Azure SQL Vertical Elastic Query tutorial error

Question

I am following the Microsoft tutorial for vertical elastic querying at https://docs.microsoft.com/en-us/azure/sql-database/sql-database-elastic-query-getting-started-vertical

I entered the code as follows:

CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'redacted'; 
CREATE DATABASE SCOPED CREDENTIAL ElasticDBQueryCred
WITH IDENTITY = 'redacted',
SECRET = 'redacted';

CREATE EXTERNAL DATA SOURCE MyElasticDBQueryDataSrc WITH
    (TYPE = RDBMS,
    LOCATION = 'redactedazure.database.windows.net',
    DATABASE_NAME = 'Redacted_Staging',
    CREDENTIAL = ElasticDBQueryCred,
    );

CREATE EXTERNAL TABLE [dbo].[CustomerInformation]
( [CustomerID] [int] NOT NULL,
  [CustomerName] [varchar](50) NOT NULL,
  [Company] [varchar](50) NOT NULL)
WITH
( DATA_SOURCE = MyElasticDBQueryDataSrc)

SELECT OrderInformation.CustomerID, OrderInformation.OrderId, CustomerInformation.CustomerName, CustomerInformation.Company
FROM OrderInformation
INNER JOIN CustomerInformation
ON CustomerInformation.CustomerID = OrderInformation.CustomerID;

However, I am getting the following errors:

Msg 46823, Level 16, State 1, Line 1 Error retrieving data from redactedazure.database.windows.net.Redacted_Staging. The underlying error message received was: 'Error retrieving data from redactedazure.database.windows.net.Redacted_Staging. The underlying error message received was: 'Error retrieving data from... (repeats)

Any idea why?

Answer 1

Did you ensure you possess ALTER ANY EXTERNAL DATA SOURCE permission?

ALTER ANY EXTERNAL DATA SOURCE permissions are needed to refer to the underlying data source.

Hope this can helps you.
