动态 Sql Pivot 表的两列

Question

使用动态数据透视表，我正在尝试获取此表：http://www.sqlfiddle.com/#!18/9f1cf/47

看起来像这样：（为简洁起见删除了一些列，假设我可以有一个或多个列通过“Chosen Council”，这只是预期的设计而不是预期的结果）

请注意，邮政编码可以为空，可以共享委员会，并且可以在几天内重复

+============+=======+================+============================+====================================+=========================+=====================+
| Call Date  |  Zip  | Chosen Council | Early Childhood Group Care | Development / Developmental Delays | Caregiver Mental Health | Behavioral Concerns |

我看到了很多关于数据透视表的问题，包括硬编码的和动态的，但我仍然没有掌握它。

在这里，我能够获得仅包含呼叫主题名称及其计数的动态数据透视表：http://www.sqlfiddle.com/#!18/9f1cf/39
但这只是所有内容的单行，它似乎也忽略了空值。

在这里，我尝试扩展上述内容，虽然看起来间隔更好，但我还没有弄清楚如何附加我的通话日期、邮编或选定的委员会列：http://www.sqlfiddle.com/#!18/9f1cf/37

有什么想法可以做到这一点吗？

ASCII 表的制作：用https://ozh.github.io/ascii-tables/制作

也许你需要像下面这样的东西

DECLARE @columns NVARCHAR(MAX), @sql NVARCHAR(MAX);
SET @columns = N'';
SELECT @columns += N', _callTopics.' + QUOTENAME(Name)
  FROM
  (
    SELECT
      _callTopics.Name
    FROM CallTopics AS _callTopics
    INNER JOIN CallTopicsPerRegion AS _callTopicsPerRegion
        ON _callTopics.Name = _callTopicsPerRegion.CallTopicName
    GROUP BY _callTopics.Name
  ) AS x;
SET @sql = N'
  SELECT CallDate
  ,Zip
  ,ChosenCouncil, ' + STUFF(@columns, 1, 2, '') + '
  FROM
  (
    SELECT _callTopics.Name, _callTopicsPerRegion.CallTopicCount,
    CallDate
  ,Zip
  ,ChosenCouncil
    FROM CallTopics AS _callTopics
    INNER JOIN CallTopicsPerRegion AS _callTopicsPerRegion
    ON _callTopics.Name = _callTopicsPerRegion.CallTopicName
  ) AS j
  PIVOT
  (
    SUM(CallTopicCount) FOR Name IN ('
    + STUFF(REPLACE(@columns, ', _callTopics.[', ',['), 1, 1, '')
    + ')
  ) AS _callTopics order by 1,2 ,3';
--PRINT @sql;
EXEC sp_executesql @sql;
