使用1个查询中的2个不同的sql数据库

Question

我需要修改以下sql 2014组查询以使用来自2个不同服务器的两个单独的数据库。

在计算过去7天的平均收入总额之前，我需要首先确定总收入，总成本，&两个数据库之间的总毛利。我使用的只是它的伟大作品当前功能不使用收入的总和从两个database.Tables [DBO]总计[dw_rpt_traffic] & [mediaalpha] [PublisherCallByDay]

我需要加入从表2个不同的server.databases。注意他们应该加入CallDate & CreateDate。但是这两个表都不包含过去90天所需的所有日期（基于当前日期运行90天），因此这将影响所需的连接类型。

修改后的代码：仍然有代码的最后部分的问题，以合并来自两个数据源的数据以确定平均值。错误：无效的对象名称'rpt'。

WITH RPT 
     AS (SELECT x.CreateDate 
        , x.RevenueTotals 
        , (x.RevenueTotals-x.COSTTOTALS) as GrossProfit

          , SUM([AGENT_REV]+[ANCHOR_REV]+[CORP_REV]+[OFFSITE_REV]) as RevenueTotals

         WHERE  CAST(t.CREATE_DTG AS DATE) > CAST(GETDATE() - 90 AS DATE)

Answer 1

我认为解决这个最好的方法是在服务器添加链接的服务器，所以你可以调用其他数据库。

对于这一点，你去一台服务器，并在出现的根目录中的文件夹中，有一个“服务器对象”文件夹，一旦进入，展开链接服务器的文件夹。您可以通过右键单击该文件夹并选择“新链接服务器”选项来添加新的链接服务器。

您必须完成这些信息，例如它是SQL Server实例或其他信息。

最后，在安全选项卡，必须输入凭据（用户名和密码登录服务器），喜欢它的下一个图像中的真实所示：

一旦你准备好这一点，您可以通过右键单击来测试新的链接服务器，然后选择“测试连接”。

如果它工作正常，则只需指定服务器和表，这样调用该数据库的任何表：

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

在你的情况，应该是这样

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]
