Re: still dont' get how to group by

I don't believe you need the group by at all as I don't see any aggregate
functions (SUM(), COUNT(), AVG(), ect) being used.

Group by comes into play when some of the selected columns are using
aggregate functions _AND_ some are not. Any selected column not used in an
aggregate function must appear in the group by clause.

Example:
--Total Sales
select sum(qty * price) as Total_Sales
from saleshist

--Total sales by customer
select Customer, sum(qty * price) as Total_Sales
from saleshist
group by Customer

--Total sales by customer, item
select Customer, item, sum(qty * price) as Total_Sales
from saleshist
group by Customer, item

Why does this group by not work, what is it I need to do?

Column NAME or expression in SELECT list not valid.
CREATE VIEW PROJ_CRWN1/DATA_WHSV2 AS SELECT CUSTOMER#, NAME, STATE,
ITEM#, PROD_LINE, INVOICE#, ORD_DATE, INV_DATE, ORD_TYPE,
CUST_TYPE, QUANTITY, EXTENDED$ FROM Proj_Crwn1.DTAWHS
