ビューからのSQL Serverのフィルタデータ

Question

私は現在、何百万ものレコードを取得しているビューを持っており、単一の特定のアカウント番号までフィルタリングしたいと考えています。私は現在、アカウント番号（使いやすさ）でフィルターを使って新しいカスタムビューを作成したいと考えています。

これは私がそれを行っている方法です：[口座番号] = '1000'

VIEW_NAME FROM

SELECT *これは私が期待まさに私に与えます。ただし、VIEW_NAME_1000という新しいビューを作成してもう1つの変更を加えたい場合は、既存の日付フィールドに基づいて月の列を作成したいと考えています。

私はこれを試してみました：私はT1を必要に応じて

CASE 
    WHEN(MONTH(T1.[TRX Date]) = 1) THEN "January " + CONVERT(VARCHAR(4), YEAR(T1.[TRX Date])) 
    WHEN(MONTH(T1.[TRX Date]) = 2) THEN "February " + CONVERT(VARCHAR(4), YEAR(T1.[TRX Date])) 
    WHEN(MONTH(T1.[TRX Date]) = 3) THEN "March " + CONVERT(VARCHAR(4), YEAR(T1.[TRX Date])) 
    WHEN(MONTH(T1.[TRX Date]) = 4) THEN "April " + CONVERT(VARCHAR(4), YEAR(T1.[TRX Date])) 
    WHEN(MONTH(T1.[TRX Date]) = 5) THEN "May " + CONVERT(VARCHAR(4), YEAR(T1.[TRX Date])) 
    WHEN(MONTH(T1.[TRX Date]) = 6) THEN "June " + CONVERT(VARCHAR(4), YEAR(T1.[TRX Date])) 
    WHEN(MONTH(T1.[TRX Date]) = 7) THEN "July " + CONVERT(VARCHAR(4), YEAR(T1.[TRX Date])) 
    WHEN(MONTH(T1.[TRX Date]) = 8) THEN "August " + CONVERT(VARCHAR(4), YEAR(T1.[TRX Date])) 
    WHEN(MONTH(T1.[TRX Date]) = 9) THEN "September " + CONVERT(VARCHAR(4), YEAR(T1.[TRX Date])) 
    WHEN(MONTH(T1.[TRX Date]) = 10) THEN "October " + CONVERT(VARCHAR(4), YEAR(T1.[TRX Date])) 
    WHEN(MONTH(T1.[TRX Date]) = 11) THEN "November " + CONVERT(VARCHAR(4), YEAR(T1.[TRX Date])) 
    WHEN(MONTH(T1.[TRX Date]) = 12) THEN "December " + CONVERT(VARCHAR(4), YEAR(T1.[TRX Date])) 
END as 'Trx Month' 

私は知りません。特に私が既に存在するビューからデータを取り出すだけなので、参照してください。

ここに私のSQLクエリ全体がありますが、期待どおりに動作していません...どこに私のケースを置いてもエラーメッセージが表示されます。

     WHEN(MONTH(T1.[TRX Date]) = 12) THEN "December " + CONVERT(VARCHAR(4), YEAR(T1.[TRX Date])) 
    END as 'Trx Month' 

GO 

どのようなステップがありますか？私は頭を悩ましており、どのように進行するか分からない。

Answer 1

あなたは大幅にコードを簡素化することができます：あなたは月の名前を生成するために、巨大なcase式を必要としない

CREATE VIEW [dbo].[VIEW_NAME_1000] AS 
    SELECT . . ., 
      DATENAME(MONTH, t.[TRX Date]) + ' ' + DATENAME(YEAR, t.[TRX Date]) 
    FROM dbo.AccountTransactions t 
    WHERE [Account Number] = '1000-000-00'; 

。
