SAS Data Sets Data Cmdlets

An easy-to-use set of PowerShell Cmdlets offering real-time access to SAS Data Sets. The Cmdlets allow users to easily read, write, update, and delete live data - just like working with SQL server.



Use standard PowerShell cmdlets to access SAS Data Sets tables.

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

Creating a Connection to Your SAS Data Sets Data

Set the following connection properties to connect to your SAS DataSets files:

  • URI: Set this to the folder containing your .sas7bdat resources. Currently we only support local files.

$conn = Connect-SASDataSets  -URI "$URI"

Selecting Data

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

Select-SASDataSets -Connection $conn -Table restaurants | Select -Property * -ExcludeProperty Connection,Table,Columns | Export-Csv -Path c:\myrestaurantsData.csv -NoTypeInformation

You will notice that we piped the results from Select-SASDataSets 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-SASDataSets -Connection $conn -Table restaurants -Where "cuisine = American" | Remove-SASDataSets

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

Import-Csv -Path C:\MyrestaurantsUpdates.csv | %{
  $record = Select-SASDataSets -Connection $SASDataSets -Table restaurants -Where ("Id = `'"+$_.Id+"`'")
  if($record){
    Update-SASDataSets -Connection $sasdatasets -Table restaurants -Columns ("name","borough") -Values ($_.name, $_.borough) -Where ("Id = `'"+$_.Id+"`'")
  }else{
    Add-SASDataSets -Connection $sasdatasets -Table restaurants -Columns ("name","borough") -Values ($_.name, $_.borough)
  }
}

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!
