  • Advanced count and join in Rails

    - by trobrock
    I am try to find the top n number of categories as they relate to articles, there is a habtm relationship set up between the two. This is the SQL I want to execute, but am unsure of how to do this with ActiveRecord, aside from using the find_by_sql method. is there any way of doing this with ActiveRecord methods: SELECT "categories".id, "categories".name, count("articles".id) as counter FROM "categories" JOIN "articles_categories" ON "articles_categories".category_id = "categories".id JOIN "articles" ON "articles".id = "articles_categories".article_id GROUP BY "categories".id ORDER BY counter DESC LIMIT 5;

IdCategory : bigint (FK) How do I recursively count all Questions for a given Category (including questions in subcategories). I've tried it already based on several tutorials but still can't figure it out :(

  • Current tasks count at Appengine Task Queue

    - by splix
    Are there any ways to get count of current unfinished tasks at Google Appengine development server? I need it for making my integration test. I found a way to get this when running it local (just in mem), as described at appengine docs. But when i'm running it as a standalone server, from maven, this doesn't work. Just because library appengine-testing conflicts with Appengine SDK classes, and i can't use those classes together, when running sdk dev server.

  • Pointers, links, object and reference count

    - by EugeneP
    String a = "a"; // allocate memory and write address of a memory block to a variable String b = "b"; // in a and b hold addresses b = a; // copy a address into b. // Now what? b value is completely lost and will be garbage collected //* next step a = null; // now a does not hold a valid address to any data, // still data of a object exist somewhere, yet we cannot get access to it. Correct me if there's a mistake somewhere in my reflexions. My question is: suppose anInstance object of type Instance has a property ' surname ' anInstance.getSurname() returns "MySurname". now String s = anInstance.getSurname(); anInstance = null; question is - is it true that getSurname value, namely MySurname will not be garbage collected because and only because it has active reference counter 0, and if other properties of anInstance have a zero reference counter, they'll be garbage collected?

  • Count of products NOT sold...per store, per day over the past month

    - by user1893510
    I'm struggling with an interview question. 3 dimension tables (Product, Store and Date) and 1 fact table (Sales). The question asks for a T-SQL solution that will return the count of products not sold, per store, per day over the past month. At this point, my answer is futile but I've spent significant time trying to back into a solution, to no avail, and would like to close the loop. Any guidance is greatly appreciated.
