Replicate SAP Business Warehouse Data from PowerShell

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

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

You can also write PowerShell code to download SAP Business Warehouse data. See the examples below.

Create an ODBC Data Source for SAP Business Warehouse

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.

To connect to SAP Business Warehouse, set the URL property to a valid SAP Business Warehouse server base URL. The driver must connect to SAP Business Warehouse instances hosted over HTTP with XMLA access.

The driver supports the following authentication schemes via the AuthScheme property:

• None: Anonymous authentication, if available on the server.
• Basic: Set User and Password and set AuthScheme to Basic.
• Kerberos: See the Using Kerberos section of the help documentation for the required Kerberos properties.

By default, the driver attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store. To specify another certificate, see the SSLServerCert property for the available formats.

Connect to SAP Business Warehouse

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

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

Back Up SAP Business Warehouse 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 " + $Sales
$cmd = New-Object System.Data.Odbc.OdbcCommand($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 Business Warehouse 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 commands to SAP Business Warehouse through the .NET Framework Provider for ODBC:

Retrieve SAP Business Warehouse Data

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