SAP HANA ODBC Driver

The SAP HANA ODBC Driver is a powerful tool that allows you to connect with SAP HANA, directly from any applications that support ODBC connectivity.

Access SAP HANA databases from virtually anywhere through a standard ODBC Driver interface.



Write a quick PowerShell script to query SAP HANA data. Use connectivity to the live data to replicate SAP HANA data to SQL Server.



The CData ODBC Driver for SAP HANA enables out-of-the-box integration with Microsoft's built-in support for ODBC. The ODBC driver instantly integrates connectivity to the real SAP HANA data with PowerShell.

You can use the .NET Framework Provider for ODBC built into PowerShell to quickly automate integration tasks like replicating SAP HANA data to other databases. This article shows how to replicate SAP HANA data to SQL Server in 5 lines of code.

You can also write PowerShell code to execute create, read, update, and delete (CRUD) operations. See the examples below.

Create an ODBC Data Source for SAP HANA

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Set the Server, Database and Port properties to specify the address of your SAP Hana database to interact with. Set the User and the Password properties to authenticate to the server.

Connect to SAP HANA

The code below shows how to use the DSN to initialize the connection to SAP HANA data in PowerShell:

$conn = New-Object System.Data.Odbc.OdbcConnection $conn.ConnectionString = "DSN=CData SAPHANA Source x64"

Back Up SAP HANA Data to SQL Server

After you enable caching, you can use the code below to replicate data to SQL Server.

Set the following connection properties to configure the caching database:

  • CacheProvider: The name of the ADO.NET provider. This can be found in the Machine.config for your version of .NET. For example, to configure SQL Server, enter System.Data.SqlClient.

  • CacheConnection: The connection string of properties required to connect to the database. Below is an example for SQL Server:

    Server=localhost;Database=RSB;User Id=sqltest;Password=sqltest;

The SQL query in the example can be used to refresh the entire cached table, including its schema. Any already existing cache is deleted.

$conn.Open() # Create and execute the SQL Query $SQL = "CACHE DROP EXISTING SELECT * FROM " + $Buckets $cmd = New-Object System.Data.Odbc.OdbcCommand($sql,$conn) $count = $cmd.ExecuteNonQuery() $conn.Close()

The driver gives you complete control over the caching functionality. See the help documentation for more caching commands and usage examples. See the help documentation for steps to replicate to other databases.

Other Operations

To retrieve SAP HANA data in PowerShell, call the Fill method of the OdbcDataAdapter method. To execute data manipulation commands, initialize the OdbcCommand object and then call ExecuteNonQuery. Below are some more examples CRUD commands to SAP HANA through the .NET Framework Provider for ODBC:

Retrieve SAP HANA Data

$sql="SELECT Name, OwnerId from Buckets" $da= New-Object System.Data.Odbc.OdbcDataAdapter($sql, $conn) $dt= New-Object System.Data.DataTable $da.Fill($dt) $dt.Rows | foreach { $dt.Columns | foreach ($col in dt{ Write-Host $1[$_] } }

Update SAP HANA Data

$cmd = New-Object System.Data.Odbc.OdbcCommand("UPDATE Buckets SET Name='TestBucket' WHERE Id = @myId", $conn) $cmd.Parameters.Add(new System.Data.Odbc.OdbcParameter("myId","001d000000YBRseAAH") $cmd.ExecuteNonQuery()

Insert SAP HANA Data

$cmd = New-Object System.Data.Odbc.OdbcCommand("INSERT INTO Buckets SET Name='TestBucket' WHERE Id = @myId", $conn) $cmd.Parameters.Add(new System.Data.Odbc.OdbcParameter("myId","001d000000YBRseAAH") $cmd.ExecuteNonQuery()

Delete SAP HANA Data

$cmd = New-Object System.Data.Odbc.OdbcCommand("DELETE FROM Buckets WHERE Id = @myid", $conn) $cmd.Parameters.Add(new System.Data.Odbc.OdbcParameter("myId","001d000000YBRseAAH") $cmd.ExecuteNonQuery()
