Pipe WordPress Data to CSV in PowerShell

Use standard PowerShell cmdlets to access WordPress tables.

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

Creating a Connection to Your WordPress Data

To connect to WordPress, set the URL property and other authentication properties. WordPress supports Basic (User and Password) and OAuth2.0 authentication, though Basic is recommended for a testing environment only. To connect with OAuth you will need to register an app with WordPress.

See the Getting Started guide in the CData driver documentation for more information.

$conn = Connect-WordPress  -Url "$Url"

Selecting Data

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

Select-WordPress -Connection $conn -Table Categories | Select -Property * -ExcludeProperty Connection,Table,Columns | Export-Csv -Path c:\myCategoriesData.csv -NoTypeInformation

You will notice that we piped the results from Select-WordPress 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-WordPress -Connection $conn -Table Categories -Where "Id = 1" | Remove-WordPress

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 WordPress, checking first whether a record already exists and needs to be updated instead of inserted.

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

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!
