Pipe Azure Table Data to CSV in PowerShell

Use standard PowerShell cmdlets to access Azure Table tables.

The CData Cmdlets Module for Azure Table is a standard PowerShell module offering straightforward integration with Azure Table. Below, you will find examples of using our AzureTables Cmdlets with native PowerShell cmdlets.

Creating a Connection to Your Azure Table Data

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.

$conn = Connect-AzureTables  -AccessKey "$AccessKey" -Account "$Account"

Selecting Data

Follow the steps below to retrieve data from the NorthwindProducts table and pipe the result into to a CSV file:

Select-AzureTables -Connection $conn -Table NorthwindProducts | Select -Property * -ExcludeProperty Connection,Table,Columns | Export-Csv -Path c:\myNorthwindProductsData.csv -NoTypeInformation

You will notice that we piped the results from Select-AzureTables into a Select-Object cmdlet and excluded some properties before piping them into an Export-Csv cmdlet. We do this because the CData Cmdlets append Connection, Table, and Columns information onto each "row" in the result set, and we do not necessarily want that information in our CSV file.

The Connection, Table, and Columns are appended to the results in order to facilitate piping results from one of the CData Cmdlets directly into another one.

Deleting Data

The following line deletes any records that match the criteria:

Select-AzureTables -Connection $conn -Table NorthwindProducts -Where "ShipCity = New York" | Remove-AzureTables

Inserting and Updating Data

The cmdlets make data transformation easy as well as data cleansing. The following example loads data from a CSV file into Azure Table, checking first whether a record already exists and needs to be updated instead of inserted.

Import-Csv -Path C:\MyNorthwindProductsUpdates.csv | %{
  $record = Select-AzureTables -Connection $AzureTables -Table NorthwindProducts -Where ("Id = `'"+$_.Id+"`'")
  if($record){
    Update-AzureTables -Connection $azuretables -Table NorthwindProducts -Columns ("Name","Price") -Values ($_.Name, $_.Price) -Where ("Id = `'"+$_.Id+"`'")
  }else{
    Add-AzureTables -Connection $azuretables -Table NorthwindProducts -Columns ("Name","Price") -Values ($_.Name, $_.Price)
  }
}

As always, our goal is to simplify the way you connect to data. With cmdlets users can install a data module, set the connection properties, and start building. Download Cmdlets and start working with your data in PowerShell today!
