Some SQL trouble

[Beacher]

Hello all.
I'm creating a view, and part of it.. one of the fields, i sum lets say
hours + line hours As TotalHours, itll find the 3 records, sum them,
and give me the correct amount of hours.. but I also have another field
that is totalhours / product made .. I need this to also show in the
view, but i first have to sum the total hours field. I tried doing
(SELECT Sum(hours+linehours) from table) / productmade but it gives me
the error about using an aggregate function in a group by or sum list?
Anyways, I'm not too great in SQL so if anyone has any ideas, id
greatly appreciate it. I can paste the code if it will help at all, but
its rather lengthy.

TIA

I assume productmade is a number. How do you derive the productmade
number? Does it come from the same table as hours, linehours? How does
productmade relate to hours, linehours?

what is your initial query GROUP ed BY ?
ie SELECT SUM(hours + lineHours) as totalHours FROM table GROUP BY
something

you need the same GROUP BY in
(SELECT Sum(hours+linehours) from table group by something) /
productmade

the SUM function is an aggregate function (like COUNT, FIRST, MIN, MAX,
etc) which needs a GROUP BY clause

you can also have
SELECT SUM(hours + lineHours) as totalHours
SUM(hours + lineHours) / productMade as foobar
FROM table
GROUP BY something
