How can I pull only latest product made by Cash on every first payment done?
1 transaction have unique ID and can purchase few products in different time.
I tried to pull as below but it still pull out Cash.

ID Payment PaymentDate PaymentMethod
123 $20 2012-01-10 Debit Card
123 $50 2012-01-20 Cash
234 $10 2012-01-30 Cash
234 $80 2012-02-20 Visa

I would like output as below:
ID Payment PaymentDate PaymentMethod
234 $10 2012-01-30 Cash

What I meant is I just want the output for every first transaction which use Cash.
ID 123 first transaction is Debit Card according to the payment date.
It should not appear in the output.
