  • choosing row (from group) with max value in a SQL Server Database

    - by sriehl
    I have a large database and am putting together a report of the data. I have aggregated and summed the data from many tables to get two tables that look like the following. id | code | value id | code | value 13 | AA | 0.5 13 | AC | 2.0 13 | AB | 1.0 14 | AB | 1.5 14 | AA | 2.0 13 | AA | 0.5 15 | AB | 0.5 15 | AB | 3.0 15 | AD | 1.5 15 | AA | 1.0 I need to get a list of id's, with the code (sumed from both tables) with the largest value. 13 | AC 14 | AA 15 | AB There are 4-6 thousand records and it is not possible to change the original tables. I'm not too worried about performance as I only need to run it a few times a year. edit: Let me see if I can explain a bit more clearly, imagine the id is the customer id, the code is who they ordered from and the value is how much they spent there. I need a list of the all the customer id's and the store that customer spent the most money at (and if they spent the same at two different stores, put a value such as 'ZZ' in for the store name).

  • JQuery Autocomplete only suggesting first row

    - by Chris McCall
    I'm doing research using JQuery's Autocomplete plugin and Google Maps' API. What I have so far is located here. I'm using Asp.net MVC to generate the list of potential address matches (limited to US addresses only) and presenting them as a pipe-delimeted list to Autocomplete, which is supposed to be .spliting them up and suggesting them to the user. The problem I'm having (besides a stubborn IE-only javascript error, which I'll break into another question), is that only the first result is suggested. This page clearly shows two results, yet typing "3118" into the textbox produces only the Galax Dr result. How can I get Automplete to produce both results?

  • Java List with Objects - find and replace (delete) entry if Object with certain attribute already ex

    - by Sophomore
    Hi there I've been working all day and I somehow can't get this probably easy task figured out - probably a lack of coffee... I have a synchronizedList where some Objects are being stored. Those objects have a field which is something like an ID. These objects carry information about a user and his current state (simplified). The point is, that I only want one object for each user. So when the state of this user changes, I'd like to remove the "old" entry and store a new one in the List. protected static class Objects{ ... long time; Object ID; ... } ... if (Objects.contains(ID)) { Objects.remove(ID); Objects.add(newObject); } else { Objects.add(newObject); } Obviously this is not the way to go but should illustrate what I'm looking for... Maybe the data structure is not the best for this purpose but any help is welcome!

  • How to delete a large cookie that causes Apache to 400

    - by jakemcgraw
    I've come across an issue where a web application has managed to create a cookie on the client, which, when submitted by the client to Apache, causes Apache to return the following: HTTP/1.1 400 Bad Request Date: Mon, 08 Mar 2010 21:21:21 GMT Server: Apache/2.2.3 (Red Hat) Content-Length: 7274 Connection: close Content-Type: text/html; charset=iso-8859-1 <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>400 Bad Request</title> </head><body> <h1>Bad Request</h1> <p>Your browser sent a request that this server could not understand.<br /> Size of a request header field exceeds server limit.<br /> <pre> Cookie: ::: A REALLY LONG COOKIE ::: </pre> </p> <hr> <address>Apache/2.2.3 (Red Hat) Server at www.foobar.com Port 80</address> </body></html> After looking into the issue, it would appear that the web application has managed to create a really long cookie, over 7000 characters. Now, don't ask me how the web application was able to do this, I was under the impression browsers were supposed to prevent this from happening. I've managed to come up with a solution to prevent the cookies from growing out of control again. The issue I'm trying to tackle is how do I reset the large cookie on the client if every time the client tries to submit a request to Apache, Apache returns a 400 client error? I've tried using the ErrorDocument directive, but it appears that Apache bails on the request before reaching any custom error handling.

  • Rotation Matrix calculates by column not by row

    - by pinnacler
    I have a class called forest and a property called fixedPositions that stores 100 points (x,y) and they are stored 250x2 (rows x columns) in MatLab. When I select 'fixedPositions', I can click scatter and it will plot the points. Now, I want to rotate the plotted points and I have a rotation matrix that will allow me to do that. The below code should work: theta = obj.heading * pi/180; apparent = [cos(theta) -sin(theta) ; sin(theta) cos(theta)] * obj.fixedPositions; But it wont. I get this error. ??? Error using == mtimes Inner matrix dimensions must agree. Error in == landmarkslandmarks.get.apparentPositions at 22 apparent = [cos(theta) -sin(theta) ; sin(theta) cos(theta)] * obj.fixedPositions; When I alter forest.fixedPositions to store the variables 2x250 instead of 250x2, the above code will work, but it wont plot. I'm going to be plotting fixedPositions constantly in a simulation, so I'd prefer to leave it as it, and make the rotation work instead. Any ideas? Also, fixed positions, is the position of the xy points as if you were looking straight ahead. i.e. heading = 0. heading is set to 45, meaning I want to rotate points clockwise 45 degrees. Here is my code: classdef landmarks properties fixedPositions %# positions in a fixed coordinate system. [x, y] heading = 45; %# direction in which the robot is facing end properties (Dependent) apparentPositions end methods function obj = landmarks(numberOfTrees) %# randomly generates numberOfTrees amount of x,y coordinates and set %the array or matrix (not sure which) to fixedPositions obj.fixedPositions = 100 * rand([numberOfTrees,2]) .* sign(rand([numberOfTrees,2]) - 0.5); end function obj = set.apparentPositions(obj,~) theta = obj.heading * pi/180; [cos(theta) -sin(theta) ; sin(theta) cos(theta)] * obj.fixedPositions; end function apparent = get.apparentPositions(obj) %# rotate obj.positions using obj.facing to generate the output theta = obj.heading * pi/180; apparent = [cos(theta) -sin(theta) ; sin(theta) cos(theta)] * obj.fixedPositions; end end end P.S. If you change one line to this: obj.fixedPositions = 100 * rand([2,numberOfTrees]) .* sign(rand([2,numberOfTrees]) - 0.5); Everything will work fine... it just wont plot.

  • How does NHibernate handle cascade="all-delete-orphan"?

    - by Johannes Rudolph
    I've been digging around the NHibernate sources a little, trying to understand how NHibernate implements removing child elements from a collection. I think I've already found the answer, but I'd ideally like this to be confirmed by someone familiar with the matter. So far I've found AbstractPersistentCollection (base class for all collection proxies) has a static helper method called GetOrphans to find orphans by comparing the current collection with a snapshot. The existence of this method suggests NHibernate tries to find all oprhaned elements and then deletes them by key. Is this correct, in terms of the generated SQL?

  • ajax-based login fails: IE6 and IE7 ajax calls delete session data (session_id however is kept)

    - by mateipavel
    This question comes after two days of testing and debugging, right after the shock I had seeing that none of the websites i build using ajax-based login work in IE<8 The most simplified scenario si this: 1. mypage.php : session_start(); $_SESSION['mytest'] = 'x'; <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"> </script> <script type="text/javascript"> function loadit() { $.post('http://www.mysite.com/myajax.php', {action: 'test'}, function(result){alert(result);}, 'html'); } </script> <a href="javascript:void(0);" onclick="loadit(); return false;">test link</a> 2. myajax.php session_start(); print_r($_SESSION); print session_id(); When I click the "test link", the ajax call is made and the result is alert()-ed: IE6: weird bullet-character (&bull;) IE7: Array( ) <session_id> IE8/FF (Expected behaviour): Array( [mytest] => 'x' ) <session_id> I would really appreciate some pointers regarding: 1. why this happens 2. how to fix it Thank you.

  • how to insert multiple rows using cakephp

    - by Paul
    In the cakePHP project I'm building, I want to insert a defined number of identical records. These will serve as placeholders records that will have additional data added later. Each record will insert the IDs taken from two belongs_to relationships as well as two other string values. What I want to do is be able to enter a value for the number of records I want created, which would equate to how many times the data is looped during save. What I don't know is: 1) how to setup a loop to handle a set number of inserts 2) how to define a form field in cakePHP that only sets the number of records to create. What I've tried is the following: function massAdd() { $inserts_required = 1; while ($inserts_required <= 10) { $this->Match->create(); $this->Match->save($this->data); echo $inserts_required++; } $brackets = $this->Match->Bracket->find('list'); $this->set(compact('brackets')); } What happens is: 1) at the top of the screen, above the doc type, the string 12345678910 is displayed, this is displayed on screen 2) a total of 11 records are created, and only the last record has the values passed in the form. I don't know why 11 records as opposed to 10 are created, and why only the last records has the entered form data? As always, your help and direction is appreciated. -Paul

  • mysql: Average over multiple columns in one row, ignoring nulls

    - by Sai Emrys
    I have a large table (of sites) with several numeric columns - say a through f. (These are site rankings from different organizations, like alexa, google, quantcast, etc. Each has a different range and format; they're straight dumps from the outside DBs.) For many of the records, one or more of these columns is null, because the outside DB doesn't have data for it. They all cover different subsets of my DB. I want column t to be their weighted average (each of a..f have static weights which I assign), ignoring null values (which can occur in any of them), except being null if they're all null. I would prefer to do this with a simple SQL calculation, rather than doing it in app code or using some huge ugly nested if block to handle every permutation of nulls. (Given that I have an increasing number of columns to average over as I add in more outside DB sources, this would be exponentially more ugly and bug-prone.) I'd use AVG but that's only for group by, and this is w/in one record. The data is semantically nullable, and I don't want to average in some "average" value in place of the nulls; I want to only be counting the columns for which data is there. Is there a good way to do this? Ideally, what I want is something like UPDATE sites SET t = AVG(a*a_weight,b*b_weight,...) where any null values are just ignored and no grouping is happening.

  • SVN Delete with wildcard?

    - by David Lively
    I'm migrating a VSS repository to SVN and inadvertently included all of the _vti_cnf, *.scc files in the first check-in. I'd like to remove these from SVN. (Not permanently, of course - just in the HEAD). The application in question is quite large, and finding and deleting these files on a folder-by-folder basis will take forever. Suggestions? There must be some obvious way to do this, but the proximity of the weekend is interfering with my higher brain functions.

  • Turn RSS into array, explode the 'description' and insert words into MySQL table one per row

    - by K.I
    I have only recently gotten into php and MySQL and I want to take an RSS feed, turn it into an array, take only the description part of the XML, explode it and insert it into a table on a MySQL base. I feel like this should be possible, but is a little over my head right now. I tried using magpie as a parser, but if possible I want to do it in simpler php code. The result I am looking for would take a description "This is a cat" and insert it into a table with two fields ID term 1 This 2 is 3 a 4 cat I've been stumped on this for a couple days. Any help would be great.
