  • Eliminate duplicates in SQL query

    - by ewdef
    i have a table with 6 fields. the columns are ID, new_id price,title,Img,Active. I have datawhich is duplicated for the price column. When I do a select i want to show only distinct rows where new_id is not the same. e.g.- ID New_ID Price Title Img Active 1 1 20.00 PA-1 0X4... 1 2 1 10.00 PA-10 0X4... 1 3 3 20.00 PA-11 0X4... 1 4 4 30.00 PA-5 0X4... 1 5 9 20.00 PA-99A 0X4... 1 6 3 50.00 PA-55 0X4... 1 When the select statement runs, only rows with ID (1,4,9,6) should show. Reason being the new_ID with the higher price should show up. How can i do this?

  • comparing multidimensional array

    - by John K
    Hello everyone, I have the following array: Array ( [0] => Array ( [0] => 87 [1] => 55 [2] => 85 [3] => 86 ) [1] => Array ( [0] => 58 [1] => 84 ) [2] => Array ( [0] => 58 ) ) This array above is an example. The actual array is of variable size, but structured like this. Basically, I'd like to run array_intersect on each second level array and grab the value (number) that is common between them. In this case, it would be 58. I'm not quite sure where to start on this. Any advice?

  • MySQL Join Comma Separated Field

    - by neeraj
    I have two tables. First Table is a batch table that contain comma separated student id in field "batch" batch -------------- id batch -------------- 1 1,2 2 3,4 Second Table is marks marks ---------------------- id studentid subject marks 1 1 English 50 2 2 English 40 3 3 English 70 4 1 Math 65 5 4 English 66 6 5 English 75 7 2 Math 55 How we can find those students of first batch id =1 who have scored more than 45 marks in English without using sub query. Problem i found to get this done using a single query is that we can not use IN as an association operator in JOIN statement What changes are required in below query to make it work? SELECT * FROM batch INNER JOIN marks ON marks.studentid IN(batch.batch) where batch.id = 1

  • AppEngine GeoPt Data Upload

    - by Eric Landry
    I'm writing a GAE app in Java and only using Python for the data upload. I'm trying to import a CSV file that looks like this: POSTAL_CODE_ID,PostalCode,City,Province,ProvinceCode,CityType,Latitude,Longitude 1,A0E2Z0,Monkstown,Newfoundland,NL,D,47.150300000000001,-55.299500000000002 I was able to import this file in my datastore if I import Latitude and Longitude as floats, but I'm having trouble figuring out how to import lat and lng as a GeoPt. Here is my loader.py file: import datetime from google.appengine.ext import db from google.appengine.tools import bulkloader class PostalCode(db.Model): id = db.IntegerProperty() postal_code = db.PostalAddressProperty() city = db.StringProperty() province = db.StringProperty() province_code = db.StringProperty() city_type = db.StringProperty() lat = db.FloatProperty() lng = db.FloatProperty() class PostalCodeLoader(bulkloader.Loader): def __init__(self): bulkloader.Loader.__init__(self, 'PostalCode', [('id', int), ('postal_code', str), ('city', str), ('province', str), ('province_code', str), ('city_type', str), ('lat', float), ('lng', float) ]) loaders = [PostalCodeLoader] I think that the two db.FloatProperty() lines should be replaced with a db.GeoPtProperty(), but that's where my trail ends. I'm very new to Python so any help would be greatly appreciated.

  • Bind event to shape on canvas

    How can I bind an event to a shape drawn on a canvas?

  • What's a good way to set up a development environment on OS X for ruby, rails, and git?

    - by Ein2015
    I'm going to start development on a web app using ruby, rails, probably either postgres or mysql, and most likely apache. I'll be using a git repository with the master repo on another server. I've searched through stackoverflow and done some Googling... so here's what I have so far... What are your opinions on what's described on this page?: http://robots.thoughtbot.com/post/159805668/2009-rubyists-guide-to-a-mac-os-x-development What about this one?: http://www.buildingwebapps.com/articles/79197-setting-up-rails-on-leopard-mac I don't need helping finding an editor, there's plenty out there (TextMate, TextWrangler, MacVim), but I do need help to make sure I'm setting things up correctly to code, build, and run the web app from my mac. Here's a specific set of scenarios I could use some help on: Testing various versions of rails and/or ruby. Testing performance, vulnerabilities, monitoring queries, etc. Testing different versions of gems. Working on other projects on this same machine.

  • save jQuerry changes to css file on server

    - by KrisRogo
    I'm developing a system that allows for changing some of the css parameters without accessing the code. To achieve that I have jQuerry objects like sliders and draggers which influence how the site looks user side, eg. $("#MainContent").css("width", "55%");. Now I need a way to append those changes to a .css file on the server. Let me clarify that this is sort of a CMS system, and only administrator of the system would have this option, not the visitors of user-end site. I realise that .css is one for all users. Ideal solution would connect to the server every time user makes a change, and replace only one line of css code. But I have no idea how to do it efficiently or if it at all possible.

  • Linked List. Insert integers in order

    - by user69514
    I have a linked list of integers. When I insert a new Node I need to insert it not at the end, but in oder... i.e. 2, 4, 5, 8, 11, 12, 33, 55, 58, 102, etc. I don't think I am inserting it in the correct position. Do see what Im doing wrong? Node newNode = new Node(someInt); Node current = head; for(int i=0; i<count; i++){ if(current == tail && tail.data < someInt){ tail.next = newNode; } if(current.data < someInt && current.next.data >= someInt){ newNode.next = current.next; current.next = newNode; } }

  • How can I get values from one table to another via similar values?

    - by Andrija
    I have a table called excel that has 3 columns, name, id, and full_name. The name part is the only one I have and I need to fill id and full_name. The other table that contains the data is called tim_pismena and has 2 columns that I need, id and pismeno_name (the actual names are not important, but i'm writing them just for clarity). In pseudooracle code :) the select that gets me the values from the second table would be done something like this: SELECT tp.id, tp.pismeno_name FROM tim_pismena tp WHERE upper(tp.naziv_pismena) LIKE IN upper('%(SELECT ime as FROM excel)%') and when used with an insert, the end result should be something like name id full_name Happy Joe 55 Very fun place Happy Joe, isn't it?

  • Can anyone tell why Wordpress is adding this p tag?

    - by Elliott Samuel Lemberger
    Here's the page: http://www.gammagoochee.com/media/ WP is adding a p tag on line 55 between the end of my header and the beginning of my post content. I am using Raw HTML Pro, and the post starts with content surrounded by [raw] tags. There is no content between the last tag in my header, and the beginning of my post. This doesn't happen on my other site pages, and the only difference is that this page is using a template, but the template is the same in this part of the page. All the template does differently than the other site pages is add a sidebar. Anyone have any ideas whatsoever why WP is adding this p tag, and/or how I can prevent it? Thanks so much!

  • Rails botches the SQL on a complex save

    - by Dan B
    Hi, I am doing something seemingly pretty easy, but Rails is messing up the SQL. I could just execute my own SQL, but the framework should be able to handle this. Here is the save I am trying to perform: w = WhipSenVote.find(:first, :conditions => ["whip_bill_id = ? AND whip_sen_id = ?", bill_id, k]) w.votes_no = w.votes_no - 1 w.save My generated SQL looks like this: SELECT * FROM "whip_sen_votes" WHERE (whip_bill_id = E'1' AND whip_sen_id = 7) LIMIT 1 And then: UPDATE "whip_sen_votes" SET "votes_yes" = 14, "updated_at" = '2009-11-13 19:55:54.807000' WHERE "id" = 15 The first select statement is correct, but as you can see, the Update SQL statement is pretty wrong, though the votes_yes value is correct. Any ideas? Thanks!

  • Multiple levels of 'collection.defaultdict' in Python

    - by Morlock
    Thanks to some great folks on SO, I discovered the possibilities offered by collections.defaultdict, notably in readability and speed. I have put them to use with success. Now I would like to implement three levels of dictionaries, the two top ones being defaultdict and the lowest one being int. I don't find the appropriate way to do this. Here is my attempt: from collections import defaultdict d = defaultdict(defaultdict) a = [("key1", {"a1":22, "a2":33}), ("key2", {"a1":32, "a2":55}), ("key3", {"a1":43, "a2":44})] for i in a: d[i[0]] = i[1] Now this works, but the following, which is the desired behavior, doesn't: d["key4"]["a1"] + 1 I suspect that I should have declared somewhere that the second level defaultdict is of type int, but I didn't find where or how to do so. The reason I am using defaultdict in the first place is to avoid having to initialize the dictionary for each new key. Any more elegant suggestion? Thanks pythoneers!

  • php - How do I get rid of this strange "empty delimiter" message

    - by Steven
    I have some code that uses the stristr function to extract data I need. It works, in that it gives me the results I'm looking for. BUT (you knew there was a but), it gives me this error message for every iteration of the loop: Warning: stristr() [function.stristr]: Empty delimiter in ... line 55 Like I said, the code works apart from this error. Can anyone suggest how i could amend this code to get rid of the message? Thanks in advance $data = stristr("$text", "$key"); $result = string_limit_words($data,2); print "$result<BR>";

  • Xcode OpenGL Build Error (header file not found)

    - by Strix Nebulosa
    When building my Objective-C project (for Mac OS 10.9, Xcode 5.11), I get the error message Lexical or Preprocessor Issue 'OpenGL/OpenGL.h' file not found. The error is caused by the include section of the file CVDisplayLink.h where the above named file is included. CVDisplayLink.h belongs to the framework CoreVideo. Now there are two strange points related to that issue: The error appeared after I tried to test some basic OpenGL features using the tutorial in the Mac Developer Library ( https://developer.apple.com/library/mac/documentation/GraphicsImaging/Conceptual/OpenGL-MacProgGuide/opengl_drawing/opengl_drawing.html#//apple_ref/doc/uid/TP40001987-CH404-SW8 ). I added an NSOpenGLView to my MainMenu as well as the related code given in the tutorial. Then the error message appeared. I also tried to add the OpenGL and CoreVideo frameworks to my project target, but this did not help. After some frustration, I removed the NSOpenGLView from my project, as well as all related code. Now the error Message still appeares and I have no Idea how to ged rid of it.

    - by chuck
    My coding isnt linking properly , its meant to use jquery to detect the OS and change the link accordingly , however it isn't. In my HTML page I have it linked in the header as <script src="jsquery.js" type="text/javascript"></script> which loads up my jsquery now $(document).ready(function() { if (navigator.appVersion.indexOf("Win") != -1) { // Computers runs windows $("a[href$='.pdf']").each(function() { this.href = this.href.replace("Volumes", "KP01DS0194TG"); }); } if (navigator.appVersion.indexOf("Mac") != -1) { // computer is a Mac $("a[href$='.pdf']").each(function() { this.href = this.href.replace("KP01DS0194TG", "Volumes"); }); } }); Yet on Mac's it still tries to connect to KP01DS0194TG and not to Volumes - it doesnt change it - how can I get it to recognize the OS and change it accordingly?

  • it is possible to "group by" without losing the original rows?

  • jQuery selector to target any CSS name (of multiple present) starting with a prefix?

    - by John K
    I'm considering one selection statement that would target one of many css class names in a single class attribute value based on a string prefix. For example, I want any detail- prefixed class names to get targeted from the following sample links. <a href="eg.html" class="detail-1 pinkify another"> <a href="eg.html" class="something detail-55 minded"> <a href="eg.html" class="swing narrow detail-Z"> <a href="eg.html" class="swing narrow detail-Z detail-88 detail-A"> It's reminiscent of how [class|="detail"] prefix selector works on a scalar attribute value, and also of .hasClass(className), but my question needs both concepts applied simultaneously. Note: The detail- prefix won't necessarily be the first class name of the bunch.

  • Why can I not have two SocketServers bound to two different ports in the same application?

    - by uriDium
    I am using .Net 3.5 and Windows XP not sure if any more information is needed. I have an application that creates a socket, binds to a port and starts listening. A client comes and connects and then disconnects no problem. It can then reconnect no problem. If I have to sockets each listening on a different (e.g. 50 000 and 55 000) then it will accept the connection but it will not allow a reconnect. I will post source code if needed but I am assuming that it is just something simple that I am not catching.

  • An array of structures in C...

    - by 00010000
    For the life of me I can't figure out the proper syntax for creating an array of structures in C. I tried this: struct foo { int x; int y; } foo[][] = { { { 1, 2 }, { 4, 5 }, { -1, -1 } }, { { 55, 44 } { 100, 200 }, } }; So for example foo[1][0].x == 100, foo[0][1].y == 5, etc. But GCC spits out a lot of errors. If anyone could provide the proper syntax that'd be great. EDIT: Okay, I tried this: struct foo { const char *x; int y; }; struct foo bar[2][] = { { { "A", 1 }, { "B", 2 }, { NULL, -1 }, }, { { "AA", 11 }, { "BB", 22 }, { NULL, -1 }, }, { { "ZZ", 11 }, { "YY", 22 }, { NULL, -1 }, }, { { "XX", 11 }, { "UU", 22 }, { NULL, -1 }, }, }; But GCC gives me "elements of array bar have incomplete type" and "excess elements in array initializer".

I was using: for line in map(str.split,inp): x = line[-3] y = line[-2] z = line[-1] for separating the values, but how to do in iterative way. should I do it by using Counter.
