Re: RPG/SQL

It's not clear that he wants it for the current year and previous - it could be any year and its previous, right?

So the you need to use parameter markers/host variables - can those be used in these CASE clauses? Recent posts suggest not.

Now if it IS current year and previous, then where you have "prior year" it could have "current year - 1"

This is what I was looking for - maybe simpler than the CTE solution I proffered.

I'd use a case statement for example
Select
Sum(case when year = prior year then sales else 0 end) as Prior_Year_sls,
Sum(case when year = current Year then sales else 0 end) as Current_year_sls

I think there are a couple typos in my reply - where I refer to tysales and lysales in the final SELECT. Check it out.

What type of select statement do I need to produce a data set containing:

Customer#
2011 sales
2012 sales

Generated from a file containing sales from several years.

I am using this statement:

exec SQL
declare stor_sls cursor for
select sdan8,
sum(sdaexp/100)
from f4211l9
where sdivd>=:j_start and sdivd<=:j_end and
sdlnty not in('T ', 'TN', '% ') and
sdmcu=:mcu group by sdan8
order by sum(sdaexp) desc;

This statement produces what I want for the given date range..i.e.

Customer#
2012 sales


but I need a separate field for the prior years sales

Do I declare a separate cursor for the prior year and then join the two???

Thanks in advance...
