Below the query I created to get certain itemnumbers, qty ordered and price and others from the database. The problem is that sometimes an order doesn’t contain 20 itemsnumbers but only 2. Now my question is if it’s possible to fill the spaces with other itemnumbers random from the DB. It doesn’t need to be correct because it’s just for testing.
So can anybody help?
select
t.*,
-- THE THREE SUMVAT VALUES BELOW ARE VERY IMPORTANT. THEY ARE ONLY CORRECT HOWEVER WHEN THERE ARE NO NULL VALUES INVOLVED IN THE MATH,
-- I.E. WHEN THERE ARE 20 ITEMS/QTYS/PRICES INVOLVED WITH A CERTAIN ORDER_NO
((t.QTY1*t.PRICE1)+(t.QTY2*t.PRICE2)+(t.QTY3*t.PRICE3)+(t.QTY4*t.PRICE4)+(t.QTY5*t.PRICE5)) SUMVAT0, -- example: 5123.45 <- lines 1-5: Q*P

Without being able to really test this, you might try something like this. Replace the inline view ‘x’ with this:
The WITH clause will give you a table with 20 rows of random data. Outer join that with your old ‘x’ data and you will be guaranteed 20 rows of data. You might not need to cast the item as a varchar2 depending on data. (N.B., I finally found a query that it makes sense to use a RIGHT JOIN with. See this SO question)
I’m not quite sure what you’re trying to do with the GROUP BY and MAX stuff? In the future it would be helpful to condense your examples into something others can easily test, a minimal case that gets your point across.
I also incorporated @Kevin’s good suggestion to use ROW_NUMBER instead of RANK.
