Re: SQL Question

Hi Ron:

Yes I have somes ideas, but I did not test them.

1. Example: Create view myview ... select a.invoice_number, b.item1, c.item2, d.item3, e.item4, ... from myheader a , ( select item item1 from myitems where invoice_number = a.invoice_number ) b , ( select item item2 from myitems where invoice_number = a.invoice_number ) c , ( select item item3 from myitems where invoice_number = a.invoice_number ) d , ( select item item4 from myitems where invoice_number = a.invoice_number ) e ...
2. Example: Create view myview ... select a.invoice_number, b.item1, c.item2, d.item3, e.item4, ... from myheader a , ( select item, invoice_number from myitems ) b , ( select item, invoice_number from myitems ) c , ( select item, invoice_number from myitems ) d , ( select item, invoice_number from myitems ) e where a.invoice_number = b.invoice_number (+) and a.invoice_number = c.invoice_number (+) and a.invoice_number = d.invoice_number (+) and a.invoice_number = e.invoice_number (+) ...
3. Or maybe: create view myview ... select invoice_number, item, 0, 0, 0, 0, ... from myitems where item =1 union select invoice_number, 0, item, 0, 0, 0, 0, ... from myitems where item =2 union ...

create view mysecondview
...
select invoice_number, item1, item2...
from myview
group by invoice_number.

I think they are not nice, but anyway I hope it helps.

Mabel,
