使用sql存储过程实现分页,在网上能找到好多种解决方案,但是如何用asp.net后台调用呢,通过本篇文章小编给大家详解asp.net中如何调用sql存储过程实现分页,有需要的朋友可以来参考下
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 VARCHAR(1000)
- DECLARE @new_order2 VARCHAR(1000)
- DECLARE @new_order3 VARCHAR(1000)
- DECLARE @Sql VARCHAR(8000)
- DECLARE @SqlCount NVARCHAR(4000)
- IF ISNULL(@where,'') = ''
- BEGIN
- SET @new_where1 = ' '
- SET @new_where2 = ' WHERE '
- END
- ELSE
- BEGIN
- SET @new_where1 = ' WHERE ' + @where
- SET @new_where2 = ' WHERE ' + @where + ' AND '
- END
- IF ISNULL(@order,'') = '' OR @SortType = 1 OR @SortType = 2
- BEGIN
- IF @SortType = 1
- BEGIN
- SET @new_order1 = ' ORDER BY ' + @PrimaryKey + ' ASC'
- SET @new_order2 = ' ORDER BY ' + @PrimaryKey + ' DESC'
- END
- IF @SortType = 2
- BEGIN
- SET @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(@new_order3,1,CHARINDEX(',',@new_order3))
- END
- SET @new_order3 =
- SUBSTRING(@new_order3,CHARINDEX(',',@new_order3)+1,LEN(@new_order3))
- END
- SET @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
- SELECT @TotalCount = @RecorderCount
- END
- IF @PageIndex > CEILING((@TotalCount+0.0)/@PageSize)
- BEGIN
- SET @PageIndex = CEILING((@TotalCount+0.0)/@PageSize)
- END
- IF @PageIndex = 1 OR @PageIndex >= CEILING((@TotalCount+0.0)/@PageSize)
- BEGIN
- IF @PageIndex = 1 --返回第一页数据
- BEGIN
- SET @Sql = 'SELECT TOP ' + STR(@PageSize) + ' ' + @FieldList + ' FROM '
- + @TableName + @new_where1 + @new_order1
- END
- IF @PageIndex >= CEILING((@TotalCount+0.0)/@PageSize) --返回最后一页数据

- + ' ' + @FieldList + ' FROM '
- + @TableName + @new_where1 + @new_order2 + ' ) AS TMP '
- + @new_order1
- END
- END
- ELSE
- BEGIN
- IF @SortType = 1 --仅主键正序排序
- BEGIN
- IF @PageIndex <= CEILING((@TotalCount+0.0)/@PageSize)/2 --正向检索
- BEGIN
- SET @Sql = 'SELECT TOP ' + STR(@PageSize) + ' ' + @FieldList + ' FROM '
- + @TableName + @new_where2 + @PrimaryKey + ' > '
- + '(SELECT MAX(' + @PrimaryKey + ') FROM (SELECT TOP '
- + STR(@PageSize*(@PageIndex-1)) + ' ' + @PrimaryKey
- + ' FROM ' + @TableName
- + @new_where1 + @new_order1 +' ) AS TMP) '+ @new_order1
- END
- ELSE --反向检索
- BEGIN
- SET @Sql = 'SELECT TOP ' + STR(@PageSize) + ' ' + @FieldList + ' FROM ('
- + 'SELECT TOP ' + 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 '

- + '(SELECT MIN(' + @PrimaryKey + ') FROM (SELECT TOP '
- + STR(@PageSize*(@PageIndex-1)) + ' ' + @PrimaryKey
- +' FROM '+ @TableName
- + @new_where1 + @new_order1 + ') AS TMP) '+ @new_order1
- END
- ELSE --反向检索
- BEGIN

- END
- END

- + @new_order1 + ' ) AS 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 int
- exec P_viewPage 'T_Module','*','ModuleID','','',1,0,10,1,@TotalCount output,@TotalPageCount output
- Select @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;
- }
- }

- return ds;
- }
- #endregion
- DataSet ds = SqlHelper.PageList(SqlHelper.LocalSqlServer, "T_User", "*", "UserID", "", "", 1, 0, pageSize, 1, ref totalCount, ref totalPageCount);
- this.RptData.DataSource = ds;
- this.RptData.DataBind();
