使用sql存儲過程實現分頁，在網上能找到好多種解決方案，但是如何用asp.net后臺調用呢，通過本篇文章小編給大家詳解asp.net中如何調用sql存儲過程實現分頁，有需要的朋友可以來參考下

首先看下面的代碼創建存儲過程

1、創建存儲過程，語句如下：

CREATE PROC P_viewPage

@TableName VARCHAR(200), --表名

@FieldList VARCHAR(2000), --顯示列名，如果是全部字段則為*

@PrimaryKey VARCHAR(100), --單一主鍵或唯一值鍵

@Where VARCHAR(2000), --查詢條件不含'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，必須指定asc或desc

--注意當@SortType=3時生效，記住一定要在最后加上主鍵，否則會讓你比較郁悶

@SortType INT, --排序規則 1:正序asc 2:倒序desc 3:多列排序方法

@RecorderCount INT, --記錄總數 0:會返回總記錄

@PageSize INT, --每頁輸出的記錄數

@PageIndex INT, --當前頁數

@TotalCount INT OUTPUT, --記返回總記錄

@TotalPageCount INT OUTPUT --返回總頁數

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

END

END

END

PRINT(@Sql)

EXEC(@Sql)

GO

2、SQL Server 中調用測試代碼

--執行存儲過程

declare @TotalCount int,

@TotalPageCount int

exec P_viewPage 'T_Module','*','ModuleID','','',1,0,10,1,@TotalCount output,@TotalPageCount output

Select @TotalCount,@TotalPageCount;

asp.net 代碼實現：

#region ===========通用分頁存儲過程===========

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;

}
