  • SQL Server Index cost

    - by yellowstar
    I have read that one of the tradeoffs for adding table indexes in SQL Server is the increased cost of insert/update/delete queries to benefit the performance of select queries. I can conceptually understand what happens in the case of an insert because SQL Server has to write entries into each index matching the new rows, but update and delete are a little more murky to me because I can't quite wrap my head around what the database engine has to do. Let's take DELETE as an example and assume I have the following schema (pardon the pseudo-SQL) TABLE Foo col1 int ,col2 int ,col3 int ,col4 int PRIMARY KEY (col1,col2) INDEX IX_1 col3 INCLUDE col4 Now, if I issue the statement DELETE FROM Foo WHERE col1=12 AND col2 > 34 I understand what the engine must do to update the table (or clustered index if you prefer). The index is set up to make it easy to find the range of rows to be removed and do so. However, at this point it also needs to update IX_1 and the query that I gave it gives no obvious efficient way for the database engine to find the rows to update. Is it forced to do a full index scan at this point? Does the engine read the rows from the clustered index first and generate a smarter internal delete against the index? It might help me to wrap my head around this if I understood better what is going on under the hood, but I guess my real question is this. I have a database that is spending a significant amount of time in delete and I'm trying to figure out what I can do about it. When I display the execution plan for the deletion, it just shows an entry for "Clustered Index Delete" on table Foo which lists in the details section the other indices that need to be updated but I don't get any indication of the relative cost of these other indices. Are they all equal in this case? Is there some way that I can estimate the impact of removing one or more of these indices without having to actually try it?

  • Reverse ordered list for jquery submitted comments

    - by g-man
    Hey guys I have one more question lol. I am using a script that allows users to submit comments through jquery ajax, however when they are submitted, the submitted comments submit at the bottom of the other comments which are sorted in descending order (newest on top) when the page first loads (due to mysql query). Is there a way to make it submit on top through some sort of sorting javascript function? function prepare(response) { var d = new Date(); count++; d.setTime(response.time*1000); var mytime = d.getHours()+':'+d.getMinutes()+':'+d.getSeconds(); var string = '<li class="shoutbox-list" id="list-'+count+'">' + '<span class="date">'+mytime+'</span>' + '<span class="shoutbox-list-nick"><a href="statistics.php?user='+response.user+'">'+response.user+'</a>:</span>' + '<span class="msg">'+response.message+'</span>' +'</li>'; return string; } function success(response, status) { if(status == 'success') { lastTime = response.time; $('#daddy-shoutbox-list').append(prepare(response)); $('input[name=message]').attr('value', '').focus(); $('#list-'+count).fadeIn('slow'); timeoutID = setTimeout(refresh, 3000); } } <div id="daddy-shoutbox"> <ol id="daddy-shoutbox-list"></ol> </div>

  • Storing Arbitrary Contact Information in Ruby on Rails

    - by Anthony Chivetta
    Hi, I am currently working on a Ruby on Rails app which will function in some ways like a site-specific social networking site. As part of this, each user on the site will have a profile where they can fill in their contact information (phone numbers, addresses, email addresses, employer, etc.). A simple solution to modeling this would be to have a database column per piece of information I allow users to enter. However, this seems arbitrary and limited. Further, to support allowing users to enter as many phone numbers as they would like requires the addition of another database table and joins. It seems to me that a better solution would be to serialize all the contact information entered by a user into a single field in their row. Since I will never be conditioning a SQL query on this information, such a solution wouldn't be any less efficient. Ideally, I would like to use a vCard as my serialization format. vCards are the standard solution to storing contact information across the web, and reusing tested solutions is a Good Thing. Alternative serialization formats would include simply marshaling a ruby hash, or YAML. Regardless of serialization format, supporting the reading and updating of this information in a rails-like way seems to be a major implementation challenge. So, here's the question: Has anyone seen this approach used in a rails application? Are there any rails plugins or gems that make such a system easy to implement? Ideally what I would like is an acts_as_vcard to add to my model object that would handle editing the vcard for me and saving it back to the database.

  • Web Hosting URL Length Limit?

    - by Isaac Waller
    Hello, I am designing a web application which is a tie in to my iPhone application. It sends massively large URLs to the web server (15000 about.) I was using NearlyFreeSpeech.net, but they only support URLS up to 2000 characters. I was wondering if anybody knows of web hosting that will support really large URLs? Thanks, Isaac Edit: My program needs to open a picture in Safari. I could do this 2 ways: send it base64 encoded in the URL and just echo the query parameters. first POST it to the server in my application, then the server would send back a unique ID after storing the photo in a database, which I would append to a URL which I would open in Safari which retrieved the photo from the database and delete it from the database. You see, I am lazy, and I know Mobile Safari can support URI's up to 80 000 characters, so I think this is a OK way to do it. If there is something really wrong with this, please tell me. Edit: I ended up doing it the proper POST way. Thanks.

  • How to setup Lucene search for a B2B web app?

    - by Bill Paetzke
    Given: 5000 databases (spread out over 5 servers) 1 database per client (so you can infer there are 1000 clients) 2 to 2000 users per client (let's say avg is 100 users per client) Clients (databases) come and go every day (let's assume most remain for at least one year) Let's stay agnostic of language or sql brand, since Lucene (and Solr) have a breadth of support The Question: How would you setup Lucene search so that each client can only search within its database? How would you setup the index(es)? Would you need to add a filter to all search queries? If a client cancelled, how would you delete their (part of the) index? (this may be trivial--not sure yet) Possible Solutions: Make an index for each client (database) Pro: Search is faster (than one-index-for-all method). Indices are relative to the size of the client's data. Con: I'm not sure what this entails, nor do I know if this is beyond Lucene's scope. Have a single, gigantic index with a database_name field. Always include database_name as a filter. Pro: Not sure. Maybe good for tech support or billing dept to search all databases for info. Con: Search is slower (than index-per-client method). Flawed security if query filter removed. For Example: Joel Spolsky said in Podcast #11 that his hosted web app product, FogBugz On-Demand, uses Lucene. He has thousands of on-demand clients. And each client gets their own database. His situation is quite similar to mine. Although, he didn't elaborate on the setup (particularly indices); hence, the need for this question. One last thing: I would also accept an answer that uses Solr (the extension of Lucene). Perhaps it's better suited for this problem. Not sure.

  • Loop XML including all its children using xpath and SimpleXMLElement

    - by Andersson
    Im having a big xml tree with a simple structure. All I want to do is get a node by its attribute using xpath and loop the children. param1 - correct language param1 & param3 - correct node by its id and the parents id. (Need to use parent id when multiplie id appears. The id is not declared as id in DTD) public function getSubmenuNodesRe($language, $id1,$id2) { $result = $this->xml->xpath("//*[@language='$language']//*[@id='$id1']//menuitem[@id='$id2']/*"); return $result; } This works well, I get the node Im expecting. I having no problems looping the array returned by the xpath query. But when i try to loop childnodes all attributes are gone and many of the methods also. Except getName(). function printNodeName($node) { echo $node->getName(). " - \"" . $node['id']. "\"<br>"; if($node->children()->getName() == "menuitem") { $s = $node->children(); printNodeName($s); } } $result = $xmlNode->getSubmenuNodesRe($_GET['language'], 'foo','bar'); if ($result) { while(list( , $node) = each($result)) { if ($node->getName() == "menuitem") { printNodeName($node); } } } Why is that? only the name will be printed for the $s. Really need help to solve this one, any assistance is deeply appreciated! Thanks for your time.

  • jQuery aspx error function always called, even with apparently valid return data

    - by M Katz
    I am making an ajax call using jQuery (jquery-1.5.2.min.js). The server receives the call. fiddler shows the response text coming back apparently correct. But back in javascript my error: function is called instead of my success: function, and the data of the parameters to the error function don't give much clue as to the problem. Here's the function where I make the initial call: function SelectCBGAtClickedPoint() { $.ajax( { type: "GET", dataType: "text", url: "http://localhost/ajax/SelectCBGAtPoint/1/2", success: function( msg ) { alert( "success: " + msg ); }, error: function( jqXHR, textStatus, errorThrown ) { alert( "error: " + jqXHR + textStatus + errorThrown ); } } ); } Here's the function where I handle the call in my cherrypy server code: def ajax( ajax, *args ): with lock: print "ajax request received: " + str( args ) cherrypy.response.headers[ "Content-Type" ] = "application/text" return "{ x: 0 }" Cherrypy is an odd beast, and I was thinking the problem must lie there. But as I say, I see both the query go out and the response come back in Fiddler. Here is what Fiddler shows as the raw view of the response: HTTP/1.1 200 OK Date: Mon, 11 Apr 2011 17:49:25 GMT Content-Length: 8 Content-Type: application/text Server: CherryPy/3.2.0 { x: 0 } Looks good, but then back in javascript, I get into the error: function, with the following values for the parameters (as shown in firebug): errorThrown = "" jqXHR = Object { readyState=0, status=0, statusText="error"} statusText = "error" I don't know where that word "error" is coming from. That string does not appear anywhere in my cherrypy server code. Note that even though I'm returning a JSON string I've set the send and receive types to "text" for now, just to simplify in order to isolate the problem. Any ideas why I'm getting this "error" reply, even when errorThrown is empty? Could it be that I haven't properly "initialized" either jQuery or jQuery.ajax?

  • Can I use the auto-generated Linq-to-SQL entity classes in 'disconnected' mode?

    - by Gary McGill
    Suppose I have an automatically-generated Employee class based on the Employees table in my database. Now suppose that I want to pass employee data to a ShowAges method that will print out name & age for a list of employees. I'll retrieve the data for a given set of employees via a linq query, which will return me a set of Employee instances. I can then pass the Employee instances to the ShowAges method, which can access the Name & Age fields to get the data it needs. However, because my Employees table has relationships with various other tables in my database, my Employee class also has a Department field, a Manager field, etc. that provide access to related records in those other tables. If the ShowAges method were to invoke any of those methods, this would cause lots more data to be fetched from the database, on-demand. I want to be sure that the ShowAges method only uses the data I have already fetched for it, but I really don't want to have to go to the trouble of defining a new class which replicates the Employee class but has fewer methods. (In my real-world scenario, the class would have to be considerably more complex than the Employee class described here; it would have several 'joined' classes that do need to be populated, and others that don't). Is there a way to 'switch off' or 'disconnect' the Employees instances so that an attempt to access any property or related object that's not already populated will raise an exception? If not, then I assume that since this must be a common requirement, there might be an already-established pattern for doing this sort of thing?

  • SQL to get list of dates as well as days before and after without duplicates

    - by Nathan Koop
    I need to display a list of dates, which I have in a table SELECT mydate AS MyDate, 1 AS DateType FROM myTable WHERE myTable.fkId = @MyFkId; Jan 1, 2010 - 1 Jan 2, 2010 - 1 Jan 10, 2010 - 1 No problem. However, I now need to display the date before and the date after as well with a different DateType. Dec 31, 2009 - 2 Jan 1, 2010 - 1 Jan 2, 2010 - 1 Jan 3, 2010 - 2 Jan 9, 2010 - 2 Jan 10, 2010 - 1 Jan 11, 2010 - 2 I thought I could use a union SELECT MyDate, DateType FROM ( SELECT mydate - 1 AS MyDate, 2 AS DateType FROM myTable WHERE myTable.fkId = @MyFkId; UNION SELECT mydate + 1 AS MyDate, 2 AS DateType FROM myTable WHERE myTable.fkId = @MyFkId; UNION SELECT mydate AS MyDate, 1 AS DateType FROM myTable WHERE myTable.fkId = @MyFkId; ) AS myCombinedDateTable This however includes duplicates of the original dates. Dec 31, 2009 - 2 Jan 1, 2009 - 2 Jan 1, 2010 - 1 Jan 2, 2010 - 2 Jan 2, 2010 - 1 Jan 3, 2010 - 2 Jan 9, 2010 - 2 Jan 10, 2010 - 1 Jan 11, 2010 - 2 How can I best remove these duplicates? I am considering a temporary table, but am unsure if that is the best way to do it. This also appears to me that it may provide performance issues as I am running the same query three separate times. What would be the best way to handle this request?

  • NHibernate: how to handle entity-based validation using session-per-request pattern, without control

    - by Seth Petry-Johnson
    What is the best way to do entity-based validation (each entity class has an IsValid() method that validates its internal members) in ASP.NET MVC, with a "session-per-request" model, where the controller has zero (or limited) knowledge of the ISession? Here's the pattern I'm using: Get an entity by ID, using an IFooRepository that wraps the current NH session. This returns a connected entity instance. Load the entity with potentially invalid data, coming from the form post. Validate the entity by callings its IsValid() method. If valid, call IFooRepository.Save(entity). Otherwise, display error message. The session is currently opened when the request begins and flushed when the request ends. Since my entity is connected to a session, flushing the session attempts to save the changes even if the object is invalid. What's the best way to keep validation logic in the entity class, limit controller knowledge of NH, and avoid saving invalid changes at the end of a request? Option 1: Explicitly evict on validation failure, implicitly flush: if the validation fails, I could manually evict the invalid object in the action method. If successful, I do nothing and the session is automatically flushed. Con: error prone and counter-intuitive ("I didn't call .Save(), why are my invalid changes being saved anyways?") Option 2: Explicitly flush, do nothing by default: By default I can dispose of the session on request end, only flushing if the controller indicates success. I'd probably create a SaveChanges() method in my base controller that sets a flag indicating success, and then query this flag when closing the session at request end. Pro: More intuitive to troubleshoot if dev forgets this step [relative to option 1] Con: I have to call IRepository.Save(entity)' and SaveChanges(). Option 3: Always work with disconnected objects: I could modify my repositories to return disconnected/transient objects, and modify the Repo.Save() method to re-attach them. Pro: Most intuitive, given that controllers don't know about NH. Con: Does this defeat many of the benefits I'd get from NH?

  • How to verify the SSL connection when calling a URI?

    - by robertokl
    Hello, I am developing a web application that is authenticated using CAS (A single-sign-on solution: http://www.ja-sig.org/wiki/display/CAS/Home). For security reasons, I need two things to work: The communication between CAS and my application needs to be secure My application needs to accept the certification coming from CAS, so that I can guarantee that the CAS responding is the real CAS server This is what I got so far: uri = URI.parse("https://www.google.com/accounts") https = Net::HTTP.new(uri.host, uri.port) https.use_ssl = (uri.scheme == 'https') https.verify_mode = (OpenSSL::SSL::VERIFY_PEER) raw_res = https.start do |conn| conn.get("#{uri.path}?#{uri.query}") end This works just great in Mac OS X. When I try to reach an insecure URI, it raises an exception, and when I try to reach a secure URI, it allows me normally, just like expected. The problem starts when I deploy my application on my Linux server. I tried in both Ubuntu and Red Hat. Independent of what URI I try to reach, it always raises this exception: OpenSSL::SSL::SSLError: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed from /usr/local/lib/ruby/1.8/net/http.rb:586:in `connect' from /usr/local/lib/ruby/1.8/net/http.rb:586:in `connect' from /usr/local/lib/ruby/1.8/net/http.rb:553:in `do_start' from /usr/local/lib/ruby/1.8/net/http.rb:542:in `start' from (irb):7 I think this have something to do with my installed OpenSSL package, but I can't be sure. This are my installed OpenSSL packages: openssl.x86_64 0.9.8e-12.el5 installed openssl-devel.x86_64 0.9.8e-12.el5 installed I tried using HTTParty as well, but it just ignores the SSL certificate. I hope someone can help me, or tell me about a gem that works the way I need. Thanks.

  • How should I manage my many-to-many relationships?

    - by wes
    Hello all, I have a database containing a couple tables: files and users. This relationship is many-to-many, so I also have a table called users_files_ref which holds foreign keys to both of the above tables. Here's the schema of each table: files - file_id, file_name users - user_id, user_name users_files_ref - user_file_ref_id, user_id, file_id I'm using Codeigniter to build a file host application, and I'm right in the middle of adding the functionality that enables users to upload files. This is where I'm running into my problem. Once I add a file to the files table, I will need that new file's id to update the users_files_ref table. Right now I'm adding the record to the files table, and then I imagined I'd run a query to grab the last file added, so that I can get the ID, and then use that ID to insert the new users_files_ref record. I know this will work on a small scale, but I imagine there is a better way of managing these records, especially in a heavy-traffic scenario. I am new to relational database stuff but have been around PHP for a while, so please bear with me here :-) I have primary and foreign keys set up correctly for the files, users, and users_files_ref tables, I'm just wondering how to manage the adding of file records for this scenario? Thanks for any help provided, it's much appreciated. -Wes

  • nhibernate - mapping with contraints

    - by Tobias Müller
    Hello everybody, I am having a Problem with my nhibernate-mapping and I can't find a solution by searching on stackoverflow/google/documentation. The database I am using has (amongst others) two tables. One is unit with the following fields: id enduring_id starts ends damage_enduring_id [...] The other one is damage, which has the following fields: id enduring_id starts ends [...] The units are assigned to a damage and one damage can have zero, one or more units working on it. Every time a unit moves to annother damage, the dataset is copied. The field "ends" of the old record and "starts" of the new record are set to the current time stamp, enduring_id stays the same. So if I want to know which units were working on a damage at a certain time, I do the following select: select * from unit join damage on damage.enduring_id = unit.damage_enduring_id where unit.starts <= 'time' and unit.ends = 'time' (This is not an actualy query from the database, I made it up to make clear what I mean. The the real database is a little more complex) Now I want to map it that way, so I can load all the damages which are valid at one time (starts <= wanted time <= ends) and that each of them has a Bag with all the attached units at that time (again starts <= wanted time <= ends). Is this possible within the mapping? Sorry if this is a stupid question, but I am pretty new to nhibernate and I have no clue how to do it. Thanks a lot for reading my post! Bye, Tobias

  • Partial Evaluation of ConstantExpression in ExpressionTreeVisitor

    - by Andrew Theken
    Hi all, I am not an Expression Tree master by any stretch of the imagination, what I have is code that looks like this: int external = 10; using(var session = new Session()) { session.Add(new Product { Name = "test1", Price = 20 }); session.Add(new Product {Name = "test", Price = 10}); var product = session.Products.Where(p => p.Price == external).FirstOrDefault(); Assert.Equal(10, product.Price); } Session implements all the IQueryProvider, IQueryable interfaces you'd come to expect from a LINQ Provider. When I execute the query, everything goes to plan until I read the ConstantExpression for "external", at which point, I am at a loss as to how to move forward because: //constant is ConstantExpression for "external" on the right side of the "p.Price == external" expression above. var t = constant.GetType(); //evaluates to class called "<>c__DisplayClass2" - with a member named "external" that has the value 10. The question is basically.. How can I just access the value of the member "external" - is there a way to accomplish this without using reflection? or am I cooked? What am I missing?

  • How to configure SQLite to run with NHibernate where assembly resolves System.Data.SQLite?

    - by Michael Hedgpeth
    I am using the latest NHibernate 2.1.0Beta2. I'm trying to unit test with SQLite and have the configuration set up as: Dictionary<string, string> properties = new Dictionary<string, string>(); properties.Add("connection.driver_class", "NHibernate.Driver.SQLite20Driver"); properties.Add("dialect", "NHibernate.Dialect.SQLiteDialect"); properties.Add("connection.provider", "NHibernate.Connection.DriverConnectionProvider"); properties.Add("query.substitutions", "true=1;false=0"); properties.Add("connection.connection_string", "Data Source=test.db;Version=3;New=True;"); properties.Add("proxyfactory.factory_class", "NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu"); configuration = new Configuration(); configuration.SetProperties(properties); When I try to run it, I get the following error: NHibernate.HibernateException: The IDbCommand and IDbConnection implementation in the assembly System.Data.SQLite could not be found. Ensure that the assembly System.Data.SQLite is located in the application directory or in the Global Assembly Cache. If the assembly is in the GAC, use <qualifyAssembly/> element in the application configuration file to specify the full name of the assembly. at NHibernate.Driver.ReflectionBasedDriver..ctor(String driverAssemblyName, String connectionTypeName, String commandTypeName) in c:\CSharp\NH\nhibernate\src\NHibernate\Driver\ReflectionBasedDriver.cs: line 26 at NHibernate.Driver.SQLite20Driver..ctor() in c:\CSharp\NH\nhibernate\src\NHibernate\Driver\SQLite20Driver.cs: line 28 So it looks like I need to reference the assembly directly. How would I do this so I don't get this error anymore? I downloaded the latest assembly from here: http://sourceforge.net/projects/sqlite-dotnet2.

  • Grails UrlMappings with .html

    - by Glennn
    I'm developing a Grails web application (mainly as a learning exercise). I have previously written some standard Grails apps, but in this case I wanted to try creating a controller that would intercept all requests (including static html) of the form: <a href="/testApp/testJsp.jsp">test 1</a> <a href="/testApp/testGsp.gsp">test 2</a> <a href="/testApp/testHtm.htm">test 3</a> <a href="/testApp/testHtml.html">test 4</a> The intent is to do some simple business logic (auditing) each time a user clicks a link. I know I could do this using a Filter (or a range of other methods), however I thought this should work too and wanted to do this using a Grails framework. I set up the Grail UrlMappings.groovy file to map all URLs of that form (/$myPathParam?) to a single controller: class UrlMappings { static mappings = { "/$controller/$action?/$id?"{ constraints { } } "/$path?" (controller: 'auditRecord', action: 'showPage') "500"(view:'/error') } } In that controller (in the appropriate "showPage" action) I've been printing out the path information, for example: def showPage = { println "params.path = " + params.path ... render(view: resultingView) } The results of the println in the showPage action for each of my four links are testJsp.jsp testGsp.gsp testHtm.htm testHtml Why is the last one "testHtml", not "testHtml.html"? In a previous (Stack Overflow query) Olexandr encountered this issue and was advised to simply concatenate the value of request.format - which, indeed, does return "html". However request.format also returns "html" for all four links. I'm interested in gaining an understanding of what Grails is doing and why. Is there some way to configure Grails so the params.path variable in the controller shows "testHtml.html" rather than stripping off the "html" extension? It doesn't seem to remove the extension for any other file type (including .htm). Is there a good reason it's doing this? I know that it is a bit unusual to use a controller for static html, but still would like to understand what's going on.

  • Translate SQL to OCL ?

    - by Roland Bengtsson
    I have a piece of SQL that I want to translate to OCL. I'm not good at SQL so I want to increase maintainability by this. We are using Interbase 2009, Delphi 2007 with Bold and modeldriven development. Now my hope is that someone here both speaks good SQL and OCL :-) The original SQL: Select Bold_Id, MessageId, ScaniaId, MessageType, MessageTime, Cancellation, ChassieNumber, UserFriendlyFormat, ReceivingOwner, Invalidated, InvalidationReason, (Select Parcel.MCurrentStates From Parcel Where ScaniaEdiSolMessage.ReceivingOwner = Parcel.Bold_Id) as ParcelState From ScaniaEdiSolMessage Where MessageType = 'IFTMBP' and not Exists (Select * From ScaniaEdiSolMessage EdiSolMsg Where EdiSolMsg.ChassieNumber = ScaniaEdiSolMessage.ChassieNumber and EdiSolMsg.ShipFromFinland = ScaniaEdiSolMessage.ShipFromFinland and EdiSolMsg.MessageType = 'IFTMBF') and invalidated = 0 Order By MessageTime desc After a small simplification: Select Bold_Id, (Select Parcel.MCurrentStates From Parcel where ScaniaEdiSolMessage.ReceivingOwner = Parcel.Bold_Id) From ScaniaEdiSolMessage Where MessageType = 'IFTMBP' and not Exists (Select * From ScaniaEdiSolMessage EdiSolMsg Where EdiSolMsg.ChassieNumber = ScaniaEdiSolMessage.ChassieNumber and EdiSolMsg.ShipFromFinland = ScaniaEdiSolMessage.ShipFromFinland and EdiSolMsg.MessageType = 'IFTMBF') and invalidated = 0 NOTE: There are 2 cases for MessageType, 'IFTMBP' and 'IFTMBF'. So the table to be listed is ScaniaEdiSolMessage. It has attributes like: MessageType: String ChassiNumber: String ShipFromFinland: Boolean Invalidated: Boolean It has also a link to table Parcel named ReceivingOwner with BoldId as key. So it seems like it list all rows of ScaniaEdiSolMessage and then have a subquery that also list all rows of ScaniaEdiSolMessage and name it EdiSolMsg. The it exclude almost all rows. In fact the query above give one hit from 28000 records. In OCL it is easy to list all instances: ScaniaEdiSolMessage.allinstances Also easy to filter rows by select for example: ScaniaEdiSolMessage.allinstances->select(shipFromFinland and not invalidated) But I do not understand how I should make a OCL to match the SQL above.

  • How do I efficiently write a "toggle database value" function in AJAX?

    - by AmbroseChapel
    Say I have a website which shows the user ten images and asks them to categorise each image by clicking on buttons. A button for "funny", a button for "scary", a button for "pretty" and so on. These buttons aren't exclusive. A picture can be both funny and scary. The user clicks the "funny" button. An AJAX request is sent off to the database to mark that image as funny. The "funny" button lights up, by assigning a class in the DOM to mark it as "on". But the user made a mistake. They meant to hit the next button over. They should click "funny" again to turn it off, right? At this point I'm not sure whats the most efficient way to proceed. The database knows that the "funny" flag is set, but it's inefficient to query the database every time a button is clicked to say, is this flag set or not, then go on with a second database call to toggle it. Should I infer the state of the database flag from the DOM, i.e. if that button has the class "on" then the flag must be set, and branch at that point? Or would it be better to have a data structure in Javascript in the page which duplicates the state of each image in the database, so that every time I set the database flag to true, I also set the value in the Javascript data to true and so on?

  • Something preventing default (explorer-style) CListCtrl jump to line behaviour

    - by andywebsdale
    I'm maintaining an MFC/COM/ATL 45-odd project solution originally written with VS6. I'm now using VS2008. I'm looking at a list control(vanilla CListCtrl) which doesn't behave as we think it should. Normally in an MFC list control you can press a key, (Q say) & selection will jump down to the 1st line beginning with 'Q' (like windows explorer). Does anyone have an idea as to why this might not happen? The styles/Extended styles are set the same as another control in the same project, which DOES work OK. Do I have to send my own message, or is there a flag, etc. that controls that functionality or what? Normally Google would supply the answer, but I haven't been able to frame my query correctly to come up with the relevant info this time. Here's the line from the .rc file for the CListCtrl that doesn't jump to a line on keypress: CONTROL "List1",IDC_BAL_LIST,"SysListView32",LVS_REPORT | LVS_SHOWSELALWAYS | WS_BORDER | WS_TABSTOP,0,73,493,230 And here's a line from the same .rc file showing a list control that does do that: CONTROL "List1",IDC_LIST1,"SysListView32",LVS_REPORT | LVS_SHOWSELALWAYS | WS_BORDER | WS_TABSTOP,1,38,501,219 As you can see, there's no obvious difference to the properties, so what program code would affect it?

  • Hadoop Map/Reduce - simple use example to do the following...

    - by alexeypro
    I have MySQL database, where I store the following BLOB (which contains JSON object) and ID (for this JSON object). JSON object contains a lot of different information. Say, "city:Los Angeles" and "state:California". There are about 500k of such records for now, but they are growing. And each JSON object is quite big. My goal is to do searches (real-time) in MySQL database. Say, I want to search for all JSON objects which have "state" to "California" and "city" to "San Francisco". I want to utilize Hadoop for the task. My idea is that there will be "job", which takes chunks of, say, 100 records (rows) from MySQL, verifies them according to the given search criteria, returns those (ID's) which qualify. Pros/cons? I understand that one might think that I should utilize simple SQL power for that, but the thing is that JSON object structure is pretty "heavy", if I put it as SQL schemas, there will be at least 3-5 tables joins, which (I tried, really) creates quite a headache, and building all the right indexes eats RAM faster than I one can think. ;-) And even then, every SQL query has to be analyzed to be utilizing the indexes, otherwise with full scan it literally is a pain. And with such structure we have the only way "up" is just with vertical scaling. But I am not sure it's the best option for me, as I see how JSON objects will grow (the data structure), and I see that the number of them will grow too. :-) Help? Can somebody point me to simple examples of how this can be done? Does it make sense at all? Am I missing something important? Thank you.

  • Dataflow Pipeline holding on to memory

    - by Jesse Carter
    I've created a Dataflow pipeline consisting of 4 blocks (which includes one optional block) which is responsible for receiving a query object from my application across HTTP and retrieving information from a database, doing an optional transform on that data, and then writing the information back in the HTTP response. In some testing I've done I've been pulling down a significant amount of data from the database (570 thousand rows) which are stored in a List object and passed between the different blocks and it seems like even after the final block has been completed the memory isn't being released. Ram usage in Task Manager will spike up to over 2 GB and I can observe several large spikes as the List hits each block. The signatures for my blocks look like this: private TransformBlock<HttpListenerContext, Tuple<HttpListenerContext, QueryObject>> m_ParseHttpRequest; private TransformBlock<Tuple<HttpListenerContext, QueryObject>, Tuple<HttpListenerContext, QueryObject, List<string>>> m_RetrieveDatabaseResults; private TransformBlock<Tuple<HttpListenerContext, QueryObject, List<string>>, Tuple<HttpListenerContext, QueryObject, List<string>>> m_ConvertResults; private ActionBlock<Tuple<HttpListenerContext, QueryObject, List<string>>> m_ReturnHttpResponse; They are linked as follows: m_ParseHttpRequest.LinkTo(m_RetrieveDatabaseResults); m_RetrieveDatabaseResults.LinkTo(m_ConvertResults, tuple => tuple.Item2 is QueryObjectA); m_RetrieveDatabaseResults.LinkTo(m_ReturnHttpResponse, tuple => tuple.Item2 is QueryObjectB); m_ConvertResults.LinkTo(m_ReturnHttpResponse); Is it possible that I can set up the pipeline such that once each block is done with the list they no longer need to hold on to it as well as once the entire pipeline is completed that the memory is released?

  • How to adjust size of programatically created Bitmap to match text drawn on it?

    - by TooFat
    I have the following .ashx page that takes some query string parameters and returns a bitmap with the specified text written on it. The problem I have is that I am currently just manually setting the initial size of the bitmap at 100 X 100 when what I really want is to have the bitmap be just big enough to include all the text that was written to it. How can I do this? public void ProcessRequest (HttpContext context) { context.Response.ContentType = "image/png"; string text = context.Request.QueryString["Text"]; //set FontName string fontName; if (context.Request.QueryString["FontName"] != null) { fontName = context.Request.QueryString["FontName"]; } else { fontName = "Arial"; } //Set FontSize int fontEms; if (context.Request.QueryString["FontSize"] != null) { string fontSize = context.Request.QueryString["FontSize"]; fontEms = Int32.Parse(fontSize); } else { fontEms = 12; } //Set Font Color System.Drawing.Color color; if (context.Request.QueryString["FontColor"] != null) { string fontColor = context.Request.QueryString["FontColor"]; color = System.Drawing.ColorTranslator.FromHtml(fontColor); context.Response.Write(color.ToString()); } else { color = System.Drawing.Color.Red; } using (System.Drawing.Text.PrivateFontCollection fnts = new System.Drawing.Text.PrivateFontCollection()) using (System.Drawing.FontFamily fntfam = new System.Drawing.FontFamily(fontName)) using (System.Drawing.SolidBrush brush = new System.Drawing.SolidBrush(color)) using (System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(100, 100)) { using (System.Drawing.Font fnt = new System.Drawing.Font(fntfam, fontEms)) { fnts.AddFontFile(System.IO.Path.Combine(@"C:\Development\Fonts\", fontName)); System.Drawing.Graphics graph = System.Drawing.Graphics.FromImage(bmp); graph.DrawString(text, fnt, brush, new System.Drawing.Point(0, 0)); string imgPath = System.IO.Path.Combine(@"C:\Development\MyPath\Images\Text", System.IO.Path.GetRandomFileName()); bmp.Save(imgPath); context.Response.WriteFile(imgPath); } } }

  • Can a large transaction log cause cpu hikes to occur

    - by Simon Rigby
    Hello all, I have a client with a very large database on Sql Server 2005. The total space allocated to the db is 15Gb with roughly 5Gb to the db and 10 Gb to the transaction log. Just recently a web application that is connecting to that db is timing out. I have traced the actions on the web page and examined the queries that execute whilst these web operation are performed. There is nothing untoward in the execution plan. The query itself used multiple joins but completes very quickly. However, the db server's CPU hikes to 100% for a few seconds. The issue occurs when several simultaneous users are working on the system (when I say multiple .. read about 5). Under this timeouts start to occur. I suppose my question is, can a large transaction log cause issues with CPU performance? There is about 12Gb of free space on the disk currently. The configuration is a little out of my hands but the db and log are both on the same physical disk. I appreciate that the log file is massive and needs attending to, but I'm just looking for a heads up as to whether this may cause CPU spikes (ie trying to find the correlation). The timeouts are a recent thing and this app has been responsive for a few years (ie its a recent manifestation). Many Thanks,
