You've definitely missed the point because you're concerned about the "very end of the query". I'm describing both a reporting and more importantly as far as I'm concerned an explorative process that's disrupted by the silly need to list out all columns. Performance is irrelevant.
- tome 4y agoYes, I know I've missed the point. That's why I asked my question in the first place! My question was: > What's the use case for that? In fact, I can hardly understand the benefit of projecting at all, except at the very end. Why would you want to do it? Is there a performance benefit? and I meant it literally. It's not an oblique, rhetorical way of saying "you don't need to do this". It was a genuine question! You've answered that it's convenient when doing exploratory work. Thank you. That helps me understand better.
