サブクエリによる重複結果

Question

以下の長い質問に対しては、データベースの構成方法とSQLの知識が不足しているため、すばらしいプレイを得るための唯一の方法です。したがって、データベースにはMAX値が必要なフィールドTicketDateがあります。ただし、datetimeではなくchar（8）変数として定義されています。 MAXを入手するのはMAX(TicketDate as DATETIME)ほど簡単ではありませんが、実際には最大の日付にはなりません。

クエリが独自に動作します：

--***SUB QUERY (TimeTicketDet) 
     SELECT DISTINCT 
      cast(TicketDate as DATE) as MAXtt, 
      tt.JobNo 
     FROM TimeTicketDet as tt 

     ORDER BY 
      cast(TicketDate as DATE) DESC OFFSET 0 ROWS 

メインクエリに追加したときしかし、私は各TimeTicketEntryのために重複した行を取得します。最後のサブクエリ（重複なし）なしでクエリが正常に動作します--***SUB QUERY (TimeTicketDet)。 JobNoはTimeTicketDetテーブルの一意の識別子で、リンクとして使用されました。

DECLARE @now DATETIME 
DECLARE @90daysago DATETIME 

SET @now = GETDATE() 
SET @90daysago = DATEADD(day, -90, @now) 


SELECT 
    o.PartNo,

      WHEN tt.MAXtt >= po.DateEnt AND tt.MAXtt >= r.ReceiveDate THEN cast(tt.MAXtt as DATE) 
      ELSE po.DateEnt

クエリの目標は、すべての関連の日付を見つける< = 90日齢、リストに追加されます。私が見逃しているのは、最後の日付です。これは、正しいTicketDateをTimeTicketDetテーブルから取り出し、JobNoに参加させることになります。

リクエストした情報を追加したり削除したりできます。

Answer 1

はあなたにサブクエリを変更してみてください：

SELECT MAX(CAST(TicketDate as DATE)) as MaxTT, 
     JobNo 
FROM TimeTicketDet as tt 
GROUP BY JobNo 

私はあなたの現在のクエリが任意のJobNo
