Question

I have a column for group name and a column for amount spent.
I need to sum the amounts group them based on the group name and then grab the highest five. After that, I need to combine the the rest into it’s own group w/ a total of their amount spent. This is what i have right now

SELECT groupName, SUM(amount) AS theAmountSpent
FROM purchases
GROUP BY groupName
ORDER BY theAmountSpent DESC

This groups and orders them, but i dont know how to then grab the remaining groups to combine them. Any help would be appreciated.

If I’m understanding you correctly, this should do it:

SELECT top 5 groupName, SUM(amount) AS theAmountSpent
into #tempSpent FROM purchases
GROUP BY groupName
ORDER BY theAmountSpent DESC

Select * from #tempSpent -- get the top 5

--get sum for the rest
SELECT SUM(amount) AS theAmountSpent
FROM purchases
where groupName not in (select groupName from #tempSpent)

Drop table #tempSpent
