How to pipe SAP HANA Data to CSV in PowerShell

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

Creating a Connection to Your SAP HANA Data

Set the Server, Database and Port properties to specify the address of your SAP Hana database to interact with. Set the User and the Password properties to authenticate to the server.

$conn = Connect-SAPHANA  -User "$User" -Password "$Password" -Server "$Server" -Database "$Database"

Selecting Data

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

Select-SAPHANA -Connection $conn -Table Buckets | Select -Property * -ExcludeProperty Connection,Table,Columns | Export-Csv -Path c:\myBucketsData.csv -NoTypeInformation

You will notice that we piped the results from Select-SAPHANA 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.

Deleting Data

The following line deletes any records that match the criteria:

Select-SAPHANA -Connection $conn -Table Buckets -Where "Name = TestBucket" | Remove-SAPHANA

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

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

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!
