  • Avoid writing SQL queries altogether in SSIS

    - by Jonn
    Working on a Data Warehouse project, the guy that gave us the tutorial advised that we stick to using SQL queries over defining a lot of data flow transformations, citing points like it'll consume a lot of memory on the ETL box so we'd rather leave the processing to the DB box. Is this really advisable? Where's the balance between relying on GUI tools over executing a bunch of SQL scripts on your Integration package? And honestly, I'd like to avoid writing SQL queries as much as I can.

  • MySQL - Order results by relevancy, LEFT JOINS and more

    - by XaviEsteve
    Hi guys, I am trying to get some results ordered by total votes (where client votes count 2 points and other people votes are 1 point). tab_names: +-----------+ | Name | id | +------+----+ | John | 1 | | Paul | 2 | +------+----+ tab_votes: +--------+-----------+ | idname | ip | +--------+-----------+ | 2 | 127.0.0.1 | | 2 | 127.0.0.1 | | 2 | 82.23.5.1 | | 1 | 127.0.0.1 | +--------+-----------+ This is the MySQL query I've got but doesn't work: SELECT * COUNT(v.idname) AS totalvotes, (SELECT COUNT(v.ip) FROM tab_votes WHERE v.ip LIKE '$ip') AS uservotes FROM tab_names n LEFT JOIN tab_votes v ON n.id = v.idname GROUP BY n.name ORDER BY uservotes DESC, totalvotes DESC LIMIT 40

  • Set textarea selection in Internet Explorer

    - by Tatu Ulmanen
    I'm looking for a way to set a selection in a textarea in Internet Explorer. In other browsers, this works just fine: textarea.selectionStart = start; textarea.selectionEnd = end; In IE, I assume I have to use createRange and adjust the selection somehow, but I cannot figure out how. Extra bonus points for a link to a proper documentation about createRange and associated methods, MSDN isn't helping out much.

  • Using the masters method

    - by Roarke
    On my midterm I had the problem: t(n) = 8T(n/2) +n^3 and I am supposed to find its big theta notation using either the masters or alternative method. So what i did was a = 8, b = 2 k = 3 log8 (base 2) = 3 = k therefore, T(n) is big theta n^3. I got 1/3 points so i must be wrong. What did I do wrong?

  • What are the best practices for implementing the == operator for a class in C#?

    - by remio
    While implementing an == operator, I have the feeling that I am missing some essential points. Hence, I am searching some best practices around that. Here are some related questions I am thinking about: How to cleanly handle the reference comparison? Should it be implemented through a IEquatable<T>-like interface? Or overriding object.Equals? And what about the != operator? (this list might not be exhaustive).

  • How to validate a Singaporean FIN?

    - by abigblackman
    Can anyone provide an algorithm to validate a Singaporean FIN? I know with a Singaporean NRIC I can validate it via modulo 11 and then compare the result to a lookup table but cannot find a similar lookup table for the FIN. I also do not know for sure if the modulo 11 is the correct method to validate. I am aware the government sells a algorithm for $400 but maybe someone knows a cheaper way. Bonus points for c# implementation.

    Guys I know this question is silly but just to make sure: Having in my class method: boolean equal(Document d) { //do something } I'm overloading this method nor overriding right? I know that this or similiar question will be on upcoming egzam and would be stupid to not get points for such a simple mistake;

    - by Matt
    What I am looking for currently is a simple, basic, login credentials sanitation script. I understand that I make a function to do so and I have one...but all it does right now is strip tags... am I doomed to use replace? or is there a way i can just remove all special characters and spaces and limit it to only letters and numbers...then as for the password limit it to only letters and numbers exclimation points, periods, and other special chars that cannot affect my SQL query. Please help :/ Thanks, Matt

The connection rules describe how two graphs out of B can be linked together. Linking points are marked vertexes. Find all combination of graphs in B that contain g as a subgraph. Regards Mac

    - by phoebebright
    I have pisa producing .pdfs in django in the browser fine, but what if I want to automatically write the file to disk? What I want to do is to be able to generate a .pdf version file at specified points in time and save it in a uploads directory, so there is no browser interaction. Is this possible?

  • Sprite to Line Collision

    - by Alu
    If I have a sprite, how would I check collision between two points? For example, in a game I am making, I would like to draw multiple lines that my sprite collides against. I'm thinking that this is more flexible than other collision systems if I had a lot of platforms.

  • Can I change the temp folder path?

    - by roufamatic
    I have an asp.net app that uses System.IO.Path.GetTempFileName() for temporary files. In the production IIS environment (W2K3), the temp folder (System.IO.Path.GetTempPath()) points to C:\Windows\Temp. But on my XP dev machine it's C:\documents and settings\machinename\ASPNET\temp. Is it possible to change this folder without affecting other accounts on my machine?
