我试图创建一个外部表，该表引用同一sql server上运行的不同数据库引擎上的另一个表

这是我的疑问：

CREATE EXTERNAL TABLE [STG].[table]
(
    [id] [uniqueidentifier] NOT NULL
    
)
WITH (DATA_SOURCE = [topdesk],LOCATION = N'[topdesk].[dbo].[table]')
GO

我收到以下错误：

Msg 105082, Level 16, State 1, Line 10
105082;Generic ODBC error: [Microsoft][ODBC Driver 17 for SQL Server]Named Pipes Provider: Could not open a connection to SQL Server [53].

我不明白出了什么问题。我能够使用SSMS连接到数据库引擎。谢谢你的帮助
