asp.net中如何调用sql存储过程实现分页

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：

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,')
SET @new_order2 = ' ORDER BY ' + SUBSTRING(@new_order2,1,LEN(@new_order2)-1)
IF @FieldList <> '*'
BEGIN
SET @new_order3 = REPLACE(REPLACE(@Order + ',')
SET @FieldList = ',' + @FieldList
WHILE CHARINDEX(',@new_order3)>0
BEGIN
IF CHARINDEX(SUBSTRING(','+@new_order3,CHARINDEX(',@new_order3)),'+@FieldList+',')>0
BEGIN
SET @FieldList =
@FieldList + ',' + SUBSTRING(@new_order3,@new_order3))
END
SET @new_order3 =
SUBSTRING(@new_order3,@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
  BEGIN

• @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 '

  • 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 '
  • @TableName + @new_where2 + @PrimaryKey + ' < '
  • '(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
    SET @Sql = 'SELECT TOP ' + STR(@PageSize) + ' ' + @FieldList + ' FROM ('
  • 'SELECT TOP ' + STR(@PageSize) + ' '
  • @FieldList + ' FROM '
  • @TableName + @new_where2 + @PrimaryKey + ' > '

  • ' ) AS TMP ' + @new_order1
    END
    END
    IF @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

  • @new_order1 + ' ) AS TMP ' + @new_order1
    END
    END
    END
    PRINT(@sql)
    EXEC(@sql)
    GO

2、sql Server 中调用测试代码

rush:sql;"> --执行存储过程

declare @TotalCount int,@TotalPageCount int
exec P_viewPage 'T_Module','*','ModuleID','',10,@TotalCount output,@TotalPageCount output
Select @TotalCount,@TotalPageCount;

asp.net 代码实现：

rush:sql;"> #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; } } ///

/// 通用分页存储过程 ///

/// aram name="connectionString"> /// aram name="tblName"> /// aram name="strGetFields"> /// aram name="primaryKey"> /// aram name="strWhere"> /// aram name="strOrder"> /// aram name="sortType"> /// aram name="recordCount"> /// aram name="PageSize"> /// aram name="PageIndex"> /// aram name="totalCount"> /// aram name="totalPageCount"> /// 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",2000),new sqlParameter("@PrimaryKey",100),new sqlParameter("@Where",new sqlParameter("@Order",1000),new sqlParameter("@SortType",sqlDbType.Int),new sqlParameter("@RecorderCount",new sqlParameter("@PageSize",new sqlParameter("@PageIndex",new sqlParameter("@TotalCount",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;
}

endregion

DataSet ds = sqlHelper.Pagelist(sqlHelper.LocalsqlServer,"T_User","*","UserID","",pageSize,ref totalCount,ref totalPageCount);
this.RptData.DataSource = ds;
this.RptData.DataBind();
