Script to Create OLEDB Connection

Need help in establishing OLEDB connection to the database, i am using the below script to connect to a oracle database, When i run the script the output is not showing all the records/ data. Enclosed my output window at the bottom.

 [System.Reflection.Assembly]::LoadWithPartialName("System.Data.OracleClient")
 
$connectionString = "Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(Host=XXXXXXX)(Port=1535)))(CONNECT_DATA=(SID=ABCD)));User ID=giltest;Password=XXXXXXXX"

$connection = New-Object System.Data.OracleClient.OracleConnection($connectionString)

$queryString = "SELECT PRODUCT_NAME FROM PRODUCTS"

$command = new-Object System.Data.OracleClient.OracleCommand($queryString, $connection)

$connection.Open()

$productNames = $command.ExecuteScalar();

write-host "List of the Products:" $productNames | ft

$connection.Close()
