首先看下面的代码创建存储过程

1、创建存储过程，语句如下：

 CREATE PROC P_viewPage @TableName VARCHAR(200), --表名 @FieldList VARCHAR(2000), --显示列名，如果是全部字段则为* @PrimaryKey VARCHAR(100), --单一主键或唯一值键 @Where VARCHAR(2000), --查询条件 不含'where'字符，如id>10 and len(userid)>9 @Order VARCHAR(1000), --排序 不含'order by'字符，如id asc,userid desc，必须指定asc或desc        --注意当@SortType=3时生效，记住一定要在最后加上主键，否则会让你比较郁闷 @SortType INT,   --排序规则 1:正序asc 2:倒序desc 3:多列排序方法 @RecorderCount INT,  --记录总数 0:会返回总记录 @PageSize INT,   --每页输出的记录数 @PageIndex INT,   --当前页数 @TotalCount INT OUTPUT,  --记返回总记录 @TotalPageCount INT OUTPUT  --返回总页数AS SET NOCOUNT ON IF ISNULL(@TotalCount,'') = '' SET @TotalCount = 0 SET @Order = RTRIM(LTRIM(@Order)) SET @PrimaryKey = RTRIM(LTRIM(@PrimaryKey)) SET @FieldList = REPLACE(RTRIM(LTRIM(@FieldList)),' ','') WHILE CHARINDEX(', ',@Order) > 0 OR CHARINDEX(' ,',@Order) > 0 BEGIN  SET @Order = REPLACE(@Order,', ',',')  SET @Order = REPLACE(@Order,' ,',',')  END IF ISNULL(@TableName,'') = '' OR ISNULL(@FieldList,'') = ''   OR ISNULL(@PrimaryKey,'') = ''  OR @SortType < 1 OR @SortType >3  OR @RecorderCount < 0 OR @PageSize < 0 OR @PageIndex < 0  BEGIN   PRINT('ERR_00')    RETURN END  IF @SortType = 3 BEGIN  IF (UPPER(RIGHT(@Order,4))!=' ASC' AND UPPER(RIGHT(@Order,5))!=' DESC')  BEGIN PRINT('ERR_02') RETURN END END DECLARE @new_where1 VARCHAR(1000) DECLARE @new_where2 VARCHAR(1000) DECLARE @new_order1

@new_order1 = ' ORDER BY ' + @PrimaryKey + ' DESC'    SET @new_order2 = ' ORDER BY ' + @PrimaryKey + ' ASC'   END  END ELSE  BEGIN   SET @new_order1 = ' ORDER BY ' + @Order  END IF @SortType = 3 AND CHARINDEX(','+@PrimaryKey+' ',','+@Order)>0  BEGIN   SET @new_order1 = ' ORDER BY ' + @Order   SET @new_order2 = @Order + ','     SET @new_order2 = REPLACE(REPLACE(@new_order2,'ASC,','{ASC},'),'DESC,','{DESC},')     SET @new_order2 = REPLACE(REPLACE(@new_order2,'{ASC},','DESC,'),'{DESC},','ASC,')   SET @new_order2 = ' ORDER BY ' + SUBSTRING(@new_order2,1,LEN(@new_order2)-1)     IF @FieldList <> '*'    BEGIN       SET @new_order3 = REPLACE(REPLACE(@Order + ',','ASC,',','),'DESC,',',')          SET @FieldList = ',' + @FieldList        WHILE CHARINDEX(',',@new_order3)>0     BEGIN      IF CHARINDEX(SUBSTRING(','+@new_order3,1,CHARINDEX(',',@new_order3)),','+@FieldList+',')>0      BEGIN       SET @FieldList =        @FieldList +

SUBSTRING(@FieldList,2,LEN(@FieldList))       END    END SET @SqlCount = 'SELECT @TotalCount=COUNT(*),@TotalPageCount=CEILING((COUNT(*)+0.0)/'     + CAST(@PageSize AS VARCHAR)+') FROM ' + @TableName + @new_where1 IF @RecorderCount = 0  BEGIN    EXEC SP_EXECUTESQL @SqlCount,N'@TotalCount INT OUTPUT,@TotalPageCount INT OUTPUT',         @TotalCount OUTPUT,@TotalPageCount OUTPUT  END ELSE  BEGIN

STR(@PageSize) + ' '+ @FieldList + ' FROM '           + @TableName + @new_where2 + @PrimaryKey + ' < '           + '(SELECT MIN(' + @PrimaryKey + ') FROM (SELECT TOP '           + STR(@TotalCount-@PageSize*@PageIndex) + ' ' + @PrimaryKey+ ' FROM ' + @TableName           + @new_where1 + @new_order2 +' ) AS TMP) '+ @new_order2+ ' ) AS TMP ' + @new_order1      END    END   IF @SortType = 2 --仅主键反序排序    BEGIN     IF @PageIndex <= CEILING((@TotalCount+0.0)/@PageSize)/2 --正向检索      BEGIN       SET @Sql = 'SELECT TOP ' + STR(@PageSize) + ' ' + @FieldList + ' FROM '+ @TableName

@SortType = 3 --多列排序，必须包含主键，且放置最后，否则不处理    BEGIN     IF CHARINDEX(',' + @PrimaryKey + ' ',',' + @Order) = 0      BEGIN PRINT('ERR_02') RETURN END     IF @PageIndex <=

TMP ' + @new_order1      END    END  END PRINT(@Sql) EXEC(@Sql)GO

2、SQL Server 中调用测试代码

--执行存储过程declare @TotalCount int,    @TotalPageCount intexec P_viewPage 'T_Module','*','ModuleID','','',1,0,10,1,@TotalCount output,@TotalPageCount outputSelect @TotalCount,@TotalPageCount;

asp.net 代码实现：

#region ===========通用分页存储过程===========  public static DataSet RunProcedureDS(string connectionString, string storedProcName, IDataParameter[] parameters, string tableName)  { using (SqlConnection connection = new SqlConnection(connectionString)) {   DataSet dataSet = new DataSet();   connection.Open();   SqlDataAdapter sqlDA = new SqlDataAdapter();   sqlDA.SelectCommand = BuildQueryCommand(connection, storedProcName, parameters);   sqlDA.Fill(dataSet, tableName);   connection.Close();   return dataSet; }  }  /// <summary>  /// 通用分页存储过程  /// </summary>  /// <param name="connectionString"></param>  /// <param name="tblName"></param>  /// <param name="strGetFields"></param>  /// <param name="primaryKey"></param>  /// <param name="strWhere"></param>  /// <param name="strOrder"></param>  /// <param name="sortType"></param>  /// <param name="recordCount"></param>  /// <param name="PageSize"></param>  /// <param name="PageIndex"></param>  /// <param name="totalCount"></param>  /// <param name="totalPageCount"></param>  /// <returns></returns>  public static DataSet PageList(string connectionString, string tblName, string strGetFields, string primaryKey, string strWhere, string strOrder, int sortType, int recordCount, int PageSize, int PageIndex,ref int totalCount,ref int totalPageCount)  { SqlParameter[] parameters ={ new SqlParameter("@TableName ",SqlDbType.VarChar,200),  new SqlParameter("@FieldList",SqlDbType.VarChar,2000),  new SqlParameter("@PrimaryKey",SqlDbType.VarChar,100),  new SqlParameter("@Where",SqlDbType.VarChar,2000),  new SqlParameter("@Order",SqlDbType.VarChar,1000),  new SqlParameter("@SortType",SqlDbType.Int),  new SqlParameter("@RecorderCount",SqlDbType.Int),  new SqlParameter("@PageSize",SqlDbType.Int),  new SqlParameter("@PageIndex",SqlDbType.Int),  new SqlParameter("@TotalCount",SqlDbType.Int),  new SqlParameter("@TotalPageCount",SqlDbType.Int)}; parameters[0].Value = tblName; parameters[1].Value = strGetFields; parameters[2].Value = primaryKey; parameters[3].Value = strWhere; parameters[4].Value = strOrder; parameters[5].Value = sortType; parameters[6].Value = recordCount; parameters[7].Value = PageSize; parameters[8].Value = PageIndex; parameters[9].Value = totalCount; parameters[9].Direction = ParameterDirection.Output; parameters[10].Value = totalPageCount; parameters[10].Direction = ParameterDirection.Output; DataSet ds = RunProcedureDS(connectionString, "P_viewPage", parameters, "PageListTable"); totalCount = int.Parse(parameters[9].Value.ToString()); totalPageCount = int.Parse(parameters[10].Value.ToString()); return ds;  }  #endregionDataSet ds = SqlHelper.PageList(SqlHelper.LocalSqlServer, "T_User", "*", "UserID", "", "", 1, 0, pageSize, 1, ref totalCount, ref totalPageCount);this.RptData.DataSource = ds;this.RptData.DataBind();
