I often have SQL queries that I know will only return a single item, and it's much easier to read the results if it I can access it like "Query.data.FieldName" instead of "Query.data.FieldName['0']". So I usually add "return formatDataAsArray(data)['0']" to the query transformer. Not hard, but I do it often so it'd be nice if there was a checkbox that you could check that told the system it was only going to get one record back and to do that part automatically.
was also looking for such functionality, thanks for the tip as it makes accessing fields easier
