Ever have one of those moments where you push send and said doh. Shouldn't have sent that.

I figured it came across wrong. I don't like to just give the answer. I don't like asking for an answer either like I was looking for this week.

I was having same issue, no help on the Internet.

I finally found my answer by experimenting.

Anyway.

Select item, dateofsale, sum(amount)
From file
Group by rollup (item, dateofsale)

This will give you an amount by item and date along with break totals.

With the group by, you have to explicitly list out the fields. Any field selected without an aggregate function must also be in the group by.

However, you may group by a field that's not in the select list.

You shouldn't put a field that's in a aggregate function in the group by too.

I plead guilty. At the moment I am a bit angry with myself for not having discovered sql earlier. So far my problems with sql have tended toward my over-thinking the tasks. This group by issue is one more example of a simple answer that I could not find.

The problem I am having with Googling for answers is that I don't know yet how to frame the questions in a way to get answers that relate.

In any event, I do appreciate the courtesy and the answers. Its been pleasing.

Booth, from what I remember you were good at what you do! So I'm wondering why you are posting such a simple question.

You need to google "group by clause". Simple search will lead to what you are doing wrong.

I will also recommend googling "group by rollup" clause
