Stored Procedure on IBM i seems

Question

I need guidance in the best way to do this. I ran a report that shows the part#'s that had no sales for the 'past 2 months'. Let's assume for now that this will run at the beginning of each month. I did this as hard coded and this needs to be automated to run in a crystal report. The way I did this was 4 queries. the first picks the items which are 'Available to sell' and inventoried. It seems we can easily make this into a view.

this second one here picks the items which had sales in the 2 months in question. Should this be a stored procedure? if so, I have no previous exp. with SP on the IBM i. But it seems to me the sp is best.

Here we are selecting records when there has been sales in the 4th or 5th months. this is hard coded. We need to do this for the past 2 months at all times. if the program is being run in June then we need to look at May and April. The year should be accordingly. Current year unless we are running this in Jan-Feb. then we want Nov-Dec 2013 etc.

Creating an SQL stored procedure on IBM i is very similar to creating a stored procedure on any other platform. CREATE PROCEDURE is the SQL command. You can issue that command via the green screen STRSQL command, the GUI IBM i Navigator or IBM i Access for Web. You can also use an ODBC or JDBC connection if you prefer.

All of the IBM i reference material can be located in the Knowledge Center For v7.1, the direct link to the stored procedures is http://www-01.ibm.com/support/knowledgecenter/ssw_ibm_i_71/sqlp/rbafysproeg.htm?lang=en The navigation path is IBM i 7.1 > Database > Programming > SQL programming > Routines > Stored procedures.
