  • SQL, problem with OrderBy / GroupBy

    - by Tristan
    Hi, In my table I have two fields among others : article_id and *version* *example: article_id : 5 // version 1 aricle_id: 5 // version 2 article_id: 6 // version 1* What i want to do is to retrieve the latest version for each article id (in my example i want to retrieve the article 5 version 2 object and article 6 and version 1 object). The problem is that mysql is doing the groupBy instead of the OrderBy so it returns to me the FIRST version of each article, but i want the opposit. Do you have an idea please ?

  • Database structure for versioning and multiple languages

    - by phobia
    How can I solve the issue of content existing in multiple versions and multiple languages? My current structure: Each content can only have one active version in each language, and that's how I'm curious on how to best solve. Right now I have a column of the contentversions table, which means for each change of active version I have to run a update and set active=false on all version and then a update to set active=true for the piece of content in question.

  • jqueryUI Slider: Setting minimum and maximum values in range from DB

    - by alexBrand
    I have a jQueryUI slider on my website that deals with price range. I have a products table in mysql that has various entries. I am using the slider to filter the results, but I need to set the minimum and maximum prices from the records in my database. Should I just generate (with php) hidden fields in my html that contain the minimum and maximum and then use jQuery to obtain them? Or is there a better way of achieving this, maybe using AJAX? Thanks
