asp.net 利用多表联合查询进行汇总统计

3张表相关联，按照各个地区用户统计每个栏目在某个时间段的上报数量和审核数量，表结构如下图所示：

实现的效果如下图所示：

本来打算使用行转列实现，但是由于各个用户在不同时间段，有的栏目没有上报数据，造成一定问题，经过半天尝试，不行后，考虑栏目基本固定，使用Repeater嵌套实现，源码如下：

附上一个半途而废的存储过程，使用了行转列：

create proc [dbo].[proc_TJ]
(
@sql_where NVARCHAR(MAX)
)
as
DECLARE @sql_str NVARCHAR(MAX)
DECLARE @sql_col NVARCHAR(MAX)
DECLARE @tableName SYSNAME --行转列表
DECLARE @groupColumn SYSNAME --分组字段
DECLARE @row2column SYSNAME --行变列的字段
DECLARE @row2columnValue SYSNAME --行变列值的字段
DECLARE @alias NVARCHAR(20)
set @alias= '地区\类别'
SET @tableName = 'v_NewsArticles'
SET @groupColumn = 'username'
SET @row2column = 'name'
SET @row2columnValue = 'articleid'
--SET @sql_where = 'WHERE  createddate between ''2015-06-01'' and ''2015-08-01'''--从行数据中获取可能存在的列
SET @sql_str = N'
SELECT @sql_col_out = ISNULL(@sql_col_out + '','','''') + QUOTENAME(['+@row2column+']) FROM ['+@tableName+'] '+@sql_where+' GROUP BY ['+@row2column+']'
--PRINT @sql_str
EXEC sp_executesql @sql_str,N'@sql_col_out NVARCHAR(MAX) OUTPUT',@sql_col_out=@sql_col OUTPUT
--PRINT @sql_colSET @sql_str = N'
SELECT pvt.['+@groupColumn+'] as [地区\类别],pvt.[本省动态],pvt.[国内动态],pvt.[通知公告],pvt.[政策法规],pvt.[要闻聚焦],pvt.[公共机构节能],pvt.[标准规范],pvt.[节能产品],pvt.[节能案例],pvt.[节能常识],pvt.[节能宣传],pvt.[新产品新技术] FROM (SELECT ['+@groupColumn+'],['+@row2column+'],['+@row2columnValue+'] FROM ['+@tableName+']'+@sql_where+') p PIVOT (count(['+@row2columnValue+']) FOR ['+@row2column+'] IN ( '+ @sql_col +') ) AS pvt
ORDER BY pvt.['+@groupColumn+']'
PRINT (@sql_str)
EXEC (@sql_str)

在不加where条件时正常，如果加条件，就存在问题，如下图所示：
