I'm a bit confused as to what you're trying to count and total. It looks to me like you're now doing a count and price by item, whereas before you wanted a grand total. IF you want a count and price by item, you'd just do:
SELECT itemname, SUM(pricecolumn) as totalpricebyitem, COUNT(itemid) AS countbyitem FROM yourtables group by itemname On 7/12/05, daniel kessler <[EMAIL PROTECTED]> wrote: > >When you ask Oracle to group by a particular column, it looks for like > >values within that column and groups those rows of data together. > >Let's look at some sample data. > > > >CustID PricePaid Date > >1 .50 5/1/05 > >1 .75 5/7/05 > >2 1.00 6/1/06 > >2 .50 5/1/05 > > > > So, why would I get the error, "not a group by expression" when I add a > column to the group by?
