  • Heavy Mysql operation & Time Constraints [closed]

    - by Rahul Jha
    There is a performance issue where that I have stuck with my application which is based on PHP & MySql. The application is for Data Migration where data has to be uploaded and after various processes (Cleaning from foreign characters, duplicate check, id generation) it has to be inserted into one central table and then to 5 different tables. There, an id is generated and that id has to be updated to central table. There are different sets of records and validation rules. The problem I am facing is that when I insert say(4K) rows file (containing 20 columns) it is working fine within 15 min it gets inserted everywhere. But, when I insert the same records again then at this time it is taking one hour to insert (ideally it should get inserted by marking earlier inserted data as duplicate). After going through the log file, I noticed is that there is a Mysql select statement where I am checking the duplicates and getting ID which are duplicates. Then I am calling a function inside for loop which is basically inserting records into 5 tables and updates id to central table. This Calling function is major time of whole process. P.S. The records has to be inserted record by record.. Kindly Suggest some solution.. //This is that sample code $query=mysql_query("SELECT DISTINCT p1.ID FROM table1 p1, table2 p2, table3 a WHERE p2.datatype =0 AND (p1.datatype =1 || p1.datatype=2) AND p2.ID =0 AND p1.ID = a.ID AND p1.coulmn1 = p2.column1 AND p1.coulmn2 = p2.coulmn2 AND a.coulmn3 = p2.column3"); $num=mysql_num_rows($query); for($i=0;$i<$num;$i++) { $f=mysql_result($query,$i,"ID"); //calling function RecordInsert($f); }

  • Shuffling words in a sentence in javascript (coding horror - How to improve?)

    - by Bill Zimmerman
    Hi, I'm trying to do something that is fairly simple, but my code looks terrible and I am certain there is a better way to do things in javascript. I am new to javascript, and am trying to improve my coding. This just feels very messy. All I want to do is to randomly change the order some words on a web page. In python, the code would look something like this: s = 'THis is a sentence' shuffledSentence = random.shuffle(s.split(' ')).join(' ') However, this is the monstrosity I've managed to produce in javascript //need custom sorting function because javascript doesn't have shuffle? function mySort(a,b) { return a.sortValue - b.sortValue; } function scrambleWords() { var content = $.trim($(this).contents().text()); splitContent = content.split(' '); //need to create a temporary array of objects to make sorting easier var tempArray = new Array(splitContent.length); for (var i = 0; i < splitContent.length; i++) { //create an object that can be assigned a random number for sorting var tmpObj = new Object(); tmpObj.sortValue = Math.random(); tmpObj.string = splitContent[i]; tempArray[i] = tmpObj; } tempArray.sort(mySort); //copy the strings back to the original array for (i = 0; i < splitContent.length; i++) { splitContent[i] = tempArray[i].string; } content = splitContent.join(' '); //the result $(this).text(content); } Can you help me to simplify things?

  • Why aren't these Canvases rendering?

    - by bpapa
    I'm creating a web app that allows users to enter a number of colors, by specifying RGB values. Upon submission, the user will see a canvas with a solid rectangle drawn in the color chosen. On this page, I have 7 canvases. The first one draws just fine, but none of the rest show up. The browser is Safari. Here's the relevant code: First, the script element in the header, which defines the function I use to draw to the canvas. <script language="JavaScript" TYPE="text/javascript"><!-- function drawCanvas(canvasId, red, green, blue) { var theCanvas = document.getElementById("canvas" + canvasId); var context = theCanvas.getContext("2d"); context.clearRect(0,0,100,100); context.setFillColor(red,green,blue,1.0); context.fillRect(0,0,100,100); } // --> </script> Next, the HTML source, where I have my canvas tags and some embedded Javascript to call my drawCanvas function <canvas id="canvas0" width="100" height="100"> </canvas> <script language="JavaScript" TYPE="text/javascript"><!-- drawCanvas(0,250,0,0); // --> </script> . . //more source . <canvas id="canvas1" width="100" height="100"> </canvas> <script language="JavaScript" TYPE="text/javascript"><!-- drawCanvas(1,4,250,6); // --> </script> Also provided is a screenshot. As you can see, the "red" canvas comes up just fine, but the second one, which should be green, doesn't show up at all. Any ideas?

  • Are these two functions the same?

    - by Ranhiru
    There is a function in the AES algorithm, to multiply a byte by 2 in Galois Field. This is the function given in a website private static byte gfmultby02(byte b) { if (b < 0x80) return (byte)(int)(b <<1); else return (byte)( (int)(b << 1) ^ (int)(0x1b) ); } This is the function i wrote. private static byte MulGF2(byte x) { if (x < 0x80) return (byte)(x << 1); else { return (byte)((x << 1) ^ 0x1b); } } What i need to know is, given any byte whether this will perform in the same manner. Actually I am worried about the extra conversion of to int and then again to byte. So far I have tested and it looks fine. Does the extra cast to int and then to byte make a difference?

  • Writing to the DataContext

    - by user738383
    I have a function. This function takes an IEnumerable<Customer> (Customer being an entity). What the function needs to do is tell the DataContext (which has a collection of Customers as a property) that its Customers property needs to be overwritten with this passed in IEnumerable<Customer>. I can't use assignment because DomainContext.Customers cannot be assigned to, as it is read only. I guess it's not clear what I'm asking, so I suppose I should say... how do I do that? So we have DataContext.Customers (of type System.Data.Linq.Table) which wants to be replaced with a System.Collections.Generic.IEnumerable. I can't just assign the latter to the former because DataContext's properties are read only. But there must be a way. Edit: here's an image: Further edit: Yes, this image does not feature a collection of the type 'Customer' but rather 'Connection'. It doesn't matter though, they are both created from tables within the linked SQL database. So there is a dc.Connections, a dc.Customers, a dc.Media and so on. Thanks in advance.

  • How to patch an S4 method in an R package?

    - by Richie Cotton
    If you find a bug in a package, it's usually possible to patch the problem with fixInNamespace, e.g. fixInNamespace("mean.default", "base"). For S4 methods, I'm not sure how to do it though. The method I'm looking at is in the gWidgetstcltk package. You can see the source code with getMethod(".svalue", c("gTabletcltk", "guiWidgetsToolkittcltk")) I can't find the methods with fixInNamespace. fixInNamespace(".svalue", "gWidgetstcltk") Error in get(subx, envir = ns, inherits = FALSE) : object '.svalue' not found I thought setMethod might do the trick, but setMethod(".svalue", c("gTabletcltk", "guiWidgetsToolkittcltk"), definition = function (obj, toolkit, index = NULL, drop = NULL, ...) { widget = getWidget(obj) sel <- unlist(strsplit(tclvalue(tcl(widget, "selection")), " ")) if (length(sel) == 0) { return(NA) } theChildren <- .allChildren(widget) indices <- sapply(sel, function(i) match(i, theChildren)) inds <- which(visible(obj))[indices] if (!is.null(index) && index == TRUE) { return(inds) } if (missing(drop) || is.null(drop)) drop = TRUE chosencol <- tag(obj, "chosencol") if (drop) return(obj[inds, chosencol, drop = drop]) else return(obj[inds, ]) }, where = "package:gWidgetstcltk" ) Error in setMethod(".svalue", c("gTabletcltk", "guiWidgetsToolkittcltk"), : the environment "gWidgetstcltk" is locked; cannot assign methods for function ".svalue" Any ideas?

  • Javascript not working in firefox

    - by Samuel Meddows
    Hi guys, I have a PHP form validation function that I developed in chrome and now will not work in firefox or Opera. The function checks to see if a section of the form is blank and shows and error message. If there is no error then then the form submits through document.events.submit(); CODE: function submit_events() { //Check to see if a number is entered if the corosponding textbox is checked if (document.events.dj_card.checked == true && dj_amount.value==""){ //Error Control Method //alert ('You didn\'t enetr an Amount for DJ\'s Card!'); var txt=document.getElementById("error") txt.innerHTML="<p><font color=\"#FF0000\"> You didn\'t enetr an Amount for DJ\'s Card!</font></p>"; window.document.getElementById("dj_card_label").style.color = '#FF0000'; //Reset window.document.getElementById("company_amount_label").style.color = '#000000'; window.document.getElementById("own_amount_label").style.color = '#000000'; }else{ document.events.submit(); } The document.events.submit();does work across all my browsers however the check statements do not. If the box is not ticked the form submits. If the box is ticked it does not matter whether there is data in the dj_amount.value or not. The form will not submit and no error messages are displayed. Thanks guys.

  • Passing an array of structs in C

    - by lelouch
    I'm having trouble passing an array of structs to a function in C. I've created the struct like this in main: int main() { struct Items { char code[10]; char description[30]; int stock; }; struct Items MyItems[10]; } I then access it like: MyItems[0].stock = 10; etc. I want to pass it to a function like so: ReadFile(MyItems); The function should read the array, and be able to edit it. Then I should be able to access the same array from other functions. I've tried heaps of declarations but none of them work. e.g. void ReadFile(struct Items[10]) I've had a look around for other questions, but the thing is they're all done different, with typedefs and asterisks. My teacher hasn't taught us pointers yet, so I'd like to do it with what I know. Any ideas? :S EDIT: Salvatore's answer is working after I fixed my prototype to: void ReadFile(struct Items[9]);

  • Getting all selected checkboxes values using ajax and jsp/servlets?

    - by A.S al-shammari
    Hi.. I'm developing a jsp/serlvet application. I have a page with a list of inputs as checkboxes . I want to send values of selected buttons to a servlet using ajax/jquery. In the servlet , I want to extract these values and use them . for example: The user checks some checkboxes , for example, list of messages. He/She presses Delete Link to delete selected messages. I searched and found something like this : $("#inboxDeleteSelected").click(function(){ var data = { 'checkBoxList[]' : []}; var list=$(":input:checkbox:checked"); // getting all selected checkboxes. $(list.each(function() { data['checkBoxList[]'].push($(this).val()); })); $.post("servlet?do=deleteSelected",data,function(d){ // do something here }); }); My questions: How can I send selected checkboxes values to a servlet ? How can I extract these values in the servlet ? Note: I don't use submit button to submit the selected checkboxes,Indeed I use link/anchor to send those values .

  • How do I rewrite .after( content, content )?

    - by Evan Carroll
    I've got this form working, but according to my previous question it might not be supported: it isn't in the docs either way -- but the intention is pretty obvious in the code. $(".section.warranty .warranty_checks :last").after( $('<div class="little check" />').click( function () { alert('hi') } ) , $('<span>OEM</span>') /*Notice this (a second) argument */ ); What this does is insert <div class="little check"> with a simple .click() callback, followed by a sibling of <span>OEM</span>. How else can I write this then? I'm having difficulty conjuring something working by chaining any combination of .after(), and .insertAfter()? I would expect this to work, but it doesn't: $(".section.warranty .warranty_checks :last").after( $('<div class="little check" />').click( function () { alert('hi') } ).after ( $('<span>OEM</span>') ) ); I would also expect this to work, but it doesn't: $(".section.warranty .warranty_checks :last").after( $('<span>OEM</span>').insertAfter( $('<div class="little check" />').click( function () { alert('hi') } ) ); );

  • JQuery - Check when image is loaded?

    - by JasonS
    Hi, I am having a bit of trouble working out when an image has been loaded. I have been told that the following function will work but it isn't doing anything. $("#photos img:first").load(function (){ alert("Image loaded!"); }); There are no error's in my code. Everything else in my script works great. My HTML looks like this. <div id="photos"> <img src="../sample1.jpg" style="background-color:#000033" width="1" height="1" alt="Frog!"/> <img src="../sample2.jpg" style="background-color:#999999" width="1" height="1" alt="Zooey!"/> </div> Do I have the wrong JQuery function? It should also be noted that the visibility is set to hidden. However even when visible there is no alert. Any ideas?

  • Multiple Facebook scripts?

    - by J Set
    This may be kind of a dumb question, but the script for the facebook button on the like button page is different from the script on the javascript sdk page, but similar. Did facebook just forget to update the documentation or do I need both scripts? The like button page gives: <div id="fb-root"></div> <script> (function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/en_US/all.js#xfbml=1"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk'));</script> But on the javascript sdk page: <div id="fb-root"></div> <script> window.fbAsyncInit = function() { FB.init({ appId : 'YOUR_APP_ID', // App ID channelUrl : '//WWW.YOUR_DOMAIN.COM/channel.html', // Channel File status : true, // check login status cookie : true, // enable cookies to allow the server to access the session xfbml : true // parse XFBML }); // Additional initialization code here }; // Load the SDK Asynchronously (function(d){ var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0]; if (d.getElementById(id)) {return;} js = d.createElement('script'); js.id = id; js.async = true; js.src = "//connect.facebook.net/en_US/all.js"; ref.parentNode.insertBefore(js, ref); }(document)); </script>

  • php: autoload exception handling.

    - by YuriKolovsky
    Hello again, I'm extending my previous question (Handling exceptions within exception handle) to address my bad coding practice. I'm trying to delegate autoload errors to a exception handler. <?php function __autoload($class_name) { $file = $class_name.'.php'; try { if (file_exists($file)) { include $file; }else{ throw new loadException("File $file is missing"); } if(!class_exists($class_name,false)){ throw new loadException("Class $class_name missing in $file"); } }catch(loadException $e){ header("HTTP/1.0 500 Internal Server Error"); $e->loadErrorPage('500'); exit; } return true; } class loadException extends Exception { public function __toString() { return get_class($this) .

"{$this->getTraceAsString()}"; } public function loadErrorPage($code){ try { $page = new pageClass(); echo $page->showPage($code); }catch(Exception $e){ echo 'fatal error: ', $code; } } } $test = new testClass(); ?> the above script is supposed to load a 404 page if the testClass.php file is missing, and it works fine, UNLESS the pageClass.php file is missing as well, in which case I see a "Fatal error: Class 'pageClass' not found in D:\xampp\htdocs\Test\PHP\errorhandle\index.php on line 29" instead of the "fatal error: 500" message I do not want to add a try/catch block to each and every class autoload (object creation), so i tried this. What is the proper way of handling this?

  • How can I generate an "unlimited" world?

    - by snowlord
    I would like to create a game with an endless (in reality an extremely large) world in which the player can move about. Whether or not I will ever get around to implement the game is one matter, but I find the idea interesting and would like some input on how to do it. The point is to have a world where all data is generated randomly on-demand, but in a deterministic way. Currently I focus on a large 2D map from which it should be possible to display any part without knowledge about the surrounding parts. I have implemented a prototype by writing a function that gives a random-looking, but deterministic, integer given the x and y of a pixel on the map (see my recent question about this function). Using this function I populate the map with "random" values, and then I smooth the map using a simple filter based on the surrounding pixels. This makes the map dependent on a few pixels outside its edge, but that's not a big problem. The final result is something that at least looks like a map (especially with a good altitude color map). Given this, one could maybe first generate a coarser map which is used to generate bigger differences in altitude to create mountain ranges and seas. Anyway, that was my idea, but I am sure that there exist ways to do this already and I also believe that given the specification, many of you can come up with better ideas. EDIT: Forgot the link to my question.

  • Refresh table after using jQuery .append()

    - by Aaron Salazar
    The following code gets a JSON object and then spits its contents out into a <table>. The first time I do it I get my JSON content just fine. However, when I refresh, the refreshed data is stuck onto the bottom of my table. How do I refresh the data to show the new data only? I tried using .remove() but there was an obvious deleting and then a refresh of data. $(function() { $('#ReportedIssue').change(function() { //$('.data').remove() $.getJSON('/CurReport/GetUpdatedTableResults', function(json) { for (var i = 0; i < json.GetDocumentResults.length; i++) { $('#DocumentInfoTable').append( "<tr class='data'>" + "<td>" + json.GetDocumentResults[i].Document.DocumentId + "</td>" + "<td>" + json.GetDocumentResults[i].Document.LanguageCode + "</td>" + "<td>" + json.GetDocumentResults[i].ReportedIssue + "</td>" + "<td>" + json.GetDocumentResults[i].PageNumber + "</td>" + "</tr>" ); }; }); }); }); Thank you, Aaron

This is what I have so far, and I make use of the List.hd built-in function, but not surprisingly, I'm getting the failure "hd" error: let rec combineSameHead list nlist = match list with | [] -> []@nlist | h::t -> if List.hd h = List.hd (List.hd t) then combineSameHead t nlist@uniq(h@(List.hd t)) else combineSameHead t nlist@h;; So for example, if I have this list: [[Sentence; Quiet]; [Sentence; Grunt]; [Sentence; Shout]] I want to combine it into: [[Sentence; Quiet; Grunt; Shout]] The function uniq I wrote just removes all duplicates within a list. Please let me know how I would go about completing this. Thanks in advance!

    Hi this is my code: Is is possible to get more photos from flickr. What is the standard / default number? $(document).ready(function(){ $.getJSON("http://api.flickr.com/services/feeds/photos_public.gne?id=48719970@N07&lang=en-us&format=json&jsoncallback=?", function(data){ $.each(data.items, function(i, item){ var newurl = 'url(' + item.media.m + ')'; $("<div class='images'/>").css('background', newurl).css('backgroundPosition','top center').css('backgroundRepeat','no-repeat').appendTo("#images").wrap("<a target=\"_blank\ href='" + item.link + "'></a>"); }) $("#title").html(data.title); $("#description").html(data.description); $("#link").html("<a href='" + data.link + "' target=\"_blank\">Visit the Viget Inspiration Pool!</a>"); //Notice that the object here is "data" because that information sits outside of "items" in the JSON feed $('.jcycleimagecarousel').cycle({ fx: 'fade', speed: 300, timeout: 3000, next: '#next', prev: '#prev', pause: 1, random: 1 }); }); });

  • jQuery noobie can't make a checked checkbox show an alert.

    - by Kyle Sevenoaks
    I found this answer before, to fire an alert if the button is pressed but the checkbox isn't checked. Why won't this work? <input value="1" type="checkbox" name="salgsvilkar" ID="checkbox2" style="float:left;" onclick="document.getElementById('scrollwrap').style.cssText='border-color:#85c222; background-color:#E5F7C7;';" /><label for="checkbox2" class="akslabel">Salgs og leveringsvilkår er lest og akseptert</label> </span> {literal} <script type="text/javascript"> $(function() { //checkbox $("#checkbox2").click(function(){ //if this... //alert("this")... if($("#checkbox2").is(':checked')) { alert("im checked"); } }); //button $("#fullfor_btn").click(function(e){ if(!$("#checkbox2").is(':checked')) { alert("you did not check the agree to terms..."); e.preventDefault(); } }); } </script> {/literal} This on another .tpl: <label></label> <button type="submit" class="submit" name="{$method}" id="fullfor_btn" title="Fullfør bestillingen nå" value="">&nbsp;</button> What could be going wrong? The jQuery doesn't fire anything at all.
