Powershell and Oracle: the strange couple

Here it is a nice guide to query an OracleDB using Powershell.
Basically install an Oracle Client (with .NET support), and define and use the following function (courtesy of PoshCode comunity):

function Get-OLEDBData ($connectstring, $sql) {            
   $OLEDBConn = New-Object System.Data.OleDb.OleDbConnection($connectstring)            
   $OLEDBConn.open()            
   $readcmd = New-Object system.Data.OleDb.OleDbCommand($sql,$OLEDBConn)            
   $readcmd.CommandTimeout = '300'            
   $da = New-Object system.Data.OleDb.OleDbDataAdapter($readcmd)            
   $dt = New-Object system.Data.datatable            
   [void]$da.fill($dt)            
   $OLEDBConn.close()            
   return $dt            
}

A test is here:

$connString = "password=pwd;User ID=id;Data Source=ambarabaciccicocco;Provider=OraOLEDB.Oracle"            
$query= "SELECT * FROM HR.DEPARTMENTS"            
Get-OLEDBData -connection $connString -sql $query
