Pipe Oracle Data to CSV in PowerShell

Use standard PowerShell cmdlets to access Oracle tables.

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

Creating a Connection to Your Oracle Data

To connect to Oracle, you'll first need to update your PATH variable and ensure it contains a folder location that includes the native DLLs. The native DLLs can be found in the lib folder inside the installation directory. Once you've done this, set the following to connect:

  • Port: The port used to connect to the server hosting the Oracle database.
  • User: The user Id provided for authentication with the Oracle database.
  • Password: The password provided for authentication with the Oracle database.
  • Service Name: The service name of the Oracle database.

$conn = Connect-OracleOCI  -User "$User" -Password "$Password" -Server "$Server" -Port "$Port"

Selecting Data

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

Select-OracleOCI -Connection $conn -Table Customers | Select -Property * -ExcludeProperty Connection,Table,Columns | Export-Csv -Path c:\myCustomersData.csv -NoTypeInformation

You will notice that we piped the results from Select-OracleOCI 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-OracleOCI -Connection $conn -Table Customers -Where "Country = US" | Remove-OracleOCI

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

Import-Csv -Path C:\MyCustomersUpdates.csv | %{
  $record = Select-OracleOCI -Connection $OracleOCI -Table Customers -Where ("Id = `'"+$_.Id+"`'")
  if($record){
    Update-OracleOCI -Connection $oracleoci -Table Customers -Columns ("CompanyName","City") -Values ($_.CompanyName, $_.City) -Where ("Id = `'"+$_.Id+"`'")
  }else{
    Add-OracleOCI -Connection $oracleoci -Table Customers -Columns ("CompanyName","City") -Values ($_.CompanyName, $_.City)
  }
}

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!
