Hi Albert,

I think the way it should be handled is that you split the SQL into two different SQL statements. The first one will just have the primary key field and the fields being aggregated, then you join the result of that SQL with the original table to get the other fields that you want.

I have quite a few spots where I grouped by a single field or two before but now this needs updating. Some SELECT statements have a lot of fields so I don't relish adding all the new fields to the GROUP BY list.
