Pipe OData Services to CSV in PowerShell

Use standard PowerShell cmdlets to access OData tables.

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

Creating a Connection to Your OData Services

The User and Password properties, under the Authentication section, must be set to valid OData user credentials. In addition, you will need to specify a URL to a valid OData server organization root or OData services file.

$conn = Connect-OData  -URL "$URL" -UseIdUrl "$UseIdUrl" -OData Version "$OData Version" -Data Format "$Data Format"

Selecting Data

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

Select-OData -Connection $conn -Table Orders | Select -Property * -ExcludeProperty Connection,Table,Columns | Export-Csv -Path c:\myOrdersData.csv -NoTypeInformation

You will notice that we piped the results from Select-OData 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-OData -Connection $conn -Table Orders -Where "ShipCity = New York" | Remove-OData

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

Import-Csv -Path C:\MyOrdersUpdates.csv | %{
  $record = Select-OData -Connection $OData -Table Orders -Where ("Id = `'"+$_.Id+"`'")
  if($record){
    Update-OData -Connection $odata -Table Orders -Columns ("OrderName","Freight") -Values ($_.OrderName, $_.Freight) -Where ("Id = `'"+$_.Id+"`'")
  }else{
    Add-OData -Connection $odata -Table Orders -Columns ("OrderName","Freight") -Values ($_.OrderName, $_.Freight)
  }
}

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!
