• SQL Server - Searching string with international characters using LIKE clause

  - by Nikhil

  Hi, I have a field 'Description' which can have product descriptions with any unicode characters. If I search for a description which contains an international character, with a LIKE condition (word searched with does not have the international character) I get the following results: Ex: GEWÜRZTRAMINER is one of the descriptions. When I do: Select * from table where Description LIKE '%GEWURZTRAMINER%', it retrieves the entry. When I do: Select * from table where Description LIKE '%GEWURZ%', the entry is not retrieved. (Note: the search condition does not include the Ü but has a U) Is there a way around this so that I can retrieve with '%GEWURZ%' as well? SQl Server 2008

• Cannot running next process when a variable save no value

  - by bruine

  First, I wanna compare between 2 tables tb_wrapper and tb_summary to get the data in the tb_wrapper that doesn't exist in the tb_summary then save in $link. If I don't get the same data, I want to print the result $link. When I don't get the not same data, I want it to go to another process. Here's the code : $q2 = mysql_query(" SELECT a.doc_url FROM tb_wrapper a LEFT JOIN tb_summary b ON a.doc_name = b.doc_summ WHERE b.doc_summ IS NULL"); while ($row = mysql_fetch_array($q2)){ $link = $row['doc_url']; if (!$link){ include 'next_process.php'; } else { print_r($link); } } it doesn't work. When I don't get the not same data or $link not save a value. table : CREATE TABLE tb1 (`id` int, `doc_name` varchar(100), `doc_url` varchar(50)) } CREATE TABLE tb2 (`id` int, `doc_summ` varchar(100)) }

• Need help in filtering records based on radius value in solr

  - by kshama

  Hi, I am using solr with Lucene spatial 2.9.1 as per http://www.ibm.com/developerworks/java/library/j-spatial/ I want to write a query, that will retrieve records within a given radius using hsin function, and using cartesian tiers as filters. So i wrote query like this http://localhost:8983/solr/select/?q=body:engineering colleges^0 AND _val_:"recip(hsin(0.227486,1.354193 , lat_rad, lng_rad, 4), 1, 1, 0)"^100 &&fq={!tier x=13.033993 y=77.589569 radians=false dist=4 prefix=tier_ unit=m} My records include many US records and few Indian records. For US records filtering based on radius is working fine. But for Indian records its not varying even if i change the radius . So can any one tell me if anything is wrong with the query or is there any configuration issues related to solr in order to make this work, or since record density is very less for Indian records filtering is not happening properly.Am not able to figure it out. Thanks in advance.

  - by Werner

  Hi, I am working on some project my boss sent to me. After unzipping, this is the structure of the files: executable_file config.mk doc include lib Makefile sources I have only worked with "usual" Makefile projects.

I need to modify it, so it compiles in another hardware, so I do not know where I sohuld work on. Thanks

• using ajax url to call function

  - by Steven Vanerp

  Hopefully I can ask this correctly cuz I know what I want it to do but can't seem to find any answers from searching. I have a func.php page where I have all my functions and I want ajax to use one function from that page. func.php function toptable() { echo"something happens in here"; } index.php <?php include 'func.php'; ?> <script type="text/javascript"> function check_username() { uname=document.getElementById("username").value; var params = "user_id="+uname; var url = "topoftable()"; $.ajax({ type: 'POST', url: url, dataType: 'html', data: params, beforeSend: function() { document.getElementById("right").innerHTML= 'checking' ; }, complete: function() { }, success: function(html) { document.getElementById("right").innerHTML= html ; } }); } </script> Make sense?

• Programmatically find maximum static array size in C++

  - by GuyGreer

  I am curious whether it is possible to determine the maximum size that an array can have in C++. #include <iostream> using namespace std; #define MAX 2000000 int main() { long array[MAX]; cout << "Message" << endl; return 0; } This compiles just fine, but then segfaults as soon as I run it (even though array isn't actually referenced). I know it's the array size too because if I change it to 1000000 it runs just fine. So, is there some define somewhere or some way of having #define MAX MAX_ALLOWED_ARRAY_SIZE_FOR_MY_MACHINE_DEFINED_SOMEWHERE_FOR_ME? I don't actually need this for anything, this question is for curiosity's sake.

• Multiple connections to a MySQL database in a single PHP script.

  - by st3

  There are multiple times in one page where I need to connect and subsequently query a MySQL database, yet my code won't let me. I think it might be something to do with how my files are nested but it makes no sense. I am opening the SQL connection in the header file. The top of the offending page looks like the following: <?php $page_title = 'Dashboard'; include('templates/header.inc'); // includes a 'require_once('mysqli_connect.php') and a small query to the database; require_once('includes/functions.php'); require_once('includes/dashboard_sql.php'); // Contains functions which connect to database (which are failing.) ?> I get the PHP error Notice: Undefined variable: dbc in /Library/WebServer/Documents/pediatory_site/includes/dashboard_sql.php Where $dbc is the database connection defined in mysqli_connect.php. If anyone could help me out that would be great.

• Why does this C program compile?

  - by AdmiralJonB

  I've just come across someone's C code that I'm confused as to why it is compiling. There are two points I don't understand. First, the function prototype has no parameters compared to the actual function definition. Secondly, the parameter in the function definition doesn't have an type. #include <stdio.h> int func(); int func(param) { return param; } int main() { int bla = func(10); printf("%d",bla); } Could someone please explain to me why this works? I've tested it in a couple of compilers and it works fine.

• Has anyone ever had OpenCV to work with Python on MacOS?

  - by ?????

  I've been trying on and off for the past 6 months to get OpenCV to work with Python on MacOS. Every time there's a new release, I try again and fail. I've tried both 64-bit and 32-bit, and both the xcode gcc and gcc installed via macports. I just spend the past two days on it, hopeful that the latest OpenCV release, that appears to include Python support directly would work. It doesn't. I've also tried and failed to use this: http://code.google.com/p/pyopencv/ I've been using OpenCV with C++ or Microsoft C++/CLI for the past few years, but I'd love to use it with Python on a Mac because that is my primary development environment. I'd love to hear from anyone who's actually done this.

• Rails activerecord includes. How to access the included columns?

  - by Lee Quarella

  I my User has_many :event_patrons and EventPatron belongs_to :user. I would like to slap together the user with one specific event patron with something like this sql statement: SELECT * FROM `users` INNER JOIN `event_patrons` ON `event_patrons`.`user_id` = `users`.`id` WHERE `event_patrons`.`event_id` = 1 So in rails I tried this: User.all(:joins => :event_patrons, :condidions => {:event_patrons => {:event_id => 1}}) But that gives me SELECT users.* instead of SELECT *: SELECT `users`* FROM `users` INNER JOIN `event_patrons` ON `event_patrons`.`user_id` = `users`.`id` WHERE `event_patrons`.`event_id` = 1 I then tried to switch the :joins with :include and got a whole jumbled mess that still returned me only the columns in User and none from EventPatron. What am I missing?

• 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.

• .resx file data inaccessible in Visual C#

  - by dsp_099

  What I'm trying to do: include some files along with the executable to extract them later. I have two projects, both with a Resource1.resx file (and some resources included from disk). In one project, I can use File.WriteAllBytes(path, Resource1.Image); to dump the resource to disk. In another, Resource1 is does not exist. I've done this before but all I can find is information about localizations (?) when I search MSDN for how to work with Resources.

• Django: Site-Wide URL Prefix

  - by Tom

  I've built a Django site that will live at the root when it's live. Right now it's functioning perfectly at the IP address. For testing purposes, the client has pointed a proxy url at it, but the url has /folder/path in it, so none of the URL patterns match. I put (/folder/path)? into all the url patterns so they now respond, but all of the links are broken because I'm using the {% url %} tag and while the url patterns will match the optional path, they don't include it in that tag. Clearly I can just hard-code /folder/path into all of my urls (well, into all of the url includes) until testing is complete, but is there a better way to do this?

• WCF and a developer key like Google map API. What exactly am I looking for?

  - by Scott

  I want to allow access to a WCF service to only those requests that contain a developer key. This is similiar to how the Google Maps API works. Register for a developer key and include that key in your requests. Anyone can get a key. How you get a key is undecided but is being discussed. For now, we'll email you a key. The service is up and running so I will be adding this on. I just need to know what I'm looking for so I can figure out what I need to do. Makes sense, right?!?! What is this scheme called? What should I search for? Any suggested links / books / whitepapers?

• C++/CLI Missing MSVCR90.DLL

  - by Mitch

  I have a c++/cli dll that I load at runtime and which works great in debug mode. If I try and load the dll in release mode it fails to load stating that one or more dependencies are missing. If I run depends against it I am missing MSVCR90.DLL from MSVCM90.DLL. If I check the debug version of the dll it also has the missing dependency, but against the debug (D) version. I have made sure debug/release embed the manifest file. I read something about there being issues with the app loading the dll being build as Any CPU and the dll being built as x86, but I don't see how to set them both to x86. I am using VS2010. Anyway, I've been messing around for a while now and have no idea what is wrong. I'm sure someone out there knows what is going on. Let me know if I need to include additional info.

• Occasional conversion error using SUM function

  - by user153777

  My app uses sql2000 and a select statement it uses will sometimes fail. Once a week or so the select returns the error 'Error Converting data type varchar to numeric' SQL: sum(case when ISNULL(form_prsn_id, -1) = irpd_prsn_id then convert(dec(11,2), case when valu_value = '' then '0' else isnull (valu_value,'0') end)* case when fmdt_deduction_flag = 'Y' then -1 else 1 end else 0 end) as client_sum The valu_value field is a varchar and stores some numeric and some varchar. But including my join and where clause filter it will always select numeric or empty string. When it is failing I can remove the SUM, see the data and know that its numeric. So why would the SUM function sometimes (say 5% of time) fail on data that is numeric. I wonder if SQL somehow "looks ahead" to ensure it could convert to decimal on more than just the rows returned without the sum. Note I have discovered a fix where I include ( where isNumeric(valu_value) = 1 ) Thanks

• std::make_shared as a default argument does not compile

  - by Mark Bryant

  In Visual C++ (2008 and 2010), the following code does not compile with the following error: #include <memory> void Foo( std::shared_ptr< int > test = ::std::make_shared< int >( 5 ) ) { } class P { void Foo( std::shared_ptr< int > test = ::std::make_shared< int >( 5 ) ) { } }; error C2039: 'make_shared' : is not a member of '`global namespace'' error C3861: 'make_shared': identifier not found It is complaining about the definition of P::Foo() not ::Foo(). Does anybody know why it is valid for Foo() to have a default argument with std::make_shared but not P::Foo()?

• rake tast can't access rails.cache

  - by mark

  Hi I want to call a rake task from a cron job that stores remote weather data in the rails cache. However, I must be doing something pretty wrong here because I cannot find any solution through countless fruitless searches. Say I define and call this task namespace :weather do desc "Store weather from remote source to cache" task :cache do Rails.cache.write('weather_data', Date.today) end end I get the error Anonymous modules have no name to be referenced by Which leads me to believe the rails cache isn't available. Outputting Rails.class from the rake file gives me Module but Rails.cache.class again returns the above error. Do I need to include something here? Am I just hopeless at internet? :) Thanks in advance.

• SQL Server float datatype

  - by Martin Smith

  The documentation for SQL Server Float says Approximate-number data types for use with floating point numeric data. Floating point data is approximate; therefore, not all values in the data type range can be represented exactly. Which is what I expected it to say. If that is the case though why does the following return 'Yes' in SQL Server DECLARE @D float DECLARE @E float set @D = 0.1 set @E = 0.5 IF ((@D + @D + @D + @D +@D) = @E) BEGIN PRINT 'YES' END ELSE BEGIN PRINT 'NO' END but the equivalent C++ program returns "No"? #include <iostream> using namespace std; int main() { float d = 0.1F; float e = 0.5F; if((d+d+d+d+d) == e) { cout << "Yes"; } else { cout << "No"; } }
