It bites me all the time. Obviously it's totally insignificant since it's easy for my to just throw an "AS x" on the end of it. But damn. I see there's a comment foreseeing some annoyance value for this in the source: /* * The SQL spec does not permit a subselect * (<derived_table>) without an alias clause, * so we don't either. This avoids the problem * of needing to invent a unique refname for it. *That could be surmounted if there's sufficient * popular demand, but for now let's just implement * thespec and see if anyone complains. * However, it does seem like a good idea to emit * an error messagethat's better than "syntax error". */ So where can I officially register my complaint? :) -- greg
