Apologies everyone, I had that backward.
Select field1, count(*)
From file 1
Group by field1, field2

I found something interesting the other day. You can have fields in your group by clause that are not in the select clause.
Select field1, count(*)
From file1
Group by field1, field2
This gives a really weird looking results set and so I and was wondering if anyone could give me a reason that you would do something like this.
Full disclosure…how I found this was that I missed a comma in my select statement. 😊
