Sql Server從一個表中選擇行，如果在日期範圍內沒有在另一個表中收集日期

我有兩個表一個是客戶團隊，另一個是CHeader，當我在客戶團隊中輸入記錄時，我應該在CHeader中收集數據（並在7天內提供專欄數據作爲'Ini Test'）。如果7天過去了，Cheader數據不是爲那個客戶收集的，那麼我應該可以在查詢輸出中獲得這些結果。注意：只有'Ini Test'類纔是這種情況下的有效數據。以下是查詢。Sql Server從一個表中選擇行，如果在日期範圍內沒有在另一個表中收集日期

  CREATE TABLE [dbo].[ClientTeam](
     [ClientTeamID] [int] IDENTITY(1,1) NOT NULL, 
     [TeamID] [int] NOT NULL, 
     [ClientID] [int] NOT NULL, 
     [Startdate] [smalldatetime] NOT NULL, 
     CONSTRAINT [PK15] PRIMARY KEY NONCLUSTERED 
     (
     [ClientTeamID] ASC 
     )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, FILLFACTOR = 80) ON [PRIMARY] 
     ) ON [PRIMARY] 

     GO

從我能理解，你要採取從ClientTeam數據，僅加入它的基礎上提到的標準來CHeader。

我會說從ClientTeam中選擇並左鍵連接到CHeader。您可以加入ON C.ClientID = CH.ClientID AND C.StartDate> DATEADD（DAY，-7，CH.CreateDate）AND CH.Kind ='Ini Test'

是的，但您的答案是不檢查clientTeam +7的開始日期是> currentdatetime。我應該能夠在鎖定開始日期的7天內得到客戶誰在臨牀標題中沒有數據的「Ini Test」 –

那麼你可以自己做，你的解釋不是很清楚。考慮在CreateDate上使用DATEADD函數並將其與GETDATE（）進行比較 – Ryan
