調査のデータをSQLServerデータベースに保存しており、Tableauを使用して分析しています。Tableausの癖の1つは、このリンクが示すように、特定の形式のデータが必要なことです。

Tableauデータスタイル

ユニオンを使用する彼らの方法は機能しますが、私のデータは100の質問に分散しており、そのうちのいくつかには10のオプションがあります。UNIONこれにより、編集がほぼ不可能になる巨大なSQLステートメントが作成されます。

私の計画は、変更する必要のある各質問と結合を実行してから、変更する必要のない他のデータと内部結合することでしたが、結合の結果、最初のselectステートメントフィールドのみが返されます。

これが参考のためのユニオンステートメントです

 select
    [Survey].[SurveyId] AS [SurveyId],
    [HumanCapital_Issues].[DisclosureResponsibility_Importance] AS  [importance],
    'Disclosure Responsibility' as [HCI_Importance]
FROM [Survey].[Survey] [Survey] 
INNER JOIN [Survey].[HumanCapital_Issues] [HumanCapital_Issues] ON ([survey].[SurveyId] = [HumanCapital_Issues].[SurveyId])

union

    'Developing skills' as [HCI_Importance]

ユニオンを実行してから別のselectステートメントと結合する「簡単な方法」はありますか？

最終的に問題を理解した場合は、ほとんどのデータを取得する単一のクエリと、特定のセクションをその場所に取得するユニオン クエリを結合する必要があります。うまくいけば、SurveyID は接続要素です。既存のクエリを派生テーブルとして使用します。

select *
  from
  (
     { union query here }
  ) q1
 inner join
  (
     { query with all the data here }
  ) q2
    on q1.SurveyID = q2.SurveyID
