Re: Why is "group by" obligatory in SQL?

Thanks Walter for your answer. In my mind there was an intelligent parser, which always knows whether to aggregate (if there is an aggregate function) or not (if not). I don't know if it was difficult to program such an parser but the way SQL is defined you might need to write a couple of words more but at least it is clear. At least regarding the grouping. Thanks again for shedding light on the aspects you mentioned.

Best,
