windows powershell: execute select against an oracle instance. (System.Data.OracleClient)

in no way a powershell guy, but

powershell script:

[Reflection.Assembly]::LoadWithPartialName("System.Data.OracleClient") > null

 $connection=New-Object DATA.OracleClient.OracleConnection(
    "Data Source=eoxi;User Id=eoxrep;Password=***"
    )
   
 $connection.Open()
 $reader = (new-Object DATA.OracleClient.OracleCommand(
    "select * from eox.eox_log_ereignis_a where rownum < 10",
    $connection)).ExecuteReader()

 while( $Reader.Read()) {
    $id   = $reader["log_id"]
    $time = $reader["log_log_area"]
    write-output "$id $time"
 }
 $connection.Close()

executes as:

oracle select
