And I guess we could just use other databases that actually conform to a wide spread standard and just forget about SQLite. This little "feature" is the only thing keeping me from carrying SQLite implementations beyond "trivial." I guess I spent too many years having to avoid the grey areas in IBM manuals, to want to do that again. Lets see now, I have a multi thousand line SQL based implementation based in another database. I am considering switching platforms. To move to one I basically move the bare SQL over and go. With my other possible platform, I must track down, modify every occurrence of a returned column name to implement "AS", test and debug all this, and... Guess what I'm going to do...
