Azure SQL - 通過多個數據庫查詢創建視圖

Question

我有兩個不同的數據庫，我需要來自兩個數據庫的信息。我設法得到這樣的數據：

create master key encryption by password = 'test' 

create database scoped crendetial testcredentials with identity = 'secret@login', secret = 'secret@password' 

-- CREATE DATA SOURCE -- 
create external data source RemoteDataSource with 
(
    type = RDBMS, 
    location = 'secret.database.windows.net', 
    database_name = 'testDB_Dev', 
    credential = testcredentials 
) 

-- CREATE TABLES -- 
create external table [RemoteDepartment] 
(
    [ID] [int], 
    [Name] [nvarchar](50) 
) 
with 
(
    data_source = RemoteDataSource, 
    schema_name = 'dbo', 
    object_name = 'Department' 
); 

在這裏，我現在可以select，join，等等。 （Employee表來自其他數據庫（一個我查詢））

select e.Name, e.Role, d.Name from Employee as e inner join 
    RemoteDepartment as d on d.ID = e.DepartmentId 

利用隨後的輸出

|---Name---|---Role---|---Name--| 
| Louise | Manager | HR | 
| Tim | Finances | Admin | 

這裏是我的問題。儘管這一切都非常好，而且速度很快，但我似乎無法將自己的頭腦包圍起來，或者在線查找任何資源，也無法瞭解如何使用這種查詢兩個獨立數據庫的方法創建視圖。

我曾嘗試以下：

create master key encryption by password = 'test' 

create database scoped crendetial testcredentials with identity = 'secret@login', secret = 'secret@password' 

-- CREATE DATA SOURCE -- 
create external data source RemoteDataSource with 
(
    type = RDBMS, 
    location = 'secret.database.windows.net', 
    database_name = 'testDB_Dev', 
    credential = testcredentials 
) 

-- CREATE TABLES -- 
create external table [RemoteDepartment] 
(
    [ID] [int], 
    [Name] [nvarchar](50) 
) 
with 
(
    data_source = RemoteDataSource, 
    schema_name = 'dbo', 
    object_name = 'Department' 
); 

CREATE VIEW test_view AS 
    select e.Name, e.Role, d.Name from RemoteEmployee as e inner join 
     RemoteDepartment as d on d.ID = e.DepartmentId 

但得到一個編譯錯誤說

語法錯誤： 'CREATE VIEW' 必須在該批次中唯一的語句

我試圖刪除除了select聲明以外的所有內容，但這不起作用（編譯器不知道什麼RemoteDepartment實際上是）

這聽起來像是一個簡單的情況，不能用Azure SQL數據庫實例進行跨數據庫查詢。
