE @EndIndex int



SET @StartIndex = (@PageIndex-1) * @PageSize + 1

SET @EndIndex = @PageIndex * @PageSize

    

SET @sql = 'select * from (select row_number()over(' + @OrderBy + ') as rownumber,*  from (' + @SelectSql + ') AS tt@#$) as tt@#$result where rownumber between ' + cast(@StartIndex AS varchar) + ' and ' + cast(@EndIndex AS varchar) 

PRINT @sql    

EXEC sp_executesql @sql

二、c#代码：

        private static DataTable GetExecuteCustomPage_New(string selectSql, string orderBy, int pageSize, int pageIndex, out int pageCount, out int recordCount) 

        {

            MatchCollection mc = Regex.Matches(orderBy, @"([^ ]*)\.[^ ]*");



            if (mc.Count > 0)

            {

                foreach (Match item in mc)

                {                    

                    orderBy = orderBy.Replace(item.Groups[1].Value + ".", "");

                }

            }           



            SqlParameter SelectSql = new SqlParameter() { ParameterName = "@SelectSql", Size = 4000, Value = selectSql };

            SqlParameter OrderBy = new SqlParameter() { ParameterName = "@OrderBy", Size = 4000, Value = orderBy };

            SqlParameter PageSize = new SqlParameter() { ParameterName = "@PageSize", Size = 4, Value = pageSize , DbType = DbType.Int32 };

            SqlParameter PageIndex = new SqlParameter() { ParameterName = "@PageIndex", Size = 4, Value = pageIndex , DbType = DbType.Int32 };

            SqlParameter PageCount = new SqlParameter() { ParameterName = "@PageCount", Size = 4, Direction = ParameterDirection.Output , DbType = DbType.Int32 };

            SqlParameter RecordCount = new SqlParameter() { ParameterName = "@RecordCount", Size = 4, Direction = ParameterDirection.Output , DbType = DbType.Int32 };



            DataSet ds = new DataSet();

        

            using (SqlConnection cnn = new SqlConnection(ConfigurationManager.ConnectionStrings["DBConfig"].ToString())) 

            {

                SqlCommand cmd = cnn.CreateCommand();

                cmd.CommandText = "up_ProcCustomPage2005_New";

                cmd.CommandType = CommandType.StoredProcedure;

                cmd.Connection = cnn;

                cmd.Parameters.Add(SelectSql);

                cmd.Parameters.Add(OrderBy);

                cmd.Parameters.Add(PageSize);

                cmd.Parameters.Add(PageIndex);

                cmd.Parameters.Add(PageCount);

                cmd.Parameters.Add(RecordCount);

                SqlDataAdapter sda = new SqlDataAdapter(cmd);

                cnn.Open();

                sda.Fill(ds);



                pageCount = Convert.ToInt32(PageCount.Value);

                recordCount = Convert.ToInt32(RecordCount.Value);

            }



            return ds.Tables[0];



        }

三、引用例子

public DataSet GetPurchaserSalesVolumeAnalysis(string where,

           string sFilter_Condition, int iPage_Size, int iPage_Index, string sTaxisField,

           int iTaxis_Sign, out int iPageCount, out int iiRecord_Count)

        {



            string sql = @"select NewT.ptPaymentDate,NewT.fsStatus from Student NewT ";string orderwhere = " ORDER BY NewT.ptPaymentDate ";

            return BaitourDAO.Common.DBHelper.GetExecuteCustomPage_New(

                                  sql

                                  , orderwhere

                                  , iPage_Size

                                  , iPage_Index

                                  , out iPageCount

                                  , out iiRecord_Count);

        }
