asp.net 利用多表聯合查詢進行彙總統計
3張表相關聯，按照各個地區使用者統計每個欄目在某個時間段的上報數量和稽核數量，表結構如下圖所示：
實現的效果如下圖所示：
本來打算使用行轉列實現，但是由於各個使用者在不同時間段，有的欄目沒有上報資料，造成一定問題，經過半天嘗試，不行後，考慮欄目基本固定，使用Repeater巢狀實現，原始碼如下：

DECLARE @row2column SYSNAME --行變列的欄位
DECLARE @row2columnValue SYSNAME --行變列值的欄位
DECLARE @alias NVARCHAR(20)
set @alias= '地區\類別'
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'''
--從行資料中獲取可能存在的列
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_col
SET @sql_str = N'
SELECT pvt.['+@groupColumn+'] as [地區\類別],pvt.[本省動態],pvt.[國內動態],pvt.[通知公告],pvt.[政策法規],pvt.[要聞聚焦],pvt.[公共機構節能],pvt.[標準規範],pvt.[節能產品],pvt.[節能案例],pvt.[節能常識],pvt.[節能宣傳],pvt.[新產品新技術] FROM (

PRINT (@sql_str)
EXEC (@sql_str)
在不加where條件時正常，如果加條件，就存在問題，如下圖所示：
