Accessing Azure SQL Database tables from SAP HANA Cloud

In this blog we will explore how to access an Azure SQL Database table from SAP HANA Cloud.

Prerequisites

  1. You have access to Microsoft Azure portal
  2. An Azure SQL Database
  3. Access to Microsoft SQL Server Management Studio
  4. Access to SAP HANA Cloud instance
  5. DP Agent with MssqlLogReaderAdapter enabled

We will start with Azure side of things. So let’s login to the Microsoft Azure portal and navigate to the Azure SQL Database. Towards the right of overview, click on set server firewall

Set%20server%20firewall

Set server firewall

 

We need to add the following hosts into the firewall so that they can access the Azure SQL Database

  • Client Machine used to login to Azure portal
  • DP Agent Host
  • SQL Server Management Studio Host

Add%20IP%20to%20firewall

Add IP to firewall

 

Login to the host which has Microsoft SQL Management Studio and create a connection to the Azure SQL database. You can get the Server name from the overview section (screen shot 1)

Once connected to the Azure SQL Database, navigate to master database and run the below SQL

CREATE LOGIN DP_USER with password = 'Welcome01'
go

This SQL command will create a login for DP Agent to login to the Azure SQL database

Create%20login%20for%20DP%20Agent

Create login for DP Agent

 

Connect to user database SQLDB_HSC_DE and run the SQL to create a user for login DP_USER

Create user DP_USER for login DP_USER

Create%20user%20for%20login%20DP_USER

Create user for login DP_USER

 

Now, we will make the user DP_USER as the db owner using the following SQL command.

EXEC sp_addrolemember ‘db_owner’,’DP_USER’

Log on to Azure SQL Database as user DP_USER and enable Direct Administration Connection DAC using the following commands.

sp_configure ‘remote admin connections’, 1
go

reconfigure
go

sp_configure ‘remote admin connections’
go

 

Let us look at the table in Azure SQL Database that we want to access from SAP HANA Cloud. It is the Address table

Login to SAP HANA Cloud and open the database explorer . Then navigate to Remote Sources under Catalog

SAP%20HANA%20Cloud

Right click and add a new remote source named AZURE_SQL. We will need to provide the DP Agent location , Azure SQL Database IP and credentials to create the remote source as depicted in the below screenshot.

Once the remote source is created, it will display the objects in the Azure SQL database.

Choose the Address table and create a virtual object in SAP HANA Cloud.

Create%20virtual%20object%20in%20SAP%20HANA%20Cloud

Once the table is created, it will be visible under Tables in the SAP HANA Cloud catalog.

Conclusion

SAP HANA Cloud provides users with options to access data residing in cloud databases like Azure SQL Database quite easily with simple configuration steps. This allows users to see data from various different data sources in a single pane.
