Azure Analysis Services ODBC Driver

The Azure Analysis Services ODBC Driver is a powerful tool that allows you to connect with live data from Azure Analysis Services, directly from any applications that support ODBC connectivity.

Access Azure Analysis Services data like you would a database - read, write, and update Azure Analysis Services AnalysisServicesData, etc. through a standard ODBC Driver interface.



Write a quick PowerShell script to query Azure Analysis Services data. Use connectivity to the live data to replicate Azure Analysis Services data to SQL Server.



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

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

You can also write PowerShell code to download Azure Analysis Services data. See the examples below.

Create an ODBC Data Source for Azure Analysis Services

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 Azure Analysis Services, set the Url property to a valid server, for instance, asazure://southcentralus.asazure.windows.net/server, in addition to authenticating. Optionally, set Database to distinguish which Azure database on the server to connect to.

Azure Analysis Services uses the OAuth authentication standard. OAuth requires the authenticating user to interact with Azure Analysis Services using the browser. You can connect without setting any connection properties for your user credentials. See the Help documentation for more information.

Connect to Azure Analysis Services

The code below shows how to use the DSN to initialize the connection to Azure Analysis Services data in PowerShell:

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

Back Up Azure Analysis Services 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 " + $Customer $cmd = New-Object System.Data.Odbc.OdbcCommand($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 Azure Analysis Services 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 Azure Analysis Services through the .NET Framework Provider for ODBC:

Retrieve Azure Analysis Services Data

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