I need to build a select statement with fields/columnnames that do not need an aggregate function (SUM, MAX etc), but since i do have a field that gets a SUM function and goes into the GROUP BY clause, i get an error on my one field: "this field needs to be in an Aggregate function to be included in the Group By clause."
I went ahead and included the field in the group by , and I did not get an error. Is this still legit in SQL ad hoc queries?

From what you describe, it sounds legit, but it also depends on what you actually want. What is your select statement?

Each field you include in the Select statement that does Aggregate need to be included in Group by Clause

If you need additional columns from the rows that satisfy the aggregate, then you can do this with a derived table. Show us your SELECT statement, the one that doesn't work, and we'll show you how to do it with the use of a derived table.
