Replicate Hugging Face Data from PowerShell

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

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

You can also write PowerShell code to download Hugging Face data. See the examples below.

Create an ODBC Data Source for Hugging Face

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.

HuggingFace Hub uses token-based authentication to enable access to its API. The API provides access to machine learning models, datasets, spaces, papers, and other resources on the HuggingFace Hub platform.

Using API Key Authentication

To authenticate to HuggingFace Hub, you will need to provide an API Key (Access Token). To obtain your access token:

1. Log in to your HuggingFace account at https://huggingface.co
2. Navigate to Settings > Access Tokens
3. Click "New token" to create a new access token
4. Select the appropriate permissions (read or write)
5. Copy the token value

After obtaining your access token, set the following connection properties:

• AuthScheme: Set this to APIKey.
• APIKey: Set this to your HuggingFace access token.

Example connection string

Profile=C:\profiles\HuggingFace.apip;ProfileSettings='APIKey=hf_xxxxxxxxxxxxxxxxxxxx';

Connect to Hugging Face

The code below shows how to use the DSN to initialize the connection to Hugging Face data in PowerShell:

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

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

Retrieve Hugging Face Data

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