此文講述mvc4+entityframework6+sqlserver2008環境下呼叫儲存過程，實現分頁。

1、分頁儲存過程程式碼如下：

分頁原理用的row_number()和over()函式實現（沒有用top、not in，因為效能低；sqlserver2012有新特性，用offset、fetch實現）。

這裡支援多表查詢分頁。

SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO


CREATE PROCEDURE [dbo].[Procedure_SpiltPage
 
]
(    
    
    @pageIndex INT =1,                     --頁索引
    @pageSize INT =10,                     --頁大小
    @tableName NVARCHAR(100),              --表名    
    @fieldName NVARCHAR(200) ='*',         --查詢欄位
    @whereCondition NVARCHAR(800) ='1=1',  --where條件
    @orderCondition NVARCHAR(200),         --
 
order條件
    @recordTotal INT OUTPUT,               --輸出記錄總數
    @pageCount INT OUTPUT                  --輸出分頁數
)

AS
BEGIN
    DECLARE @sqlStr NVARCHAR(1000);
    
    SET NOCOUNT ON; --不返回計數
    
    --返回記錄總數
    SET @sqlStr = 'SELECT @recordTotal = COUNT(*) FROM '+@tableName+' WHERE '+@whereCondition
 

    EXEC sp_executesql @sqlStr,N'@recordTotal INT OUTPUT',@recordTotal OUTPUT
    SET @pageCount=(@recordTotal+@pageSize-1)/@pageSize
    
    --查詢列表    
    --如果是第一頁
    IF (@pageIndex<=1)
        BEGIN
            --N'表示強制轉換為Unicode字元,不會亂碼
            SET @sqlStr=N'SELECT TOP '+CAST(@pageSize AS VARCHAR)+' '+@fieldName+' FROM '+@tableName+' WHERE '+@whereCondition+' ORDER BY '+@orderCondition
        END
    ELSE
        BEGIN
            --為了適應多表查詢，下面把第一處@fieldName改為*，這裡不查詢全部欄位，因為第二個@fieldName
            SET @sqlStr=N'SELECT * FROM (SELECT ROW_NUMBER() OVER(ORDER BY '+@orderCondition+') AS rownum, '
                          +@fieldName+' FROM '+@tableName+' WHERE '+@whereCondition+') AS myTable WHERE rownum BETWEEN '
                          +CAST(((@pageIndex-1)*@pageSize+1) AS NVARCHAR)+' AND '+CAST((@pageIndex*@pageSize) AS NVARCHAR)
        END    
        
    EXEC (@sqlStr)
        
    SET NOCOUNT OFF;
END

GO

在資料庫中測試，可以如下：

declare @total int
declare @pageCount int
exec Procedure_SpiltPage 1,15,'NewsInfo','*','1=1','PostTime desc',@total output,@pageCount output
select @total as total,@pageCount as pageCounts

2、分頁實現程式碼：

 2.1、分頁資訊類如下：

namespace WebUI.PageinationService
{
    /// <summary>
    /// 分頁資訊類
    /// </summary>
    public class PageinationInfo
    {
        /// <summary>
        /// 頁索引
        /// </summary>            
        public int PageIndex { get; set; }
        /// <summary>
        /// 頁大小
        /// </summary>
        public int PageSize { get; set; }
        /// <summary>
        /// 總數
        /// </summary>
        public int TotalCount { get; set; }
        /// <summary>
        /// 總頁數
        /// </summary>
        public int TotalPages { get; set; }
        /// <summary>
        /// 表名
        /// </summary>
        public string TableName { get; set; }
        /// <summary>
        /// 主鍵
        /// </summary>
        public string KeyName { get; set; }
        /// <summary>
        /// 查詢欄位
        /// </summary>
        public string FieldName { get; set; }
        /// <summary>
        /// where條件（不帶'where'）
        /// </summary>
        public string WhereCondition { get; set; }
        /// <summary>
        /// 排序條件，如：id desc ，或者：id desc,name asc
        /// </summary>
        public string OrderCondition { get; set; }
    }
}

 2.2、分頁資料類（用以返回）

namespace WebUI.PageinationService
{
    /// <summary>
    /// 分頁資料類
    /// 用以將分頁集合和總數，總頁數等打包一起返回
    /// </summary>
    public class PageinationData
    {
        /// <summary>
        /// 總數
        /// </summary>
        public int TotalCount { get; set; }
        /// <summary>
        /// 總頁數
        /// </summary>
        public int TotalPages { get; set; }

        /// <summary>
        /// 集合
        /// </summary>
        public dynamic DataList { get; set; }
    }
}

 2.3、分頁實現類：

namespace WebUI.PageinationService
{
    /// <summary>
    /// 分頁讀取資料的實現類
    /// </summary>
    public class PageinationImplement
    {
        //資料庫上下文例項
        private MyDbContext db;

        public PageinationImplement(MyDbContext dbContext)
        {
            this.db = dbContext;
        }

        /// <summary>
        /// 讀取分頁資料
        /// </summary>
        /// <typeparam name="T">實體</typeparam>
        /// <param name="pageinationInfo">分頁資訊類</param>
        /// <returns>分頁資料</returns>
        public PageinationData GetPageinationData<T>(PageinationInfo pageinationInfo) where T : class
        {
            dynamic result = null;
            try
            {
                #region SqlParameter引數
                SqlParameter[] paras = new SqlParameter[8];
                //頁索引
                paras[0] = new SqlParameter("pageIndex", DbType.Int32);
                paras[0].Value = pageinationInfo.PageIndex;
                //頁大小
                paras[1] = new SqlParameter("pageSize", DbType.Int32);
                paras[1].Value = pageinationInfo.PageSize;                        
                //表名
                paras[2] = new SqlParameter("tableName", DbType.String);
                paras[2].Value = pageinationInfo.TableName;
                //查詢欄位
                //EF僅支援返回返回某個表的全部欄位，以便轉換成對應的實體，無法支援返回部分欄位的情況...？？？
                paras[3] = new SqlParameter("fieldName", DbType.String);
                paras[3].Value = pageinationInfo.FieldName;
                //where條件
                paras[4] = new SqlParameter("whereCondition", DbType.String);
                paras[4].Value = pageinationInfo.WhereCondition;
                //order條件
                paras[5] = new SqlParameter("orderCondition", DbType.String);
                paras[5].Value = pageinationInfo.OrderCondition;
                //總數
                paras[6] = new SqlParameter("totalCount", DbType.Int32);
                paras[6].Value = pageinationInfo.TotalCount;
                paras[6].Direction = ParameterDirection.Output;
                //總頁數
                paras[7] = new SqlParameter("totalPages", DbType.Int32);
                paras[7].Value = pageinationInfo.TotalPages;
                paras[7].Direction = ParameterDirection.Output;
                #endregion

                string sql = "Procedure_SpiltPage @pageIndex,@pageSize,@tableName,@fieldName,@whereCondition,@orderCondition,@totalCount output,@totalPages output";
                var list = db.Database.SqlQuery<T>(sql, paras).ToList();

                PageinationData data = new PageinationData();
                data.TotalCount= (int)paras[6].Value;
                data.TotalPages= (int)paras[7].Value;
                data.DataList = list;

                result = data;
            }
            catch(Exception e)
            {
                throw;
            }

            return result;
        }
    }
}

3、呼叫並返回資料： 

PageinationImplement pageImpl = new PageinationImplement(db);
PageinationInfo pageination = new PageinationInfo();
pageination.TableName = "NewsInfo";
pageination.PageIndex = 1;
pageination.PageSize = 15;
pageination.FieldName = "*";
pageination.OrderCondition = "PostTime desc";
pageination.WhereCondition = "Isdelete=0";                
var data = pageImpl.GetPageinationData<NewsInfo>(pageination);

上面的new PageinationImplement(db)中的db是資料庫上下文（DbContext例項），

上面的data裡包括了分頁列表，總記錄數，分頁頁數 資訊。
