Azure Storage Icon Azure ODBC Driver

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

Access Azure Table Storage like you would a database - read, write, and update data through a standard ODBC Driver interface.

Replicate Azure Table Data from PowerShell


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



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

You can use the .NET Framework Provider for ODBC built into PowerShell to quickly automate integration tasks like replicating Azure Table data to other databases. This article shows how to replicate Azure Table 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 Azure Table

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.

Specify your AccessKey and your Account to connect. Set the Account property to the Storage Account Name and set AccessKey to one of the Access Keys. Either the Primary or Secondary Access Keys can be used. To obtain these values, navigate to the Storage Accounts blade in the Azure portal. You can obtain the access key by selecting your account and clicking Access Keys in the Settings section.

Connect to Azure Table

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

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

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

Retrieve Azure Table Data

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

Update Azure Table Data

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

Insert Azure Table Data

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

Delete Azure Table Data

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