You can use .NET Oracle library DLL, just make sure you have the required DLL file under the lib folder

Add-Type -Path "lib\Oracle.ManagedDataAccess.dll"

$query = "select  1 as Col1, 2 as Col2, 3 as Col3 from dual
          union
          select  4 as Col1, 5 as Col2, 6 as Col3 from dual
          union
          select  7 as Col1, 8 as Col2, 9 as Col3 from dual"

$cn   = New-Object Oracle.ManagedDataAccess.Client.OracleConnection -ArgumentList "TNS-ConnectionString-Here"
$cmd  = New-Object Oracle.ManagedDataAccess.Client.OracleCommand    -ArgumentList $query

$cmd.Connection = $cn

try {
    $cn.Open()

    $reader = $cmd.ExecuteReader()

    while ($reader.Read()) {
        $col1 = $reader["Col1"]
        $col2 = $reader["Col2"]
        $col3 = $reader["Col3"]

        Write-Host $col1, $col2, $col3
    }

} catch {
    Write-Error $_.Exception.Message
} finally {
    $cmd.Dispose()
    $cn.Dispose()
}
