  • Which key value store is the most promising/stable?

    - by Mike Trpcic
    I'm looking to start using a key/value store for some side projects (mostly as a learning experience), but so many have popped up in the recent past that I've got no idea where to begin. Just listing from memory, I can think of: CouchDB MongoDB Riak Redis Tokyo Cabinet Berkeley DB Cassandra MemcacheDB And I'm sure that there are more out there that have slipped through my search efforts. With all the information out there, it's hard to find solid comparisons between all of the competitors. My criteria and questions are: (Most Important) Which do you recommend, and why? Which one is the fastest? Which one is the most stable? Which one is the easiest to set up and install? Which ones have bindings for Python and/or Ruby? Edit: So far it looks like Redis is the best solution, but that's only because I've gotten one solid response (from ardsrk). I'm looking for more answers like his, because they point me in the direction of useful, quantitative information. Which Key-Value store do you use, and why? Edit 2: If anyone has experience with CouchDB, Riak, or MongoDB, I'd love to hear your experiences with them (and even more so if you can offer a comparative analysis of several of them)

  • Validate domain against LDAP?

    - by lucian.jp
    I have a procedure to get the name of the logged user show on the site. I get it this way : var winIdentity = (WindowsIdentity) HttpContext.Current.User.Identity; if (winIdentity != null) { string domainUser = winIdentity.Name.Replace(@"\", "/"); string domain = winIdentity.Name.Split('\\')[0]; string user = winIdentity.Name.Split('\\')[1]; var myDe = new DirectoryEntry(ConfigurationManager.ConnectionStrings["LDAP"].ConnectionString, ConfigurationManager.AppSettings["LDAPCredentials"].Split(';')[0], ConfigurationManager.AppSettings["LDAPCredentials"].Split(';')[1]); var deSearcher = new DirectorySearcher(myDe) {Filter = "(&(sAMAccountName=" + user + "))"}; SearchResult result = deSearcher.FindOne(); if (result != null) { DirectoryEntry userDe = result.GetDirectoryEntry(); lblNameAD.Text = string.Format(lblNameAD.Text, userDe.Properties["givenName"].Value, userDe.Properties["sn"].Value); } else { var adEntry = new DirectoryEntry("WinNT://" + domainUser); string fullname = adEntry.Properties["FullName"].Value.ToString(); lblNameAD.Text = string.Format(lblNameAD.Text, !string.IsNullOrEmpty(fullname) ? fullname : user, null); } } Probleme id that if I have a local useraccount with the same username that one from LDAP, it passes the check and return the name. EX: local\MyUser domain\MyUser Both return the name from AD even if the one from local isn't a domain account. It would be perfect if I could search in LDAP for domainuser, but it seems I can't. I also tried to restrict the DC with the DirectorySearcher but the domain name is "domain", but I only have "dc=dom" and "dc=com" and no DC for full domain name.

  • Format for storing contacts in a database

    - by Gart
    I'm thinking of the best way to store personal contacts in a database for a business application. The traditional and straightforward approach would be to create a table with columns for each element, i.e. Name, Telephone Number, Job title, Address, etc... However, there are known industry standards for this kind of data, like for example vCard, or hCard, or vCard-RDF/XML or even Windows Contacts XML Schema. Utilizing an standard format would offer some benefits, like inter-operablilty with other systems. But how can I decide which method to use? The requirements are mainly to store the data. Search and ordering queries are highly unlikely but possible. The volume of the data is 100,000 records at maximum. My database engine supports native XML columns. I have been thinking to use some XML-based format to store the personal contacts. Then it will be possible to utilize XML indexes on this data, if searching and ordering is needed. Is this a good approach? Which contacts format and schema would you recommend for this?

  • KD-Trees and missing values (vector comparison)

    - by labratmatt
    I have a system that stores vectors and allows a user to find the n most similar vectors to the user's query vector. That is, a user submits a vector (I call it a query vector) and my system spits out "here are the n most similar vectors." I generate the similar vectors using a KD-Tree and everything works well, but I want to do more. I want to present a list of the n most similar vectors even if the user doesn't submit a complete vector (a vector with missing values). That is, if a user submits a vector with three dimensions, I still want to find the n nearest vectors (stored vectors are of 11 dimensions) I have stored. I have a couple of obvious solutions, but I'm not sure either one seem very good: Create multiple KD-Trees each built using the most popular subset of dimensions a user will search for. That is, if a user submits a query vector of thee dimensions, x, y, z, I match that query to my already built KD-Tree which only contains vectors of three dimensions, x, y, z. Ignore KD-Trees when a user submits a query vector with missing values and compare the query vector to the vectors (stored in a table in a DB) one by one using something like a dot product. This has to be a common problem, any suggestions? Thanks for the help.

  • Setting nested object to null when selected option has empty value

    - by Javi
    Hello, I have a Class which models a User and another which models his country. Something like this: public class User{ private Country country; //other attributes and getter/setters } public class Country{ private Integer id; private String name; //other attributes and getter/setters } I have a Spring form where I have a combobox so the user can select his country or can select the undefined option to indicate he doen't want to provide this information. So I have something like this: <form:select path="country"> <form:option value="">-Select one-</form:option> <form:options items="${countries}" itemLabel="name" itemValue="id"/> </form:select> In my controller I get the autopopulated object with the user information and I want to have country set to null when the "-Select one-" option has been selected. So I have set a initBinder with a custom editor like this: @InitBinder protected void initBinder(WebDataBinder binder) throws ServletException { binder.registerCustomEditor(Country.class, "country", new CustomCountryEditor()); } and my editor do something like this: public class CustomCountryEditor(){ @Override public String getAsText() { //I return the Id of the country } @Override public void setAsText(String str) { //I search in the database for a country with id = new Integer(str) //and set country to that value //or I set country to null in case str == null } } When I submit the form it works because when I have country set to null when I have selected "-Select one-" option or the instance of the country selected. The problem is that when I load the form I have a method like the following one to load the user information. @ModelAttribute("user") public User getUser(){ //loads user from database } The object I get from getUser() has country set to a specific country (not a null value), but in the combobox is not selected any option. I've debugged the application and the CustomCountryEditor works good when setting and getting the text, thoughgetAsText method is called for every item in the list "countries" not only for the "country" field. Any idea? Is there a better way to set null the country object when I select no country option in the combobox? Thanks

  • Lift XML Parsing Error

    - by bstevens90
    I know there are other questions on this and I have read through almost all of them and none of them solved my problem. I have inside a home directory: def search(in: NodeSeq) : NodeSeq = { bind("work", in, "docId" -> text("", did = _), "visitId" -> text("", vid = _), "provider" -> text("", prov = _), "emCode" -> text(ecode, ecode = _)) } along with: <lift:home.searchForm form="POST" multipart="true" > <table> <tr> <td>DocId</td> <td>VisitId</td> <td>Provider</td> <td>EanMCode</td> </tr> <tr> <td><work:docId /></td> <td><work:visitId /></td> <td><work:provider /></td> <td><work:emCode /></td> <td><button>Click Me!</button></td> </tr> </table> </lift:home.searchForm> Inside an html page. I have included xmlns:lift="http://liftweb.net/" in default.... I can't find anyway to fix this... I am getting XML Parsing Error: prefix not bound to a namespace Location: http://localhost:8080/ Line Number 29, Column 10: <td><work:docId></work:docId></td> in firefox. I have written similar code and had it working in another app and just cant even find anything im doing different thats not trivial naming... Thanks in advance!

  • Calling jquery function from ascx not working

    - by Metju
    Hi Guys, I'm having a problem with the following situation. I have an ascx which contains a submit button for a search criteria and I am trying to call a validation function in a js file I've used throughout the site (this is the first time I'm using it in an ascx). Now I've just tried this: <script type="text/javascript" src="js/jquery-1.3.2.js"></script> <script type="text/javascript" src="js/jsAdmin_Generic_SystemValidation.js"></script> <script type="text/javascript"> $(document).ready(function () { $(".submitBtn").click(function (e) { alert("test"); alert($.Validate()); alert("test 2"); }); }); </script> The file is being referenced correctly as I am already seeing posts in Firebug that are done by it. This is the function: jQuery.extend({ Validate: function () { does validation... }); Now at first I was getting "Validate() is not a function" in firebug. Since I did that alert testing, I am getting the first alert, then nothing with no errors. Can anyone shed some light? Thanks

  • jQuery XML loading and then innerfade effect

    - by Ryan Max
    Hello, I think I can explain myself without code, so for brevity's sake here we go: I am using jquery to pull data from an xml and put it into a ul on the page with each xml entry as a li. This is working great! However, what I am trying to do afterwards is use the innerfade plugin to make a simple animation between each of the li's. It's not working though, as it is still just loading the static list with each item visible (whereas if innerfade was working it would only display the first....then fade into the second, etc) It's not an innerfade problem however, because if I add the list in manually to the page (not injecting it with jquery) then the innerfade works fine. I'm relatively new to DOM scripting, so I think I am missing something here. I'm not quite sure how jQuery sequences everything, and I'm having trouble phrasing my question in a search engine friendly manner so here I am. Is it possible to have jquery pull the data from xml, then inject it into the page, then have innerfade work it's magic? Or am I thinking about this the wrong way? xml code: $.ajax({ type: "GET", url: "xml/playlist.xml", dataType: "xml", success: function(xml) { $(xml).find('song').each(function(){ var name = $(this).attr('title'); var date = $(this).attr('artist'); var message = $(this).attr('path'); $('<li></li>').html('<span id="an_name">'+name+'</span><span id="an_date">'+date+'</span><span id="an_message">'+message+'</span>').appendTo('#anniversary'); }); } }); innerfade code: <script type="text/javascript"> jQuery.noConflict(); jQuery(document).ready( function(){ jQuery('#anniversary').innerfade({ speed: 1000, timeout: 5000, type: 'sequence', }); });

  • Python - Open default mail client using mailto, with multiple recipients

    - by victorhooi
    Hi, I'm attempting to write a Python function to send an email to a list of users, using the default installed mail client. I want to open the email client, and give the user the opportunity to edit the list of users or the email body. I did some searching, and according to here: http://www.sightspecific.com/~mosh/WWW_FAQ/multrec.html It's apparently against the RFC spec to put multiple comma-delimited recipients in a mailto link. However, that's the way everybody else seems to be doing it. What exactly is the modern stance on this? Anyhow, I found the following two sites: http://2ality.blogspot.com/2009/02/generate-emails-with-mailto-urls-and.html http://www.megasolutions.net/python/invoke-users-standard-mail-client-64348.aspx which seem to suggest solutions using urllib.parse (url.parse.quote for me), and webbrowser.open. I tried the sample code from the first link (2ality.blogspot.com), and that worked fine, and opened my default mail client. However, when I try to use the code in my own module, it seems to open up my default browser, for some weird reason. No funny text in the address bar, it just opens up the browser. The email_incorrect_phone_numbers() function is in the Employees class, which contains a dictionary (employee_dict) of Employee objects, which themselves have a number of employee attributes (sn, givenName, mail etc.). Full code is actually here (http://stackoverflow.com/questions/2963975/python-converting-csv-to-objects-code-design) from urllib.parse import quote import webbrowser .... def email_incorrect_phone_numbers(self): email_list = [] for employee in self.employee_dict.values(): if not PhoneNumberFormats.standard_format.search(employee.telephoneNumber): print(employee.telephoneNumber, employee.sn, employee.givenName, employee.mail) email_list.append(employee.mail) recipients = ', '.join(email_list) webbrowser.open("mailto:%s?subject=%s&body=%s" % (recipients, quote("testing"), quote('testing')) ) Any suggestions? Cheers, Victor

  • Testing performance of queries in mysl

    - by Unreason
    I am trying to setup a script that would test performance of queries on a development mysql server. Here are more details: I have root access I am the only user accessing the server Mostly interested in InnoDB performance The queries I am optimizing are mostly search queries (SELECT ... LIKE '%xy%') What I want to do is to create reliable testing environment for measuring the speed of a single query, free from dependencies on other variables. Till now I have been using SQL_NO_CACHE, but sometimes the results of such tests also show caching behaviour - taking much longer to execute on the first run and taking less time on subsequent runs. If someone can explain this behaviour in full detail I might stick to using SQL_NO_CACHE; I do believe that it might be due to file system cache and/or caching of indexes used to execute the query, as this post explains. It is not clear to me when Buffer Pool and Key Buffer get invalidated or how they might interfere with testing. So, short of restarting mysql server, how would you recommend to setup an environment that would be reliable in determining if one query performs better then the other?

  • Passing a list of ints to WebMethod using jQuery and ajax.

    - by birdus
    I'm working on a web page (ASP.NET 4.0) and am just starting simple to try and get this ajax call working (I'm an ajax/jQuery neophyte) and I'm getting an error on the call. Here's the js: var TestParams = new Object; TestParams.Items = new Object; TestParams.Items[0] = 1; TestParams.Items[1] = 5; TestParams.Items[2] = 10; var finalObj = JSON.stringify(TestParams); var _url = 'AdvancedSearch.aspx/TestMethod'; $(document).ready(function () { $.ajax({ type: "POST", url: _url, data: finalObj, contentType: "application/json; charset=utf-8", dataType: "json", success: function (msg) { $(".main").html(msg.d); }, error: function (xhr, ajaxOptions, thrownError) { alert(thrownError.toString()); } }); Here's the method in my code behind file: [Serializable] public class TestParams { public List<int> Items { get; set; } } public partial class Search : Page { [WebMethod] public static string TestMethod(TestParams testParams) { // I never hit a breakpoint in here // do some stuff // return some stuff return ""; } } Here's the stringified json I'm sending back: {"Items":{"0":1,"1":5,"2":10}} When I run it, I get this error: Microsoft JScript runtime error: 'undefined' is null or not an object It breaks on the error function. I've also tried this variation on building the json (based on a sample on a website) with this final json: var TestParams = new Object; TestParams.Positions = new Object; TestParams.Positions[0] = 1; TestParams.Positions[1] = 5; TestParams.Positions[2] = 10; var DTO = new Object; DTO.positions = TestParams; var finalObj = JSON.stringify(DTO) {"positions":{"Positions":{"0":1,"1":5,"2":10}}} Same error message. It doesn't seem like it should be hard to send a list of ints from a web page to my webmethod. Any ideas? Thanks, Jay

  • Why can I query with an int but not a string here? PHP MySQL Datatypes

    - by CT
    I am working on an Asset Database problem. I receive $id from $_GET["id"]; I then query the database and display the results. This works if my id is an integer like "93650" but if it has other characters like "wci1001", it displays this MySQL error: Unknown column 'text' in 'where clause' All fields in tables are of type: VARCHAR(50) What would I need to do to be able to use this query to search by id that includes other characters?

  • TinyMce imagemanager won't generate image path when used with an iframe

    - by Tom
    I have successfully setup tinymce to work on a page within an iframe. Everything works perfectly. However, when you use imagemanager to pick an image to be inserted or replaced in the editor it will not copy the path(and filename) of the image to the "Image URL" input in the "Insert/edit image" box. The box will either remain empty or keep the address of the previous image. The behaviour is the same with the filemanager plugin. tinyMCE.init( { mode : "none", editor_selector : "mceEditor", theme : "advanced", plugins : "filemanager,imagemanager,autoresize,safari,pagebreak,style,layer,table,save,advhr,advimage,advlink,emotions,iespell,insertdatetime,preview,media,searchreplace,print,contextmenu,paste,directionality,fullscreen,noneditable,visualchars,nonbreaking,xhtmlxtras,template,inlinepopups,spellchecker", theme_advanced_buttons1 : "insertfile,insertimage,advimage,imagemanager,bold,italic,underline,|,justifyleft,justifycenter,justifyright,justifyfull,nonbreaking,cut,copy,paste,pastetext,pasteword,|,search,replace,|,bullist,numlist", theme_advanced_buttons2 : "blockquote,|,link,unlink,anchor,image,cleanup,help,code,|,insertdate,inserttime,|,forecolor,backcolor,|,charmap,iespell,media,advhr", theme_advanced_layout_manager : "SimpleLayout", theme_advanced_buttons3 : "tablecontrols,|,hr,removeformat,visualaid,|,sub,sup,strikethrough", theme_advanced_buttons4 : "styleselect,formatselect,fontselect,fontsizeselect,|,undo,redo,|,spellchecker", theme_advanced_toolbar_location : "external", theme_advanced_toolbar_align : "left", theme_advanced_statusbar_location : "bottom", relative_urls : true, document_base_url : "http://devtom.ecitb.org.uk/", auto_resize : true, content_css : "/custom/css/style.css", extended_valid_elements : "iframe[height|width|src|frameborder|scrolling]", }); /* The following code comes from- http://tinymce.moxiecode.com/punbb/viewtopic.php?id=12966 Without it the editor only loads 10% of the time.

  • How to select the first property with unknown name and first item from array in JSON

    I actually have two questions, both are probably simple, but for some odd reason I cant figure it out... I've worked with JSON 100s of times before too! but here is the JSON in question: {"69256":{ "streaminfo":{ "stream_ID":"1025", "sourceowner_ID":"2", "sourceowner_avatar":"http:\/\/content.nozzlmedia.com\/images\/sourceowner_avatar2.jpg", "sourceownertype_ID":"1", "stream_name":"Twitter", "streamtype":"Social media" "appsarray":[] }, "item":{ "headline":"Charboy", "main_image":"http:\/\/content.nozzlmedia.com\/images\/author_avatar173212.jpg", "summary":"ate a tomato and avocado for dinner...", "nozzl_captured":"2010-05-12 23:02:12", "geoarray":[{ "state":"OR", "county":"Multnomah", "city":"Portland", "neighborhood":"Downtown", "zip":"97205", "street":"462 SW 11th Ave", "latitude":"45.5219", "longitude":"-122.682" }], "full_content":"ate a tomato and avocado for dinner tonight. such tasty foods. just enjoyable.", "body_text":"ate a tomato and avocado for dinner tonight. such tasty foods. just enjoyable.", "author_name":"Charboy", "author_avatar":"http:\/\/content.nozzlmedia.com\/images\/author_avatar173212.jpg", "fulltext_url":"http:\/\/twitter.com\/charboy\/statuses\/13889868936", "leftovers":{ "twitter_id":"tag:search.twitter.com,2005:13889868936", "date":"2010-05-13T02:59:59Z", "location":"iPhone: 45.521866,-122.682262" }, "wordarray":{ "0":"ate", "1":"tomato", "2":"avocado", "3":"dinner", "4":"tonight", "5":"tasty", "6":"foods", "7":"just", "8":"enjoyable", "9":"Charboy", "11":"Twitter", "13":"state:OR", "14":"county:Multnomah, OR", "15":"city:Portland, OR", "16":"neighborhood:Downtown", "17":"zip:97205" } } } } Question 1: How do I loop through each item (69256) when the number is random? e.g. item 1 is 123, item2 is 646? Like, for example, a normal JSON feed would have something like: {'item':{'blah':'lorem'},'item':{'blah':'ipsum'}} the JS would be like console.log(item.blah) to return lorem then ipsum in a loop How do I do it when i dont know the first item of the object? Question 2: How do I select items from the geoarray object? I tried: json.test.item.geoarray.latitude and json.test.item.geoarray['latitude']

  • Use jQuery to find and add an image tooltip

    - by lund.mikkel
    Hey people Okay, what I'm trying to accomplish is a simple tool tip that, when you hover over the name of a color, shows a little image of that color. The html markup looks like this: <label class="colorPicker"> <input type="radio" checked="" id="20" value="20" name="id[2]"> <img width="16" height="16" title=" DinoBlack Mat " alt="DinoBlack Mat" src="images/attributes/color/dinoblack_mat.jpg">DinoBlack Mat </label> <label class="colorPicker"> <input type="radio" id="874" value="874" name="id[2]"> <img width="16" height="16" title="XrayBlue shiny" alt="XrayBlue shiny" src="images/attributes/color/xrayblue_shiny.jpg">XrayBlue shiny </label> I'm using the jQuery plugin "Tooltip" and I've added following to my main js-file: $('.colorPicker').tooltip({ track: true, delay: 0, showURL: false, fade: 250, bodyHandler: function() { return $("<img/>").attr("src", [THE SOURCE FOR THE IMAGE]); } }); The idea is simply that the image should be hidden by default. But when you hover over the text the little thumbnail shows up and makes it easy to recognize the color. The problem is I haven't got a clue how to get the src for the thumbnail. I don't know how to extract the src from the img inside the selected element. I've tried various combinations using the this keyword, but nothing seemed to work. I've also tried to add the src path as a rel attribute to the label, but also without any success. Should be needless to say I also control the PHP-output... I really hope you can help me. I've search the web for days without any luck. I'm getting desperate :D /Mikkel Lund

  • The best way to build iPhone/iPad static libraries?

    - by Derek Clarkson
    Hi everyone, I have a couple of static Phone/iPad libraries I an working on. The problem I am looking for advise on is the best way to package the libraries. My objective is to make it easy to use the libraries in other projects and include the correct one in a build with minimal problems. To make it more interesting I currently build 4 versions of each library as follows armv6/armv7 release (devices) i386 release (simulator) armv6/armv7 debug (devices) i386 debug (simulator) The difference between the release and debug versions is that the debug versions contain a lot of NSLog(...) code which enables people to see whats going on internally as an aid to debugging. Currently when I build the whole projects I arrange the libraries into two directories like this: release lib-device.a lib-simulator.a debug lib-device.a lib-simulator.a This works ok except that when include in projects, both paths are added to the library search path and switching a target from one to the other is a pain. Or alternatively I end up with two targets. The alternative I am thinking of is to change the directories like this: release device lib.a simulator lib.a debug device lib.a simulator lib.a In playing with XCode is appears that all xcode uses the lbrary references of a project for is to get the name of the library file, which it then looks up in the library paths. Thus by parameterising the library path with the current built type and target device, I can effectively auto switch. What do you guys think? Is there a better way to do this? ciao Derek

  • Best way to do interprocess communication on Mac OS X

    - by jbrennan
    I'm looking at building a Cocoa application on the Mac with a back-end daemon process (really just a mostly-headless Cocoa app, probably), along with 0 or more "client" applications running locally (although if possible I'd like to support remote clients as well; the remote clients would only ever be other Macs or iPhone OS devices). The data being communicated will be fairly trivial, mostly just text and commands (which I guess can be represented as text anyway), and maybe the occasional small file (an image possibly). I've looked at a few methods for doing this but I'm not sure which is "best" for the task at hand. Things I've considered: Reading and writing to a file (…yes), very basic but not very scalable. Pure sockets (I have no experience with sockets but I seem to think I can use them to send data locally and over a network. Though it seems cumbersome if doing everything in Cocoa Distributed Objects: seems rather inelegant for a task like this NSConnection: I can't really figure out what this class even does, but I've read of it in some IPC search results I'm sure there are things I'm missing, but I was surprised to find a lack of resources on this topic.

  • jQuery: How to parse a multidemensional array?

    - by Allen G
    I'm not sure if the array is too deep or what, but I can't seem to get anything other than the keys and undefines. Help please! I'm using Codeigniter for development. Here is the PHP then the jQuery: $term = $this->input->post('search_term'); $this->db->like('book_title', $term); $search_query = $this->db->get('books'); $return = array(); $i = 0; if ($search_query->num_rows() > 1) { foreach($search_query->result() as $s) { $return['books']['book_id'] = $s->book_id; $return['books']['book_title'] = $s->book_title; $return['books']['book_price'] = $s->book_price; $i++; } } elseif ($search_query->num_rows() == 1) { echo 1; $i = 0; $return['book_id'] = $search_query->row('book_id'); $return['book_title'] = $search_query->row('book_title'); $return['book_price'] = $search_query->row('book_price'); } elseif ($search_query->num_rows() == 0) { echo 0; } echo json_encode($return); $("#search").change(function() { var searchTerm = $(this).val(); $.post("/contentcreator/search_by_term", { search_term: searchTerm }, function(data) { $("#book_scroller").empty(); var lengthHolder = data.books; for (var i = 0; i data.books.length; i++) { var row = '<li id="book_item_' + l + '">' + data.books['book_title'] +'</li>'; $("#book_scroller").append(row); }; i++; }, "json"); }); Thanks!

  • Personal Cache vs Memcache?

    - by Kerry
    I have a personal caching class, which can be seen here ( based off WordPress' ): http://pastie.org/988427 I recently learned about memcache and it said to memcache EVERYTHING: http://highscalability.com/blog/2010/5/17/7-lessons-learned-while-building-reddit-to-270-million-page.html My first thought was just to keep my class with the current functions and make it use memcache instead -- is there any downside to doing this? The main difference I see is that memcache stays on with the server from page to page, while mine is for 1 page load. The problem I see arising, and this is with any system, is that they're dynamic. They change all the time. Whether its search results, visible products, etc. etc. If it's all cached, won't the create a problem? Is there a way to handle this? Obviously if something is bringing back the same results everytime it would be cached, but that's why I was doing it on a per page load basis. I'm sure there is a way to handle this, or is the cache time usually set between 5 minutes and an hour?

  • Export database data to csv from view by date range asp.net mvc3

    - by Benjamin Randal
    I am trying to find a way to export data from my database and save it as a .csv file. Ideally the user will be able to select a date range on a view, which will display the data to be exported, then the user can click an "export to CSV" link. I've done quite a bit of searching and but have not found much specific enough to help me step through the process. Any help would be great. I would like to export data from this database model... { public class InspectionInfo { [Key] public int InspectionId { get; set; } [DisplayName("Date Submitted")] [DataType(DataType.Date)] // [Required] public DateTime Submitted { get; set; } [DataType(DataType.MultilineText)] [MaxLength(1000)] // [Required] public string Comments { get; set; } // [Required] public Contact Contact { get; set; } [ForeignKey("Contact")] public Int32 ContactId { get; set; } [MaxLength(100)] public String OtherContact { get; set; } I have a service for search also, just having difficulty implementing public SearchResults SearchInspections(SearchRequest request) { using (var db = new InspectionEntities()) { var results = db.InspectionInfos .Where( i=> ( (null == request.StartDate || i.Submitted >= request.StartDate.Value) && (null == request.EndDate || i.Submitted <= request.EndDate.Value) ) ) .OrderBy(i=>i.Submitted) .Skip(request.PageSize*request.PageIndex).Take(request.PageSize); return new SearchResults{ TotalResults=results.Count(), PageIndex=request.PageIndex, Inspections=results.ToList(), SearchRequest=request }; } }

  • SQL Selects on subsets

    - by Adam
    I need to check if a row exists in a database; however, I am trying to find the way to do this that offers the best performance. This is best summarised with an example. Let's assume I have the following table: dbo.Person( FirstName varchar(50), LastName varchar(50), Company varchar(50) ) Assume this table has millions of rows, however ONLY the column Company has an index. I want to find out if a particular combination of FirstName, LastName and Company exists. I know I can do this: IF EXISTS(select 1 from dbo.Person where FirstName = @FirstName and LastName = @LastName and Company = @Company) Begin .... End However, unless I'm mistaken, that will do a full table scan. What I'd really like it to do is a query where it utilises the index. With the table above, I know that the following query will have great performance, since it uses the index: Select * from dbo.Person where Company = @Company Is there anyway to make the search only on that subset of data? e.g. something like this: select * from ( Select * from dbo.Person where Company = @Company ) where FirstName = @FirstName and LastName = @LastName That way, it would only be doing a table scan on a much narrower collection of data. I know the query above won't work, but is there a query that would? Oh, and I am unable to create temporary tables, as the user will only have read access.

  • Querying a database using Cocoa.

    - by S1syphus
    Hello everybody. Before I start a disclaimer, I should add a little disclaimer, that I am relatively new to Cocoa development and C in general. However I do have a copy of 'Cocoa Programming for Mac OS X 3rd edition' by Aaron Hillegass, which I am working through and using as a base, if anybody has a copy I am using the 'AmaZone' example on page 346 as a template and base. I trying to develop a small client app that takes a search string then displays results from a database accordingly. The database will contain a: list of files, their location, description & creation date, so for the moment the field number and types will remain the same. After looking around on SO, I saw something like: NSURL *myURL = [NSURL URLWithString:@"http://www.myserver.com/results.php"]; NSArray *sqlResults = [[NSArray alloc] initWithContentsOfURL:myURL]; I've worked with php before, so my current thinking after seeing this is create a php script on the server that queries the database, and creates an XML output. And with the XML response, just parse it. Would this be ok? as is there any major pitfalls anybody can see, that I can't. I know there are some database bundles, I've had a look at BaseTen for Postgres, but being relatively new to this, didn't want to get in over my head. Or if anybody else has any other suggestions and ideas, they would be greatly appreciated.

  • How to save highlighting to a database

    - by vman
    Hi I am trying to highlight a part of the text on my website. This highlighted text will be saved for the specific user in a database and when the document is opened again it will show the previously highlighted text. I assumed I would be using javascript to highlight the text but I cannot seem to find a way to pinpoint where the word is that I am highlighting. function getSelText() { var txt = ''; if (window.getSelection) { txt = window.getSelection(); } else if (document.getSelection) { txt = document.getSelection(); } else if (document.selection) { txt = document.selection.createRange().text; } else return ""; return txt; } I am using that to get the selection but I cannot figure out where the selection is in the text. The biggest annoyance is when I have duplicates within the line or text so if I were to use search then I would find the first instance and not the one I was looking for. So the question is : How do you pinpoint a word or a selection in the entire document?

  • Web application date time localization best practice at 201x

    - by Hieu Lam
    Hi all, I have worked for various web projects but correct date time localization have not been done and considered throroughly so I want to ask this very typical problem here and I want to hear comments from expert in this problem What is the correct strategy for storing a date/time value from client from server As I understand, because of locale and timezone so we have to do the conversion, I have heard about GMT or UTC time and after do some search it seems that UTC is more accurate ? so we will convert from client time - UTC+0 when saving and when we read the value from server to client, we convert from server time back to client time again ? However, I see in some website, at the bottom have the sentence "All times are in UTC", "All times are in GMT" and also "All times are in your local time". So maybe not all the sites do the convertion back and forth ? And in that case the user has to manually do the date/time conversion ? How to display the date/time convenient to user based on his locale and region How to provide personalization on date/time value ? I had one time depends on vbscript to do the display and the format is read from windows regional and format settings automatically. But without vbscript how can we determine a date/time pattern for a user of a specific locale. Do we have to store a mapping between a locale and pattern somewhere and do the conversion at the server side ? Although date/time conversion is needed in most case, there's situation where only date matter for example if my birthday is 2 Feb 1980, it should be the same for all locale and no conversion should be done. How can we address this issue.
