  • Linq Paging - How to incorporate total record count

    - by Billy Logan
    Hello everyone, I am trying to figure out the best way of getting the record count will incorporating paging. I need this value to figure out the total page count given a page size and a few other variables. This is what i have so far which takes in the starting row and the page size using the skip and take statements. promotionInfo = (from p in matches orderby p.PROMOTION_NM descending select p).Skip(startRow).Take(pageSize).ToList(); I know i could run another query, but figured there may be another way of achieving this count without having to run the query twice. Thanks in advance, Billy

  • My simple PHP is outputting wrong things.

    - by Sergio Tapia
    EDIT: I forgot to add semi colons. Now there is another problems. I'm getting a error: Parse error: syntax error, unexpected T_STRING in C:\xampp\htdocs\useraccess.php on line 12 It outputs: 0){ echo 'si'; } ?> When it should only output 'si' in the body. Here's the code: <html> <head> </head> <body> <? $user = mysql_real_escape_string($_GET["u"]) $pass = mysql_real_escape_string($_GET["p"]) $query = "SELECT * FROM usario WHERE username = '$user' AND password = '$pass'" mysql_connect(localhost, "sergio", "123"); @mysql_select_db("multas") or die( "Unable to select database"); $result=mysql_query($query); if(mysql_numrows($result) > 0){ echo 'si'; } ?> </body> </html>

  • Why do we keep using CSV?

    - by Stephen
    Why do we keep using CSV? I recently made a shift to working the health domain and despite the wonderful work in data transfer standards, all data transfer is in CSV, both for reporting to external organisations, and for data migrations when implementing new systems. Unfortunately the use of CSV is the cause of the endless repetition of the same stupid errors, with the same waste of developer time. (bad escaping, failing to handle null fields etc.) I know we can do better, and anything between JSON and XML (depending on the instance) would be fine. (Most of the time this is data going from one MS SQLserver 2005 to another!) I feel as if each time I see this happening I am literally watching one developer waste anothers time. So why do we keep shafting each other? When will we stop?

  • How to get MAX value of a version-number (varchar) column in T-SQL

    - by Ogre Psalm33
    I have a table defined like this: Column: Version Message Type: varchar(20) varchar(100) ---------------------------------- Row 1: 2.2.6 Message 1 Row 2: 2.2.7 Message 2 Row 3: 2.2.12 Message 3 Row 4: 2.3.9 Message 4 Row 5: 2.3.15 Message 5 I want to write a T-Sql query that will get message for the MAX version number, where the "Version" column represents a software version number. I.e., 2.2.12 is greater than 2.2.7, and 2.3.15 is greater than 2.3.9, etc. Unfortunately, I can't think of an easy way to do that without using CHARINDEX or some complicated other split-like logic. Running this query: SELECT MAX(Version) FROM my_table will yield the erroneous result: 2.3.9 When it should really be 2.3.15. Any bright ideas that don't get too complex?

  • Using LINQ Group By to return new XElements

    - by Jon
    I have the following code and got myself confused: I have a query that returns a set of records that have been identified as duplicates and I then want to create a XElement for each one. This should be done in one query I think but I'm now lost. var f = (from x in MyDocument.Descendants("RECORD") where itemsThatWasDuplicated.Contains((int)x.Element("DOCUMENTID")) group x by x.Element("DOCUMENTID").Value into g let item = g.Skip(1) //Ignore first as that is the valid one select item ); var errorQuery = (from x in f let sequenceNumber = x.Element("DOCUMENTID").Value let detail = "Sequence number " + sequenceNumber + " was read more than once" select new XElement("ERROR", new XElement("DATETIME", time), new XElement("DETAIL", detail), new XAttribute("TYPE", "DUP"), new XElement("ID", x.Element("ID").Value) ) );

  • SQLSTATE[HY000]: General error: 5 Out of memory (Needed 4194092 bytes)

    - by Jon Reeks
    Hi I'm receiving the following error on my shared hosting box: SQLSTATE[HY000]: General error: 5 Out of memory (Needed 4194092 bytes) This error is only triggered on a specific page. I guess this indicates that I am reaching the upper limit of the 64MB allocated to me in my current MySQL environment. Does this mean that a single query is going over (returning) 64MB of data? If so, i guess i can just track down and tune that specific query? Or isnt that the correct approach? Thanks Jon

  • AJAX 4 no ASP.NET 4 Web Application

    - by renatohaddad
    Andei fazendo uns testes no AJAX Control Toolkit 4 que deverá ser usado com o ASP.NET 4 no Visual Studio .NET 2010 e confesso que gostei muito. O link para download é http://www.asp.net/ajaxlibrary/act.ashx e todas as instruções constam no site. Notei que há diversos controles novos e um que me chamou a atenção foi o de Upload assíncrono para controlar os uploads de arquivos para o server. Vale a pena estudar um pouco estas novidades. Para quem já usava o AJAX no ASP.NET 3.5, a idéia do Toolkit é igual, exceto a adição de novos controles. Com o AJAX vc pode mudar todo o comportamento da sua aplicação WEB, requisições no server passam a ser menos frequentes, o layout ajuda e muito com os controles do AJAX. Nativamente no VS 2010 já há o AJAX que a MS suporta nativamente (ScriptManager, UpdatePanel, UpdateProgress, etc), mas vale a pena implementar alguns controles do Toolkit. Bons estudos!

  • A PHP design pattern for the model part [PHP Zend Framework]

    - by Matthieu
    I have a PHP MVC application using Zend Framework. As presented in the quickstart, I use 3 layers for the model part : Model (business logic) Data mapper Table data gateway (or data access object, i.e. one class per SQL table) The model is UML designed and totally independent of the DB. My problem is : I can't have multiple instances of the same "instance/record". For example : if I get, for example, the user "Chuck Norris" with id=5, this will create a new model instance wich members will be filled by the data mapper (the data mapper query the table data gateway that query the DB). Then, if I change the name to "Duck Norras", don't save it in DB right away, and re-load the same user in another variable, I have "synchronisation" problems... (different instances for the same "record") Right now, I use the Multiton pattern : like Singleton, but multiple instances indexed by a key (wich is the user ID in our example). But this is complicating my developpement a lot, and my testings too. How to do it right ?

  • using WP_Query with custom SQL in wordpress

    - by Matt Facer
    Hi. I am writing a plugin for wordpress and I want to create my own search. I have tried to alter the wordpress search, but what I am doing is very specific with the SQL query. I am comparing lat and long coordinates and getting posts based on that. I can display posts by using the standard wpdb query, but then I don't get the other features like paging. I'd like to be able to use my SQL statement with the WP_Query function. If I'm right in thinking, I should then be able to use the paging and other features which come from the $posts global variable. Is this right?? I've googled for hours but can't find anything for plugins outside of using args to select categories etc. I simply need to send a complete SQL command - nothing else. Many thanks....

  • How to register a QueryExecuterFactory in jasper reports in java

    - by Bosso
    Hi, I implemented JRQueryExecuter and want to use it in a report. Using iReport I managed to register and use the executer. Now I want to use it in a java application, but I can't find any resources how to register the factory. I thought it's enough to have the implementation in the classpath, but I get the following exception: Caused by: net.sf.jasperreports.engine.JRException: No query executer factory class registered for tmql queries. at net.sf.jasperreports.engine.query.DefaultQueryExecuterFactoryBundle.getQueryExecuterFactory(DefaultQueryExecuterFactoryBundle.java:80) at net.sf.jasperreports.engine.util.JRQueryExecuterUtils.getQueryExecuterFactory(JRQueryExecuterUtils.java:57) at net.sf.jasperreports.engine.design.JRDesignDataset.queryLanguageChanged(JRDesignDataset.java:1006) Can anybody give me a hint? regards Hannes

  • SQL datasource for gridview

    - by Karsten
    Hi I want to use a gridview with sorting and paging to display data from an SQL server, the query uses 3 joins and the full text search containstable. The from part of the query uses all 3 tables in the join. What is the best way to do this? I can think of a stored procedure, SQL directly in the SQLDataSource and creating a view in the database. I want good performance and would like to leverage the automatic sorting and paging features of the gridview as much as possible.

  • Querying a Cassandra column family for rows that have not been updated in X days

    - by knorv
    I'm moving an existing MySQL based application over to Cassandra. So far finding the equivalent Cassandra data model has been quite easy, but I've stumbled on the following problem for which I'd appreciate some input: Consider a MySQL table holding millions of entities: CREATE TABLE entities ( id INT AUTO_INCREMENT NOT NULL, entity_information VARCHAR(...), entity_last_updated DATETIME, PRIMARY KEY (id), KEY (entity_last_updated) ); The table is regularly queried for entities that need to be updated: SELECT id FROM entities WHERE entity_last_updated IS NULL OR entity_last_updated < DATE_ADD(NOW(), INTERVAL -7*24 HOUR) ORDER BY entity_last_updated ASC; The entities returned by this queries are then updated using the following query: UPDATE entities SET entity_information = ?, entity_last_updated = NOW() WHERE id = ?; What would be the corresponding Cassandra data model that would allow me to store the given information and effectively query the entities table for entities that need to be updated (that is: entities that have not been updated in the last seven days)?

  • Best way to compare contents of two tables in Teradata?

    - by Cade Roux
    When you need to compare two tables to see what the differences are, are there any tools or shortcuts you use, or do you handcode the SQL to compare the two tables? Background: In my SQL Server environment, I created a stored procedure which inspects the metadata of the two tables/views, creates a query (as dynamic sql) which joins the two tables on the specified key columns, and compares data in the compare columns, reporting key differences and data differences. The query can either be printed and modified/copied or just excecuted as is. We are not allowed to create stored procedures in our Teradata environment, unfortunately.

  • Problem using Hibernate-Search

    - by KCore
    Hi, I am using hibernate search for my application. It is well configured and running perfectly till some time back, when it stopped working suddenly. The reason according to me being the number of my model (bean) classes. I have some 90 classes, which I add to my configuration, while building my Hibernate Configuration. When, I disable hibernate search (remove the search annotations and use Configuration instead of AnnotationsConfiguration), I try to start my application, it Works fine. But,the same app when I enable search, it just hangs up. I tried debugging and found the exact place where it hangs. After adding all the class to my AnnotationsConfiguration object, when I say cfg.buildSessionfactory(), It never comes out of that statement. (I have waited for hours!!!) Also when I decrease the number of my model classes (like say to half i.e. 50) it comes out of that statement and the application works fine.. Can Someone tell why is this happening?? My versions of hibernate are: hibernate-core-3.3.1.GA.jar hibernate-annotations-3.4.0.GA.jar hibernate-commons-annotations-3.1.0.GA.jar hibernate-search-3.1.0.GA.jar Also if need to avoid using AnnotationsConfiguration, I read that I need to configure the search event listeners explicitly.. can anyone list all the neccessary listeners and their respective classes? (I tried the standard ones given in Hibernate Search books, but they give me ClassNotFound exception and I have all the neccesarty libs in classpath) Here are the last few lines of hibernate trace I managed to pull : 16:09:32,814 INFO AnnotationConfiguration:369 -

  • Use Any() and Count() in Dynamic Linq

    - by ArpanDesai
    I am trying to write dynamic Linq Library query to fetch record on condition, Customers who has order count is greater than 3 and ShipVia field equal 2. Below is my syntax what i have tried. object[] objArr = new object[10]; objArr[0] = 1; IQueryable<Customer> test = db.Customers.Where("Orders.Count(ShipVia=2)", objArr); and IQueryable<Customer> test = db.Customers.Where("Orders.Any(ShipVia=2).Count()", objArr); But both are not working. In second query Any returns true so it won't work with Count. Suggest me a way to implement this.

  • MTU mismatch between GetIfEntry and netsh

    - by ChrisJ
    I'm working on pseudo-transport layer software that runs over UDP, providing reliable connection-oriented transmission, as an alternative to TCP. In order to maximize network efficiency, we query the MTU of the "best" network adapter upon initialization. MIB_IFROW row = {0}; row.dwIndex = dwBestIfIndex; dwRes = GetIfEntry(&row); Searching online I found that you can use the following netsh commands to query for this same value, from a command prompt (not a C++ API) netsh interface ipv4 show interfaces netsh interface ipv4 show subinterfaces The troubling issue is that while row.dwMtu may be set to 1500, snooping the network traffic on the sending laptop shows that our packets are fragmented into 1300 byte packets. netsh also reports that the MTU is 1300. Clearly the value reported by netsh command is the actual used values. Anyone know what API I can call to get the same values as netsh?

  • Inserting the record into Database through JPA

    - by vinay123
    In my code I am using JSF - Front end , EJB-Middile Tier and JPA connect to DB.Calling the EJB using the Webservices.Using MySQL as DAtabase. I have created the Voter table in which I need to insert the record. I ma passing the values from the JSF to EJB, it is working.I have created JPA controller class (which automatcally generates the persistence code based on the data base classes) Ex: getting the entity manager etc., em = getEntityManager(); em.getTransaction().begin(); em.persist(voter); em.getTransaction().commit(); I have created the named query also: @NamedQuery(name = "Voter.insertRecord", query = "INSERT INTO Voter v values v.voterID = :voterID,v.password = :password,v.partSSN = :partSSN, v.address = :address, v.zipCode = :zipCode,v.ssn = :ssn, v.vFirstName = :vFirstName,v.vLastName = :vLastName,v.dob = :dob"), But still not able to insert the record?

  • Accessing unbound DetailsView cell values when Detailsview DefaultMode is Edit

    - by Nickson
    i have a DetailsView that is populated by a Linq to Entities query. Example query is below. Dim Record = From L In db.MyRecords _ Where L.RecordID = 100 _ Select ID = L.RecordID, L.column1, L.column2, L.column3, L.column4 DetailsView2.DataSource = Record DetailsView2.DataBind() The defaultMode for the DetailsView is Edit. Now if this Detailsview was bound to a datasource control, i would convert a column to a templateColumn and programatically access cell values like so Dim NameTextBox As System.Web.UI.WebControls.TextBox = CType(DetailsView2.Rows(1).Cells(1).FindControl("TextBox1"), System.Web.UI.WebControls.TextBox) such that i can then say NameTextBox.Text to get the Name value. But the problem i have is, with this detailsview which is unbound, i have no column at design time to convert to a template, and yet i want to access its cell values. help is appreciated.

  • ruby on rails named scope implementation

    - by Engwan
    From the book Agile Web Development With Rails class Order < ActiveRecord::Base named_scope :last_n_days, lambda { |days| {:conditions => ['updated < ?' , days] } } named_scope :checks, :conditions => {:pay_type => :check} end The statement orders = Orders.checks.last_n_days(7) will result to only one query to the database. How does rails implement this? I'm new to Ruby and I'm wondering if there's a special construct that allows this to happen. To be able to chain methods like that, the functions generated by named_scope must be returning themselves or an object than can be scoped further. But how does Ruby know that it is the last function call and that it should query the database now? I ask this because the statement above actually queries the database and not just returns an SQL statement that results from chaining.

  • GetVirtualPath not making any sense.

    - by HeavyWave
    Can anyone explain why this code with the given routes returns the first route? routes.MapRoute(null, "user/approve", new { controller = "Users", action = "Approve" }), routes.MapRoute(null, "user/{username}", new { controller = "Users", action = "Profile" }), routes.MapRoute(null, "user/{username}/{action}", new { controller = "Users" }), routes.MapRoute(null, "user/{username}/{action}/{id}", new { controller = "Users" }), routes.MapRoute(null, "search/{query}", new { controller = "Artists", action = "Search", page = 1 }), routes.MapRoute(null, "search/{query}/{page}", new { controller = "Artists", action = "Search" }), routes.MapRoute(null, "music", new { controller = "Artists", action = "Index", page = 1 }), routes.MapRoute(null, "music/page/{page}", new { controller = "Artists", action = "Index" }) var pageLinkValueDictionary = new RouteValueDictionary(this.linkWithoutPageValuesDictionary); pageLinkValueDictionary.Add("page", pageNumber); var virtualPathData = RouteTable.Routes.GetVirtualPath(this.viewContext.RequestContext, pageLinkValueDictionary); Here GetVirtualPath always returns user/approve, although there is no {page} parameter in the route. Furthermore, everything works as expected without the first route. I have found this link http://www.codeplex.com/aspnet/WorkItem/View.aspx?WorkItemId=2033 but it wasn't very helpful. It looks like GetVirtualPath was not implemented with large collections of routes in mind. I am using ASP.Net MVC 1.0.

  • How does Windows LIve ID work?

    - by Morgan Cheng
    I happens to find this nice article explaining how OpenID works. Clearly, OpenID consumer and OpenID server transfer information through URL query string. I'm wondering how Live ID accomplish similar functionality. It seems the info is not exchanged through query string in URL. And, since Live ID login server have different domain name from consumer domain, it is not applicable to transfer info through cookie. I tried to google tutorial of Live ID, but the result is full of jargon and hard to understand. Is there any easy-to-understand tutorial about How Live ID works?

  • Accurately display upload progress in Silverilght upload

    - by Matt
    I'm trying to debug a file upload / download issue I'm having. I've got a Silverlight file uploader, and to transmit the files I make use of the HttpWebRequest class. So I create a connection to my file upload handler on the server and begin transmitting. While a file uploads I keep track of total bytes written to the RequestStream so I can figure out a percentage. Now working at home I've got a rather slow connection, and I think Silverlight, or the browser, is lying to me. It seems that my upload progress logic is inaccurate. When I do multiple file uploads (24 images of 3-6mb big in my testing), the logic reports the files finish uploading but I believe that it only reflects the progress of written bytes to the RequestStream, not the actual amount of bytes uploaded. What is the most accurate way to measure upload progress. Here's the logic I'm using. public void Upload() { if( _TargetFile != null ) { Status = FileUploadStatus.Uploading; Abort = false; long diff = _TargetFile.Length - BytesUploaded; UriBuilder ub = new UriBuilder( App.siteUrl + "upload.ashx" ); bool complete = diff <= ChunkSize; ub.Query = string.Format( "{3}name={0}&StartByte={1}&Complete={2}", fileName, BytesUploaded, complete, string.IsNullOrEmpty( ub.Query ) ? "" : ub.Query.Remove( 0, 1 ) + "&" ); HttpWebRequest webrequest = ( HttpWebRequest ) WebRequest.Create( ub.Uri ); webrequest.Method = "POST"; webrequest.BeginGetRequestStream( WriteCallback, webrequest ); } } private void WriteCallback( IAsyncResult asynchronousResult ) { HttpWebRequest webrequest = ( HttpWebRequest ) asynchronousResult.AsyncState; // End the operation. Stream requestStream = webrequest.EndGetRequestStream( asynchronousResult ); byte[] buffer = new Byte[ 4096 ]; int bytesRead = 0; int tempTotal = 0; Stream fileStream = _TargetFile.OpenRead(); fileStream.Position = BytesUploaded; while( ( bytesRead = fileStream.Read( buffer, 0, buffer.Length ) ) != 0 && tempTotal + bytesRead < ChunkSize && !Abort ) { requestStream.Write( buffer, 0, bytesRead ); requestStream.Flush(); BytesUploaded += bytesRead; tempTotal += bytesRead; int percent = ( int ) ( ( BytesUploaded / ( double ) _TargetFile.Length ) * 100 ); UploadPercent = percent; if( UploadProgressChanged != null ) { UploadProgressChangedEventArgs args = new UploadProgressChangedEventArgs( percent, bytesRead, BytesUploaded, _TargetFile.Length, _TargetFile.Name ); SmartDispatcher.BeginInvoke( () => UploadProgressChanged( this, args ) ); } } //} // only close the stream if it came from the file, don't close resizestream so we don't have to resize it over again. fileStream.Close(); requestStream.Close(); webrequest.BeginGetResponse( ReadCallback, webrequest ); }
