  • Emulating a "OR" condition in Datastore.

    - by Jelle
    Hello again, I'm using the Google App Engine with Python (Django). How to emulate "SELECT * FROM bla WHERE touser = common.userstats("key") OR fromuser = common.userstats("key") ORDER BY date ASC"? I was thinking of something like this, but I can't get it in the order I want. recievedlist = models.P1.all() recievedlist.filter("touser =", common.userstats("key")) plus1list = recievedlist.fetch(50) sendlist = models.P1.all() sendlist.filter("fromuser =", common.userstats("key")) plus1list += sendlist.fetch(50) # order plus1list

  • How can I use linq to initialize an array of repeated elements?

    - by Eric
    At present, I'm using something like this to build a list of 10 objects: myList = (from _ in Enumerable.Range(0, 9) select new MyObject {...}).toList() This is based off my python background, where I'd write: myList = [MyObject(...) for _ in range(10)] Note that I want my list to contain 10 instances of my object, not the same instance 10 times. Is this still a sensible way to do things in C#? Is there a cost to doing it this way over a simple for loop?

  • Why doesn't SQL DISTINCT work with ORDER BY CAST?

    - by Tommy
    Including DISTINCT to an SQL query that also uses ORDER BY CAST(thecolumn AS int) as shown here seems to remove that sorting functionality. Any reason these cant work together? (Using sqlite with the C api) Thanks. EDIT: Started with - sprintf(sql, "SELECT DISTINCT rowX FROM TableX Order By Cast(rowX As int) LIMIT 150 OFFSET %s;", Offset); rowX is Type CHAR(5)

  • MySQL query String contains

    - by arik-so
    Hello. This may sound easy, but I've been trying - in vain, apparently - to figure out how I can make a query with MySQL that checks if the value (string $haystack ;) ) in a certain column contains certain data ( $needle ;) ), like this: mysql_query(" SELECT * FROM `table` WHERE `column`.contains('{$needle}') "); In PHP, the function is called substr($haystack, $needle), so maybe: WHERE substr(`column`, '{$needle}')=1 Thanks in advance!

  • Dual parameters for same value

    - by n0chi
    Is it possible to have 2 report parameters set the same actual parameter? For example, the user should either be able to type in an ID, or select it from a dropdown list - for the query to then take that id and run the proc for that id.

  • jquery autocomplete

    - by richzilla
    Does anyone know if theres a jquery autocomplete library that works similar to the one here: http://www.thetrainline.com (try and select a station to see what i mean) The one on here is a prototype library. Basically all the ones ive found will only match characters if they appear at the beginning of a string, for example, if i typed 'ear' it would not match the word 'hear'. However this one seems to do that. If anyone has any ideas id be very grateful.

    I have a datatable. I need to fetch a certain column value based on the user input. For example, lets say the datatable has two columns CountryID and CountryName. I need to find CountryID in the datatable based on the user input country name. I could just open a connection with DB and run the query select countryID from Country where countryName = @userinput. Is there anyway i could do this on the datatable.

    - by sunpech
    I'm new to Android development and I'm currently going through some tutorials. When I setup a new Android Project in Eclipse, and select Windows - Android SDK and AVD Manager, in Virtual Devices, the list of existing Android Virtual Devices is empty. Is it supposed to be? From the pictures in the tutorial, it's pre-populated. Can I download these AVDs from somewhere, am I missing something here? Also, I'm developing this on my Macbook Pro.

  • id vs class selection benchmark

    - by zaf
    Has anybody bench marked selecting elements with id's and class's from CSS and javascript? It would make sense that an element with an id is faster to select than if it had a class even if it was the only element with that class. Do I really need to be concerned?

  • Rewrite SQL Fulltext Function to return Table only

    - by Alex
    I have a MS SQL Fulltext Function like this: (...) RETURNS TABLE AS RETURN SELECT * FROM fishes INNER JOIN CONTAINSTABLE(fishes, *, @keywords, @limit) AS KEY_TBL ON fishes.id = KEY_TBL.[KEY] When I use this function in LINQ, it generates a special return type which includes all fields of my "fishes" table, plus Key and Rank. How could I rewrite above query, or change something in LINQ, to omit Key and Rank and just return my "fishes" results (and to have the fulltext search result objects be of type Fish, which is what I really care about, so I don't have to cast)?

  • Sanity Check: change event not firing first time using keyboard

    - by macca1
    I've done a good amount of research on this and found a bunch of reported problems and solutions but the general consensus seems that all change problems in IE6 were fixed in jQuery 1.4.2. I'm having an issue where a change event is not firing in jQuery 1.4.2, but it did fire successfully in jQuery 1.3.2. This is in IE6. I'm about to submit a bug for this, but for my sanity I wanted to post it here first to see if there's something dumb I'm missing. I don't understand why this is working this way... <HTML> <HEAD> <TITLE>jQuery 1.4.2 Problem </TITLE> <script src="jquery-1.4.2.min.js" type="text/javascript"></script> <script> $(document).ready( function() { $("#firstBox").change(function() { alert("CHANGE"); }); // ONLOAD of document autofocus into the first element... $("form").find(":input:visible:first").focus() }); </script> </HEAD> <BODY> <form> <select id="firstBox"> <option value="" selected="selected">--</option> <option value="1">One</option> <option value="2">Two</option> </select> <br><br> <input size="10" id="secondBox"> </form> </BODY> </HTML> Simple enough, right? Onload of the page, give the first element focus. Onchange of the first element, alert. If you use the mouse, it works as expected. The page loads, the focus is in the drop down, you change the option, you get the alert. The problem is if you use the keyboard. The page loads, the focus is in the drop down, you press the down arrow. The option changes. Tab off the field, no alert. Weird. To make it even weirder, if you tab back into the field and change it again (all using the keyboard), the change event DOES fire after tab out this time. Any ideas?
