I will like to produce a query which generates the life cycle of orders on the different products present in the company.
The order of the products for each item from when it was lunched in the market is available in Table 1. The product can start having orders from when it was lunched or there can be a month where orders were absent (AX1). Another possibility is that the product may start having orders some few months later from it was presented over the market.
The launch dates for each product are present in table 2
I will like to have for each product the monthly order from when it was launched under a common monthly timescale distribution. The monthly distribution is an incremental month distribution from the respective launched date to present date.
Month1 is the launched date each product, Month 2 is the second month from the launched date ( eg. AX1 200810, BY1 200910) and so on. The resultset I am expecting is in Table 3.
How can I achieve it
Product Date Order
AX1 200810 29
AX1 200812 13
AX1 200902 45
BY1 200909 5
BY1 200910 7
BY1 200911 3
BY1 200912 4
CZ1 201111 4
CZ1 201112 6
CZ1 201201 10
