MarkedAsFinished
===========================================
id | partner_id | survey_id | version_id
-------------------------------------------
1 | 1 | 1 | 1
2 | 1 | 2 | 1
3 | 1 | 1 | 2
4 | 2 | 1 | 1
其中PK / FK关系从我的命名约定中不言自明。如果可能的话，我想要一个查询
CREATE PROCEDURE AnswerDump
@versid INT
AS
...
versid（对应Versions.id）等于1的情况下执行，则会返回以下表格。
name | Destined for Antarctica? | Destined for Coruscant? | Destined for Iraq? | Finished with Part 1? | Finished with Bonus? | Permission to contact about Part 1? | Permission to contact about Bonus? | What is 1+1? | What is 2+2? | How are you doing? | What would you rate her? | Number of bits in a byte? | What year is it?
=============================================================================================================================================================================================================================================================================================================================================
"John" | Yes | Yes | No | Yes | Yes | Yes | No | 2 | 4 | 55 | 9 | 8 | 2016
"Jacob" | No | Yes | No | Yes | No | Yes | No | 2 | 4 | 0 | 0 | 0 | 0
所以它基本上做的是将Partners用作行，将所有其他相关信息用作列。您可以看到，对于尚未填写的问题，它会填写零答案。
很抱歉，如果这看起来像是“为我编写代码”问题，但我确实付出了很多努力来编写它......
答案 0 :(得分：0)
是的，它可能，但在SQL视图中没有，您需要在SQL函数或SP中开发它们。
SQL数据透视的示例如下：
普通SQL：
USE AdventureWorks2008R2 ;
GO
SELECT DaysToManufacture, AVG(StandardCost) AS AverageCost
FROM Production.Product
GROUP BY DaysToManufacture;
透视SQL：
-- Pivot table with one row and five columns
SELECT 'AverageCost' AS Cost_Sorted_By_Production_Days,
[0], [1], [2], [3], [4]
FROM
(SELECT DaysToManufacture, StandardCost
FROM Production.Product) AS SourceTable
PIVOT
(
AVG(StandardCost)
FOR DaysToManufacture IN ([0], [1], [2], [3], [4])
) AS PivotTable;
