  4. my focus is across a whole 3 years (156 weeks) of data, beginning January 1st 2011 (or nearest date) and ending December 31st 2013 (or nearest date) – so while we are looking at 3 years total, we will only end up with 52 weeks in our clean version of the data, labelled Week 1 to Week 52 (and not dates).there will be items in this list that launched before 1st Jan 2011, for which part of the launch year will show up in the period we’re focused on. In order that data percentiles (will be calculated at later stage) are not clouded by this, we also need to move any part year data from launches pre

    opinion about ORM

    Do you use ORM in your production or commercial application? I think ORMs are good for maintaining OO relation with datbase, But it has its limitation. For DML ORM is great for faster development and minimize duplication of code. But for DQL I think it is hard to do complex SQLs with ORM. Raw SQL would go along well. I have read somewhere it is not good to fit something like RDBMS to OO which it is not. Anyway i dont know how many open source and commercial application uses it. It looks like OSCommerce prefer to not use ORM. I have own written active record like ORM which uses Reflection

  17. My goal is to have users fill out three fields and click on a button that will check an sql table to see if there is a record with those three fields already in the database. I'm not 100% sure, but I think my issue is in my C# code calling the procedure. I have tested my stored procedure from sql and it works. I've tried a few things, but nothing is working. The code below is one of my attempts that isn't working. I'm not sure, but when I step through the program it doesn't appear to be calling the procedure (though I could be wrong and the problem is elsewhere). SqlConnection conn =

  20. Soooo I am taking a class called Electronic Commerce. My professor is is requiring us to make a website "selling" a product (not for real) and the website must use html 5, php and sql. He is not going to waste class time teaching us these because this is a "capstone" class and we should already be familiar. Well Html 5 I am ok with, but SQL and PHP, I am so lost. As far as I can figure out, the SQL is for my database. I have already gathered the jpgs, made a database of the spices with prices I will sell. I am not really sure how to attack this project and any help will by greatly ap

  22. Sir; I have developed a website for my Department of Science, which recently is hosted in USA. The website is programmed not to accept any form submissions after 8 pm. Also it gets redirected to "Site is down" page on Saturdays and Sundays. It was OK while the site was over in-house server. Now that its in USA, because the time zone now is different, it does not accept the forms after 8 pm in USA, which is 8 am here in India. Site does not accept forms from 8 am to 12 noon here in India. Also weekend redirect to "Site is down" is of no use due to date being different in USA and in India.

  25. I have a nifty query that pulls data by orders.orderid > '85000' (and I update that number every week based on orders.) But I want it to automatically pull the most recent 3,000 orders instead of changing that number all the time, so I was hoping to set a variable which is Max(order.orderid)-3000, thus pulling the last 3000 order records. Here is my static select: SELECT Orders.OrderID, Orders.OrderStatus, Orders.CustomerID, Orders.ShippingMethodID, Orders.BillingFirstName, Orders.BillingLastName, Orders.BillingAddress1, Orders.BillingAddress2, Orders.BillingCity, Orders.BillingState,
