I work at a company that mainly does Java and PHP, as well as some old TCL. Alot of the code has these really big complex SQL queries where there is a select off of several tables and there is some nested inner select. It has occured to me in my advocacy of Rails that if I ever convinced them to take Rails more seriously and look into it that they might have some problem with the approach where in Rails you often don''t write those kinds of queries. Has anyone encountered that kind of criticism ? I am not really much of an SQL expert myself, though at times I have had to work with some of these queries, I''ve only been at this company for a year. I know you can do straight SQL in Ruby, but typically in Rails with active record, you wouldn''t do these kinds of complex queries. I feel quite content myself to steer away from that kind of thing if I can, but I''m not sure how to make a case of it with people who might have a problem with it. I also get skeptical sometimes if I can ever convince anyone of anything, so sometimes I never really worry how to present a really complete argument anyway .. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

This is a valid concern on behalf of management, but really it''s just making them look at things differently. Most of my apps end up with everything coded AR style to begin with, except in the case of AR just not being able to create the object that I want. (Yes it does happen I have a 30 line sql statement in one app, that I don''t even want to consider trying to write with AR). Mostly I find myself refactoring some of Rails ORM layer into sql in order to remove bottlenecks, but this is towards the end of a project. The thing is ORM has saved me so much time during development that I can afford to spend a day or two re-factoring some of the complex finds or strange inserts that AR might do into straight up sql. At the end of the day all that Rails is doing is implementing an ORM layer (Object Relational Mapping) just like Java does with Hibernate and even PHP does with CakePHP framework. Personally I''d just look at selling ORM to them if that is their concern with rails. There is a great screen cast from the Rails envy guys about Active Record ( not ActiveRecord, note the space ), it might be worth looking at before tackling management. http://www.railsenvy.com/2007/8/8/activerecord-tutorial Good luck, Cam On Jan 20, 12:29 pm, "wbsurf...-/E1597aS9LQAvxtiuMwx3w@public.gmane.org" <wbsurf...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> I work at a company that mainly does Java and PHP, as well as some > old TCL.

I have almost all of the major Rails and Ruby books in existence. I''ve done a bunch of fairly small websites on my own in Rails. I think I sort of realize myself why I like AR, I just am not that great of a salesman in some way perhaps. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
