使用1個查詢中的2個不同的sql數據庫

Question

我需要修改以下sql 2014組查詢以使用來自2個不同服務器的兩個單獨的數據庫。

在計算過去7天的平均收入總額之前，我需要首先確定總收入，總成本，&兩個數據庫之間的總毛利。我使用的只是它的偉大作品當前功能不使用收入的總和從兩個database.Tables [DBO]總計[dw_rpt_traffic] & [mediaalpha] [PublisherCallByDay]

我需要加入從表2個不同的server.databases。注意他們應該加入CallDate & CreateDate。但是這兩個表都不包含過去90天所需的所有日期（基於當前日期運行90天），因此這將影響所需的連接類型。

修改後的代碼：仍然有代碼的最後部分的問題，以合併來自兩個數據源的數據以確定平均值。錯誤：無效的對象名稱'rpt'。

Answer 1

我認爲解決這個最好的方法是在服務器添加鏈接的服務器，所以你可以調用其他數據庫。

對於這一點，你去一臺服務器，並在出現的根目錄中的文件夾中，有一個「服務器對象」文件夾，一旦進入，展開鏈接服務器的文件夾。您可以通過右鍵單擊該文件夾並選擇「新鏈接服務器」選項來添加新的鏈接服務器。

您必須完成這些信息，例如它是SQL Server實例或其他信息。

最後，在安全選項卡，必須輸入憑據（用戶名和密碼登錄服務器），喜歡它的下一個圖像中的真實所示：

一旦你準備好這一點，您可以通過右鍵單擊來測試新的鏈接服務器，然後選擇「測試連接」。

如果它工作正常，則只需指定服務器和表，這樣調用該數據庫的任何表：

SELECT Column1, Column2 FROM [ServerName].[DatabaseName].[Schema].[TableName] 

在你的情況，應該是這樣

SELECT CAST(t.Create_DTG AS DATE) AS CreateDate 
          , SUM([AGENT_REV]+[ANCHOR_REV]+[CORP_REV]+[OFFSITE_REV]) as RevenueTotals 
          , SUM([MEDIA_EST_COST]+[OTHER_COST]) as COSTTOTALS 
FROM [sqlclus3].[ABC342].[dbo].[dw_rpt_traffic]
