「同じキーを持つ項目がすでに追加されています」データセットを設定しようとするとSSRSでエラーが発生する

Question

SSRS IDEでデータセットを設定しようとすると、スナップショットに表示されるエラーが発生します。

クエリはSQL Server Management Studioで完全に正常に機能しますが、どこで問題が発生したのでしょうか。

DBへの接続が確立されています。

私のクエリ（長すぎる）を確認したい場合は、非常によく確認しました。何も問題はありません：

Answer 1

スクリプトを少しフォーマットしたところ、選択しているのと同じ名前の列が2つあることに気付きました。最終的な名前を変更し、Management Studioでステートメントを実行するときにすべての列にniqueの名前が付いていることを確認してください。

とはいえ、名前が重複していることに気付いた2つの列はcustomerquoteproducts.istaxpaidとcustomershipping.istaxpaidです。

お役に立てば幸いです。

Answer 2

同じ問題を受け取ったとき、今日この投稿に出くわしました。私の問題はそれまでとは少し異なりました。

SPに一時テーブルとIfステートメントがありました。私のSPは次のようになりました：

DECLARE @myCheck as int
SET @myCheck = 0

SELECT @myCheck = CASE WHEN [checkfield] = 'xxx' then 1 else 0 end
  FROM  checktable
  WHERE ...


SELECT myfields.*
into #temptable
FROM mytable
WHERE ...


IF @myCheck = 1     --if ssrs does'nt want ot refresh your fields, remove hte if as it does not see past this...
    select *
    FROM #temptable
        LEFT JOIN tableA
            ON ...
ELSE
    select *
    FROM #temptable
        LEFT JOIN tableB
            ON ...

そのため、SSRSでフィールドを "更新"するために、Ifステートメントをコメント化し、フィールド名を含むクエリの1つを保持しました。後ですべてを元に戻すことを忘れてはなりませんでした...
