I have a table AAA  which has 3 columns as Month_No,Year_No and Profit.
I want to select next 15 months profit data along with month and year from table AAA.
Can anyone help me to form the teradata Query for this?
Example:
Table Name:AAA
Month_No      Year_No    Profit
2                     2011       10

I am currently working on a requirement that deals with various effective spans for records. The final result should show overall effective spans per CUSTOMER_ID. However, date entries can be split up over multiple entries and locations:

CUSTOMER_ID SPONSOR LOCATION EFFECTIVE TERMINATION
ABC 123 100B 01/01/2010 03/15/2010
ABC 142 100C 03/01/2010 04/30/2010
ABC 301 300A 06/01/2010 08/15/2010
ABC 425 400B 06/15/2010 06/30/2010
ABC 259 300C 07/15/2010 12/31/2010
ABC 450 400C 10/01/2010 03/01/2011
