Create multiple lines from a table

[ecabanas]

Hi all,

I want to create a table with the (creating a unique code that identifies the customer&month)customers  that buys a freepass. I created a table from the initial order that "starts" the freepass period (90 days)

This is the table:

created_at	Custaccount	Quarterly_DPASS	SalesBOid	QUARTELY_DPASS_ID
02/01/2017	C000039	21134283	PV00405616	C000039-2017-1
02/01/2017	C002711	21134283	PV00405617	C002711-2017-1
02/01/2017	C052805	21134283	PV00405618	C052805-2017-1
02/01/2017	C063701	21134283	PV00405621	C063701-2017-1

ant the result has to 3 lines per each line. Each one for present created_at code, +30 days created_at, +60days created_at

thank you very much for your help
