Make one query of two queries?

Question

I have these two quries, how can I at the best way get the same result in one query?
--Querie 1
SELECT 'm' || Year_Month As Month,
Sum(NET_SALES) As "Net Sales"
FROM tlbInfo 
WHERE Year_Month Between '200709' And '200801'
And record_type IN ('A','X')
Group by Year_Month
Order by Year_Month
--Querie 2
SELECT 'm' || Year_Month As Month, 
Sum(STANDARD_MANUF_COST)/Sum(Case When SALES_QUANTITY <> '0' Then SALES_QUANTITY End) As "Cost",
to_char(100*((sum(NET_SALES)-sum(STANDARD_MANUF_COST))/sum(NET_SALES)) || '%') As "Margin"
FROM tlbInfo 
WHERE Year_Month Between '200709' And '200801'
And record_type NOT IN ('A', 'X')
And Net_Sales >0
Group by Year_Month
Order by Year_Month

Answer 1

why did you change the 1st query? now you're further from getting the correct answer (not to mention that now my previous post makes no sense).
put the 1st query back to the way it was. then change the 2nd query to remove the record_type and net_sales criteria from the where clause, and instead put the logic into the select, via a CASE, like the first query is written.
now look at the two new queries, and ask yourself, what's so hard about making one query?
and don't do this work in the original post. do it in notepad. and if you want to post the new queries here to get further help, hit the REPLY button, NOT THE EDIT BUTTON
