Hi,
I have a table containing the following columns:
ProdGroup,   ProductID, PercentFat, PercentProt.

I would like to be able to get the average PercentFat and PercentProt per ProdGroup.
The fields are all of type INT. There are multiple ProductIDs within each ProdGroup.

So to be able to return one row for each ProdGroup, together with the average percentage PercentFat  and PercentProt

Any assistance would be appreciated
Thanks

Select ProdGroup, AVG(PercentFat) as Avg_PercentFat, AVG(PercentProt) as Avg_PercentProt
From MYTABLE
Group By ProdGroup
Order By ProdGroup

Open in new window


This assumes that you are happy in having the averages as INTs.
