  • Use where condition with unjoined table

    - by Dragos D
    I have the following problem: I am trying to retreive a sum value based on one condition. Problem is that I can't join the conditional value since my tables aren't joined. Here is my syntax: SELECT SUM(value) FROM value v join day d on v.day_id = d.day_id join budget b on d.budget_id = b.budget_id join unit u on v.unit_id = u.unit_id where #output.class = (SELECT distinct s.class FROM sale s where s.id = #output.sale_id) AND u.unit_name in ('electronics') With this sybtax I get no error but neither values. Can you please tell me where I do wrong?

  • Grab triangles within a lower triangle

    - by Tyler Rinker
    I have the need to grab all the thee element triangles that make up the lower triangle of a symmetric matrix. I can not think of how to grab all these pieces in the order of far left column working down and then next column to the right and so on. I know that the numbe rof mini triangles inside of the lower triangle is: n = x(x - 1)/2 where: x = nrow(mats[[i]]) Here I've created three matrices with letters (it's easier for me to conceptualize this way) and the elements in the order I'm looking for: FUN <- function(n) { matrix(LETTERS[1:(n*n)], n) } mats <- lapply(3:5, FUN) So this is the output I'd like to get (I put it in code rather than output format) for each of the matrices created above: list(c("B", "C", "F")) list(c("B", "C", "G"), c("C", "D", "H"), c("G", "H", "L")) list(c("B", "C", "H"), c("C", "D", "I"), c("D", "E", "J"), c("H", "I", "N"), c("I", "J", "O"), c("N", "O", "T")) How can I do this task in the fastest manner possible while staying in base R? Not sure if this visual of what I'm after is helpful but it may be:

  • Update options to jQuery slider via form

    - by Coughlin
    I have a jQuery Slider, and I am trying to make it more dynamic by adding three input fields: min max step I want to take those fields and then onblur update my slider options. I read that you can set options like this: $('.selector').slider('option', 'max', 7); And do the same for min,step, etc along with the other options. I tried playing with it yesterday, but I'm not sure how to get it to update. I am using a form with no submit button, so just change on blur. I know I would get the .val() of the input and set it to a variable then would it be: $('.selector').slider('option', 'max', var_here); Any thoughts?

  • transferring subversion changes between linux and windows

    - by andreas buykx
    Hi all, What is the best way to transfer changes that include new and deleted directories and/or new and deleted (actually moved) files in those directories from a subversion repository on linux to windows? I do my developments on linux using a subversion repository, but I have to test my changes on windows as well. My windows machine has a tortoisesvn repository which I tried to patch with a svn diff output. This failed miserably since my patch contains a renamed (i.e. deleted and added under a different name) directory, a new directory and the files in there. Do I do things wrong by just applying the svn diff output as a patch in tortoisesvn? For now I think that my best option is to have the windows tree on the same svn version as the linux tree and just copy the entire changed directory over the existing directory. Would that work?

  • reading html from an inputstream java

    - by randeel wimalagunarathne
    hello everyone, I am reading a html file using an inputstream from a java servlet. But the contents of the original and the read one are in a different format although when displayed in a web browser they are the same. These are the two links for the html files after reading output http://www.fileflyer.com/view/gQREGAe orginal output http://www.fileflyer.com/view/mWXHVAE Is there a way to get the original html when reading? why is this happening? my java code is as follows; InputStreamReader isr = new InputStreamReader(inputStream); BufferedReader br = new BufferedReader(isr); String line = null; while ( (line = br.readLine()) != null) { System.out.println(line); } Any help would be greatly appreciated!! Thank you, rana.

  • Is this a good way to identify the type of a javascript object?

    - by FK82
    Apparently neither instanceof nor typeof deliver in terms of correctly identifying the type of every javascript object. I have come up with this function and I'm looking for some feedback: function getType() { var input = arguments[0] ; var types = ["String","Array","Object","Function","HTML"] ; //!! of the top of my head for(var n=0; n < types.length; n++) { if( input.constructor.toString().indexOf( types[n] ) != -1) { document.write( types[n] ) ; } } } Thanks for reading!

  • Help using Lisp debugger

    - by Joel
    I'm trying understand how to interpret the output of, and use, the Lisp debugger. I've got a pretty simple Backtrace for the evaluation of my function, but I cann't seem to work out how to use it to find out in which Lisp 'form' in my function the exception occurred. I'd appreciate any clues as to what I should be doing, to find the source of the error. I've attached a screen shot (if it's too small to read I can re-post it in parts), with the debug output, the function and the repl (please ignore my very wrong function, I'm just interested in learning how to use the debugger properly). In addition, I hit 'v' on the first frame to go to the source, but this resulted in the error at the bottom of the screen.

  • Looping through array in PHP to post several multipart form-data

    - by Léon Pelletier
    I'm trying in an asp web application to code a function that would loop through a list of files in a multiple upload form and send them one by one. Is this something that can be done in ASP? Because I've read some posts about how to attach several files together, but saw nothing about looping through the files. I can easily imagine it in C# via HttpWebRequest or with socket, but in php, I guess there are already function designed to handle it? // This is false/pseudo-code :) for (int index = 0; index < number_of_files; index++) { postfile(file[index]); } And in each iteration, it should send a multipart form-data POST. postfile(TheFileInfos) should make a POST like it: POST /afs.aspx?fn=upload HTTP/1.1 [Header stuff] Content-Type: multipart/form-data; boundary=----------Ef1Ef1cH2Ij5GI3ae0gL6KM7GI3GI3 [Header stuff] ------------Ef1Ef1cH2Ij5GI3ae0gL6KM7GI3GI3 Content-Disposition: form-data; name="Filename" myimage1.png ------------Ef1Ef1cH2Ij5GI3ae0gL6KM7GI3GI3 Content-Disposition: form-data; name="fileid" 58e21ede4ead43a5201206101806420000007667212251 ------------Ef1Ef1cH2Ij5GI3ae0gL6KM7GI3GI3 Content-Disposition: form-data; name="Filedata"; filename="myimage1.png" Content-Type: application/octet-stream [Octet Stream] [Edit] I'll try it: <html> <head> <title>Untitled Document</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </head> <body> <form name="form1" enctype="multipart/form-data" method="post" action="processFiles.php"> <p> <? // start of dynamic form $uploadNeed = $_POST['uploadNeed']; for($x=0;$x<$uploadNeed;$x++){ ?> <input name="uploadFile<? echo $x;?>" type="file" id="uploadFile<? echo $x;?>"> </p> <? // end of for loop } ?> <p><input name="uploadNeed" type="hidden" value="<? echo $uploadNeed;?>"> <input type="submit" name="Submit" value="Submit"> </p> </form> </body> </html>

  • How to use files/streams as source/sink in PulseAudio

    - by Nilesh
    I'm a PulseAudio noob, and I'm not sure if I'm even using the correct terminology. I've seen that PulseAudio can perform echo cancellation, but it needs a source and a sink to filter from, and a new source and sink. I can provide my mic and my audio-out as the source and sink, right? Now, here's my situation: I have two video streams, say, rtmp streams, or consider two flv files, say at any given moment, stream X is the input stream that's coming from another computer's webcam+mic and stream Y is the output stream that I'm sending, (and it's coming from my computer's webcam+mic). Question: Back to the first paragraph - here's the thing, I don't want to use my mic and my audio-out, instead, I want to use these two "input" and "output" streams as my source and sink so to speak (of course, I'll use xuggler maybe, to extract just the audio from X and Y). It may be a strange question, and I have my reasons for doing this strange this - I need to experiment and verify the results to see.

  • Is there a cap on the number of modules WinDbg can see?

    - by Bethor
    Does anyone know if there is a cap on the number of DLLs WinDbg can see ? I believe Visual Studio was once capped at 500 but I can't find a source for this claim outside of some second hand accounts at work. I'm trying to debug a hairy scenario and WinDbg's stack trace is incomplete. According to Process Explorer, the module I'm interested in is loaded but it doesn't show up in the output of 'lm' in WinDbg. Suspiciously, said output is exactly 500 modules long, even though I know there are many more than that loaded, leading me to believe WinDbg isn't seeing DLLs beyond the first 500. Can anyone confirm ? Or suggest some other reason why a loaded module might not show up in 'lm' ?

  • MapReduce results seem limited to 100?

    - by user1813867
    I'm playing around with Map Reduce in MongoDB and python and I've run into a strange limitation. I'm just trying to count the number of "book" records. It works when there are less than 100 records but when it goes over 100 records the count resets for some reason. Here is my MR code and some sample outputs: var M = function () { book = this.book; emit(book, {count : 1}); } var R = function (key, values) { var sum = 0; values.forEach(function(x) { sum += 1; }); var result = { count : sum }; return result; } MR output when record count is 99: {u'_id': u'superiors', u'value': {u'count': 99}} MR output when record count is 101: {u'_id': u'superiors', u'value': {u'count': 2.0}} Any ideas?

Would be useful to have a plugin that could recursively go trough the DOM-tree.

  • Use LINQ to SQL results inside SQL Server stored procedure

    - by ifwdev
    Note: I'm not trying to call a SQL Server stored proc using a L2SQL datacontext. I use LINQPad for some fairly complex "reporting" that takes L2SQL output saved to an Array and is processed further. For example, it's usually much easier to do multiple levels of grouping with LINQ to Objects instead of trying to optimize a T-SQL query to run in a reasonable amount of time. What would be the easiest way to take the end result of one of these "applications" and use that in a SQL Server 2008 stored proc? The idea is to use the data for a Reporting Services Report, rather than copying and pasting into Excel (manual labor). The reports need to be accessible on the report server (not using the Report Server control in an application). I could output CSV and read that somehow via command line exec, but that seems like a hack. Thanks for your help.

  • php connecting to mysql server(localhost) very slow

    - by Ahmad
    actually its little complicated: summary: the connection to DB is very slow. the page rendering takes around 10 seconds but the last statement on the page is an echo and i can see its output while the page is loading in firefox (IE is same). in google chrome the output becomes visible only when the loading finishes. loading time is approximately the same across browsers. on debugging i found out that its the DB connectivity that is creating problem. the DB was on another machine. to debug further. i deployed the DB on my local machine .. so now the DB connection is at 127.0.0.1 but the connectivity still takes long time. this means that the issue is with APACHE/PHP and not with mysql. but then i deployed my code on another machine which connects to DB remotely.and everything seems fine. basically the application uses couple of mod_rewrite.. but i removed all the .htaccess files and the slow connectivity issue remains.. i installed another APACHE on my machine and used default settings. the connection was still very slow. i added following statements to measure the execution time $stime = microtime(); $stime = explode(" ",$stime); $stime = $stime[1] + $stime[0]; // my code -- it involves connection to DB $mtime = microtime(); $mtime = explode(" ",$mtime); $mtime = $mtime[1] + $mtime[0]; $totaltime = ($mtime - $stime); echo $totaltime; the output is 0.0631899833679 but firebug Net panel shows total loading time of 10-11 seconds. same is the case with google chrome i tried to turn off windows firewall.. connectivity is still slow and i just can't quite find the reason.. i've tried multiple DB servers.. multiple apaches.. nothing seems to be working.. any idea of what might be the problem?

  • VB.net Enter Key

    - by Andrew
    I was given the following pseudo code in order to get the form that has focus and only allow the form I want to be submitted: <script> var currentForm = document.forms[0];</script> <form ...><input onfocus="currentForm = this.form;"/></form> <form ...><input onfocus="currentForm = this.form;"/></form> function globalKeyPressed(event) { if (event.keyCode == ENTER) { // This is pseudo-code, check how to really do it currentForm.submit(); } } How would I do this for VB.net because VB.net doesn't accept System.Windows.Forms.KeyPressEventArgs. I also wanted to add that I can't have multiple forms on my website as it disrupts the loginview. So my 2 seperate 'forms' are really just a loginview and then an asp:textbox and asp:button by themselves without a form.
