  • solr JOIN query

    - by Sfairas
    I need to run a JOIN query on a solr index. I've got two xmls that I have indexed, person.xml and subject.xml. Person: <doc> <field name="id">P39126</field> <field name="family">Smith</field> <field name="given">John</field> <field name="subject">S1276</field> <field name="subject">S1312</field> </doc> Subject: <doc> <field name="id">S1276</field> <field name="topic">Abnormalities, Human</field> </doc> I need to only display information from the person doc but each query should match fields in both person and subject. In the case the query matches only the subject doc I need to display all docs from the person that have a matching id. Is this possible to do without running two seperate queries? Something like a JOIN query would do the job. Any help?

  • Client-Server Networking Between PHP Client and Java Server

    - by Muhammad Yasir
    Hi there, I have a university project which is already 99% completed. It consists of two parts-website (PHP) and desktop (Java). People have their accounts on the website and they wish to query different information regarding their accounts. They send an SMS which is received by desktop application which queries database of website (MySQL) and sends the reply accordingly. This part is working superbly. The problem is that some times website wishes to instruct the desktop application to send a specific SMS to a particular number. Apparently there seems no way other than putting all the load to the DB server... This is how I made it work. Website puts SMS jobs in a specific table. Java application polls this table again and again and if it finds a job, it executes it. Even this part is working correctly but unfortunately it is not acceptable by my university to poll the DB like this. :( The other approach I could think of is to use client-server one. I tried making Java server and its PHP client. So that whenever an SMS is to be sent, the website opens a socket connection to desktop application and sends two strings (cell # and SMS message). Unfortunately I am unable to do this. I was successfully to make a Java server which works fine when connected by a Java client, similarly my PHP client connects correctly to a PHP server, but when I try to cross them, they start hating each other... PHP shows no error but Java gives StreamCorruptedException when it tries to read header of input stream. Could someone please tell what I can try to make PHP client and Java server work together? Or if the said purpose can be achieved by another means, how? Regards, Yasir

  • Focussing on Style Sheets and Cross Browser Compatibility.

    - by Sam
    Hello everyone, Let me begin this topic by explaining my background experience with web design. I have always been more of a back end programmer, with PHP and SQL and things. However I do have a shallow background with HTML and CSS. The problem is, I don't know it all. What I do know is, when it comes to designing (not back end dirty work) I understand basic CSS properties and I also understand HTML and I can usually throw together a sloppy web page with the two and a couple bazillion DIV tags. Anyways.. The problem I always have encountered is that when I design a website in a browser such as IE7 (and then it looks perfect on IE7), and then look at it on IE8 or IE6 or Mozilla (etc.) it gets all spacey and ugly and looks totally different than the way it should look on IE7. Question one: Basically, what I am asking everyone is what route should I take to learn how to properly build the website? Build as in put it togehter with CSS standards and HTML standards that will make my site look the same on every brwoser. (Not only learning standards but where can I learn to properly write my code?) Where is a strong free resource I can use to learn how to these things? Question two: How do I properly code my website? Do I use all external style sheets to make dynamic page design simplistic or do I hard code some things into the DIV tags on each page? What is proper? Oh, and if anyone has any tutorials on how to properly design a complete layout feel free to throw it in a response somewhere. Thank you for taking the time to read my questions, and hopefully you will understand what I am trying to get out to everyone. I need to get on the right route of the designing side of web programming so that I will know how to create successful websites in the future. Thank you, Sam Pardee

  • NHibernate query with Projections.Cast to DateTime

    - by stiank81
    I'm experimenting with using a string for storing different kind of data types in a database. When I do queries I need to cast the strings to the right type in the query itself. I'm using .Net with NHibernate, and was glad to learn that there exists functionality for this. Consider the simple class: public class Foo { public string Text { get; set; } } I successfully use Projections.Cast to cast to numeric values, e.g. the following query correctly returns all Foos with an interger stored as int - between 1-10. var result = Session.CreateCriteria<Foo>() .Add(Restrictions.Between(Projections.Cast(NHibernateUtil.Int32, Projections.Property("Text")), 1, 10)) .List<Foo>(); Now if I try using this for DateTime I'm not able to make it work no matter what I try. Why?! var date = new DateTime(2010, 5, 21, 11, 30, 00); AddFooToDb(new Foo { Text = date.ToString() } ); // Will add it to the database... var result = Session .CreateCriteria<Foo>() .Add(Restrictions.Eq(Projections.Cast(NHibernateUtil.DateTime, Projections.Property("Text")), date)) .List<Foo>();

  • EF4 querying from parent to grandchildren

    - by Hans Kesting
    I have a model withs Parents, Children and Grandchildren, in a many-to-many relationship. Using this article I created POCO classes that work fine, except for one thing I can't yet figure out. When I query the Parents or Children directly using LINQ, the SQL reflects the LINQ query (a .Count() executes a COUNT in the database and so on) - fine. The Parent class has a Children property, to access it's children. But (and now for the problem) this doesn't expose an IQueryable interface but an ICollection. So when I access the Children property on a particular parent all the Parent's Children are read. Even worse, when I access the Grandchildren (theParent.Children.SelectMany(child => child.GrandChildren).Count()) then for each and every child a separate request is issued to select all data of it's grandchildren. That's a lot of separate queries! Changing the type of the Children property from ICollection to IQueryable doesn't solve this. Apart from missing methods I need, like Add() and Remove(), EF just doesn't recognize the navigation property then. Are there correct ways (as in: low database interaction) of querying through children (and what are they)? Or is this just not possible?

  • Cannot rollback ransaction with Entity Framework

    - by Luca
    I have to do queries on uncommitted changes and I tried to use transactions, but I found that it do not work if there are exceptions. I made a simple example to reproduce the problem. I have a database with only one table called "Tabella" and the table has two fields: "ID" is a autogenerated integer, and "Valore" is an integer with a Unique constraint. Then I try to run this code: using (TransactionScope scope = new TransactionScope()) { Db1Container db1 = new Db1Container(); try { db1.AddToTabella(new Tabella() { Valore = 1 }); db1.SaveChanges(); } catch { } try { db1.AddToTabella(new Tabella() { Valore = 1 }); db1.SaveChanges(); //Unique constraint is violated here and an exception is thrown } catch { } try { db1.AddToTabella(new Tabella() { Valore = 2 }); db1.SaveChanges(); } catch { } //scope.Complete(); //NEVER called } //here everything should be rolled back Now if I look into the database it should contain no records because the transaction should rollback, instead I find two records!!!! One with Valore=1 and one with Valore=2. I am missing something? It looks like the second call to SaveChanges method rollback its own changes and "deletes" the transaction, then the third call to SaveChanges commits the changes of the first and the third insert (at this point it is like the transaction not exists). I also tried to use SaveChanges(false) method (even without calling AcceptAllChanges method), but with no success: I have the same behaviour. I do not want the transaction to be rolled back automatically by SaveChanges, because I want to correct the errors (for example by user interaction in the catch statement) and make a retry. Can someone help me with this? It seems like a "bug", and it is giving me a really big headache...

  • How to get current Joomla user with external PHP script

    - by Joey Adams
    I have a couple PHP scripts used for AJAX queries, but I want them to be able to operate under the umbrella of Joomla's authentication system. Is the following safe? Are there any unnecessary lines? joomla-auth.php (located in the same directory as Joomla's index.php): <?php define( '_JEXEC', 1 ); define('JPATH_BASE', dirname(__FILE__)); define( 'DS', DIRECTORY_SEPARATOR ); require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' ); require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' ); /* Create the Application */ $mainframe =& JFactory::getApplication('site'); /* Make sure we are logged in at all. */ if (JFactory::getUser()->id == 0) die("Access denied: login required."); ?> test.php: <?php include 'joomla-auth.php'; echo 'Logged in as "' .

  • ICollectionView.SortDescriptions sort does not work if underlying DataTable has zero rows

    - by BigBlondeViking
    We have a WPF app that has a DataGrid inside a ListView. private DataTable table_; We do a bunch or dynamic column generation ( depending on the report we are showing ) We then do the a query and fill the DataTable row by row, this query may or may not have data.( not the problem, an empty grid is expected ) We set the ListView's ItemsSource to the DefaultView of the DataTable. lv.ItemsSource = table_.DefaultView; We then (looking at the user's pass usage of the app, set the sort on the column) Sort Method below: private void Sort(string sortBy, ListSortDirection direction) { ICollectionView dataView = CollectionViewSource.GetDefaultView(lv.ItemsSource); dataView.SortDescriptions.Clear(); var sd = new SortDescription(sortBy, direction); dataView.SortDescriptions.Add(sd); dataView.Refresh(); } In the Zero DataTable rows scenario, the sort does not "hold"? and if we dynamically add rows they will not be in sorted order. If the DataTable has at-least 1 row when the sort is applied, and we dynamically add rows to the DataTable, the rows com in sorted correctly. I have built a standalone app that replicate this... It is an annoyance and I can add a check to see if the DataTable was empty, and re-apply the sort... Anyone know whats going on here, and am I doing something wrong? FYI: What we based this off if comes from the MSDN as well: http://msdn.microsoft.com/en-us/library/ms745786.aspx

  • Extract a subset of XML file using XSL

    I have this XML file: <Response> <errorCode>error Code</errorCode> <errorMessage>msg</errorMessage> <ResponseParameters> <className> <attribute1>a</attribute1> <attribute2>b</attribute2> </className> </ResponseParameters> </Response> And I want the output to be: <className> <attribute1>a</attribute1> <attribute2>b</attribute2> </className> My current XSL file is including also "ResponseParameters" tag, which I do not want.

  • Force float left with no line break no matter what

    - by Tesserex
    I'm guessing this isn't possible, but here goes. I have two tables, and I'm trying to get them to sit side-by-side so that they look like one table. The reason for this, instead of using one larger table, is that the data in the second table needs to be handled on a column basis, not row basis, for performance reasons like caching and AJAX-fetching data. So rather than have to reload the whole table for a single column, I decided to break the column out into a separate table, but have it visually seem like a single table. I can't find a way to forcibly put the second table next to the first. I can float them, but when the first table is too wide, the second one breaks to the next line. Here's the kicker: the width of the first table is dynamic. So I can't just set a huge width to their container. Well, I could set a huge width, like 1000%, but then I have a huge ugly horizontal scroll bar. So is there any way to tell the second table "Stay on that same line, no matter what! And line up right next to the previous element please!"

  • Objective-C : Fowler–Noll–Vo (FNV) Hash implementation

    - by Dough
    Hi ! I have a HTTP connector in my iPhone project and queries must have a parameter set from the username using the Fowler–Noll–Vo (FNV) Hash. I have a Java implementation working at this time, this is the code : long fnv_prime = 0x811C9DC5; long hash = 0; for(int i = 0; i < str.length(); i++) { hash *= fnv_prime; hash ^= str.charAt(i); } Now on the iPhone side, I did this : int64_t fnv_prime = 0x811C9DC5; int64_T hash = 0; for (int i=0; i < [myString length]; i++) { hash *= fnv_prime; hash ^= [myString characterAtIndex:i]; } This script doesn't give me the same result has the Java one. In first loop, I get this : hash = 0 hash = 100 (first letter is "d") hash = 1865261300 (for hash = 100 and fnv_prime = -2128831035 like in Java) Do someone see something I'm missing ? Thanks in advance for the help !

  • Legit? Two foreign keys referencing the same primary key.

    - by Ryan
    Hi All, I'm a web developer and have recently started a project with a company. Currently, I'm working with their DBA on getting the schema laid out for the site, and we've come to a disagreement regarding the design on a couple tables, and I'd like some opinions on the matter. Basically, we are working on a site that will implement a "friends" network. All users of the site will be contained in a table tblUsers with (PersonID int identity PK, etc). What I am wanting to do is to create a second table, tblNetwork, that will hold all of the relationships between users, with (NetworkID int identity PK, Owners_PersonID int FK, Friends_PersonID int FK, etc). Or conversely, remove the NetworkID, and have both the Owners_PersonID and Friends_PersonID shared as the Primary key. This is where the DBA has his problem. Saying that "he would only implement this kind of architecture in a data warehousing schema, and not for a website, and this is just another example of web developers trying to take the easy way out." Now obviously, his remark was a bit inflammatory, and that have helped motivate me to find an suitable answer, but more so, I'd just like to know how to do it right. I've been developing databases and programming for over 10 years, have worked with some top-notch minds, and have never heard this kind of argument. What the DBA is wanting to do is instead of storing both the Owners_PersonId and Friends_PersonId in the same table, is to create a third table tblFriends to store the Friends_PersonId, and have the tblNetwork have (NetworkID int identity PK, Owner_PersonID int FK, FriendsID int FK(from TBLFriends)). All that tblFriends would house would be (FriendsID int identity PK, Friends_PersonID(related back to Persons)). To me, creating the third table is just excessive in nature, and does nothing but create an alias for the Friends_PersonID, and cause me to have to add (what I view as unneeded) joins to all my queries, not to mention the extra cycles that will be necessary to perform the join on every query. Thanks for reading, appreciate comments. Ryan

  • Why Does My Website Redirect me to my localhost?

    - by Noah Brainey
    Alright, my website has some issues that I'm not sure what's causing them. Visit this page http://online-file-sharing.net/tos.html and click one of the bottom footer links... it redirects you to your localhost in the address bar. I have no idea why it does this. I'm hosting this website on my own server, which is this computer, and using Xampp. If this information helps. Anyways any help would be greatly appreciated! I'm also using DYNDNS as my nameservers. I've already ask this question on superuser and webapps QnA sites neither could help. They said to come here. Another thing to note is that this website runs on one script and not multiple scripts (upload.cgi). However there are three files that aren't dynamic and aren't part of the upload.cgi file... these are about.html, browse.html and tos.html. Another thing to note is that my homepage which is upload.cgi can only be accessed by manually typing in online-file-sharing.net/cgi-bin/upload.cgi (which isn't it's real location but it seems to recognize it this way... but redirects me to my localhost). .htaccess file code: DirectoryIndex upload.cgi My upload.cgi path code: my $version = "4.14"; $ENV{PATH} = '/bin:/usr/bin'; delete @ENV{'IFS', 'CDPATH', 'ENV', 'BASH_ENV'}; ($ENV{DOCUMENT_ROOT}) = ($ENV{DOCUMENT_ROOT} =~ /(.*)/); # untaint. #$ENV{SCRIPT_NAME} = '/cgi-bin/upload.cgi'; use lib './perlmodules'; #use Time::HiRes 'gettimeofday'; #my $hires_start = gettimeofday(); my (%PREF,%TEXT) = (); The script I'm using is FileChucker. I hope this information is enough to find an answer... if not please let me know and I'll post as much information as you need!

  • flushing database cache in SWI-Prolog

    - by JPro
    We are using swi-prolog to run our testcases. Whenever the test starts, I am opening the connection to MYSQL database and storing the Name of the Test hat is being done and then closing the DB. These tests run for about 2 days continuously. After the tests are done, the results basically gets stored in folder in the server. There is a predicate in another prolog file that is called to update the results to the MYSQL database. The code is simple, I use odbc library and just call odbc_* predicates to connect and update the mysql by issuing direct queries. The actual problem is : If I try to call the Predicate from the same Prolog window, where the test just got completed, I get an error as updating to the DB server. Although I do not get any error in the connection. If I close the session of that prolog with halt and closing all the open prolog windows , then open an other complete new instance of Prolog and run the predicate the update goes well. I have a feeling that there is some connection reference to the MySQL DB in Prolog database. Is there any way to clear the database in prolog so that I can run the same predicate without closing any existing prolog windows? Any ideas appreciated. Thanks.

  • Seperating Javascript and Html, when dynamically adding html via javascript

    - by optician
    I am currently building a very dynamic table for a list application, which will basically perform basic CRUD functions via AJAX. What I would like to do is separate the visual design and javascript to the point where I can change the design side without touching the JS side. This would only work where the design stays roughly the same(i would like to use it for rapid protyping) Here is an example. <table> <tr><td>record-123</td><td>I am line 123</td><td>delete row</td></tr> <tr><td>record-124</td><td>I am line 124</td><td>delete row</td></tr> <tr><td>record-125</td><td>I am line 125</td><td>delete row</td></tr> <tr><td>add new record</td></tr> </table> Now, when I add a new record, I would like to insert a new row of html, but I would rather not put this html into the javascript file. What I am considering is creating a row like this on the page, near the table. <tr style='visble:none;' id='template-row'><td>record-id</td><td>content-area</td><td>delete row</td></tr> And when I come to add the new row, I search the page for the tags with the id=template-row , and then grab it, do a string replace on it, and then put it in the right place in the page. As long as the design doesn't shift radically, and I keep the placeholder strings the same, it means designs can be quickly modified without touching the js. Can any give any advice on a methodology like this?

  • Resources related to data-mining and gaming on social networks

    - by darren
    Hi all I'm interested in the problem of patterning mining among players of social networking games. For example detecting cheaters of a game, given a company's user database. So far I have been following the usual recipe for a data mining project: construct a data warehouse that aggregates significant information select a classifier, and train it with a subsectio of records from the warehouse validate classifier with another test set lather, rinse, repeat Surprisingly, I've found very little in this area regarding literature, best practices, etc. I am hoping to crowdsource the information gathering problem here. Specifically what I'm looking for: What classifiers have worked will for this type of pattern mining (it seems highly temporal, users playing games, users receiving rewards, users transferring prizes etc). Are there any highly agreed upon attributes specific to social networking / gaming data? What is a practical amount of information that should be considered? One problem I've run into is data overload, where queries and data cleansing may take days to complete. Related to point above, what hardware resources are required to produce results? I've found it difficult to estimate the amount of computing power I will require for production use. It has become apparent that a white box in the corner does not have enough horse-power for such a project. Are companies generally resorting to cloud solutions? Are they buying clusters? Basically, any resources (theoretical, academic, or practical) about implementing a social networking / gaming pattern-mining program would be very much appreciated. Thanks.

  • Deleting a user > need to also delete their project, and then activities for that project? (PHP, MyS

    - by Jamie
    Hi guys, Really stuck with this... basically my system has 4 tables; users, projects, user_projects and activities. The user table has a usertype field which defines whether or not they are admin or user (by an integer)... An admin can create a project, create an acitivity for the project and assign a user (limited access user) an activity. Therefore, this setup means that an admin is never directly associated with an activity (instead a project). When my head admin user deletes an admin, I need all projects and activities (for their projects) to be deleted also. My delete script for a user is simple so far and works, but I'm having trouble on how to gain the projectID in order to know which activities to remove (associated with the projects which are about to be deleted): $userid = $_GET['userid']; $query = "DELETE FROM users WHERE userid=".$userid; $result = mysql_query($sql, $connection) or die("Error: ".mysql_error()); $query = "DELETE FROM projects WHERE userid=".$userid; $result = mysql_query($sql, $connection) or die("Error: ".mysql_error()); $query = "DELETE FROM userprojects WHERE userid=".$userid; $result = mysql_query($sql, $connection) or die("Error: ".mysql_error()); $query = "DELETE FROM activities WHERE projectid=".$projectid; $result = mysql_query($sql, $connection) or die("Error: ".mysql_error()); Now the first three queries execute fine, obviously because the userid is being retrieved successfully. However the 4th and final query I know is wrong, because there is no projectid to be gained from anywhere, however I put it there to help understand what I am trying to get!! :D Im guessing that i would need something like 'WHERE projectid=' then something to gather the removed projects from the userid which can be related to the activities for that project(s)!! Its a simple concept but I'm having trouble...please excuse any bad code as I am learning also. Thanks for any help!

  • Populating array of input fields as alternate fields using jQuery UI datepicker

    - by Micor
    I am using jquery ui datepicker in order to populate start and end dates for multiple events on the same page, the number of events is dynamic and I need to post day, month and year as separate fields, so I have something like this: <input type="text" name="event[0].startDate" class="date"/> <input type="hidden" name="event[0].startDate_day" class="startDate_day" /> <input type="hidden" name="event[0].startDate_month" class="startDate_month" /> <input type="hidden" name="event[0].startDate_year" class="startDate_year" /> <input type="text" name="event[0].endDate" class="date"/> <input type="hidden" name="event[0].endDate_day" class="endDate_day" /> <input type="hidden" name="event[0].endDate_month" class="endDate_month" /> <input type="hidden" name="event[0].endDate_year" class="startDate_year" /> event[1]... event[2]... I started working on jQuery functionality and this is what I have so far, which will populate alternate fields for startDate by class, of course it will not do what I need because I need to populate by field name rather then class: $(".date").datepicker({ onClose: function(dateText,picker) { $('.startDate_month').val( dateText.split(/\//)[0] ); $('.startDate_day').val( dateText.split(/\//)[1] ); $('.startDate_year').val( dateText.split(/\//)[2] ); }}); I need help figuring out how can I get the name of the input field within datepicker function so the alternate field assignment done by that field name + _day, month, year so this function can work for all the events on the page, making function above look more like: $(".date").datepicker({ onClose: function(dateText,picker) { $('input[' + $name + '_month' + ']').val( dateText.split(/\//)[0] ); $('input[' + $name + '_day' + ']').val( dateText.split(/\//)[1] ); $('input[' + $name + '_year' + ']').val( dateText.split(/\//)[2] ); }}); Hope that makes sense :) Thanks

  • Crawler do not create custom crawled properties

    - by user173739
    These days i have faced with very strange problem. I have development environment with MOSS 2007 SP 2 and WS 2008, i have search configured and everything works great. I have started to configuring staging environment (MOSS 2007 SP2 with June CU) and create new farm and new SSP. I have deployed my changes with package (wsp) and manually create site collections, sub webs, pages and so on. When fill crawl finishes, i see in Crawl log that all my pages have been successfully crawled and when i use some test tools to query search, my pages have been found. In crawl log there is few errors like http://mysite/sites/de/pages "The crawler could not communicate with the server. Check that the server is available and that the firewall access is configured correctly..", but all pages in this Page library were indexed. The problem is that i use custom managed properties (mapped to custom crawled properties) in search queries, but crawler didn't create crawled properties for all my new site columns. For example for site column IsAccent the crawler didn't create cralwed property ows_isAccesnt. I'm sure that i have created pages for specific content type and all my crawl categories have checked "Automatically discover new properties when a crawl takes place ". In site settings - Searchable columns i haven't got any column selected as Nocrowl. I tried to export my managed and crawled properties from dev environment to stage evironment but all my managed properties were empty, after that i recreated SSP...the result was the same... I checked specific page with tools like Sharepoint Manager 2007 and U2U Caml Query Builder 2007 that content type is correct, and i can see values of my custom site collumns.... Using U2U Caml Query Builder 2007 agains some Page library in Result tab i can see ows_IsAccent (my site collumn is IsAccent) and others site columns, but i can't find them in Crawled properties. Any idias?

  • General Web Programming/designing Question: ?

    - by Prasad
    hi, I have been in web programming for 2 years (Self taught - a biology researcher by profession). I designed a small wiki with needed functionalities and a scientific RTE - ofcourse lot is expected. I used mootools framework and AJAX extensively. I was always curious when ever I saw the query strings passed from URL. Long encrypted query string directly getting passed to the server. Especially Google's design is such. I think this is the start of providing a Web Service to a client - I guess. Now, my question is : is this a special, highly professional, efficient / advanced web design technique to communicate queries via the URL ? I always felt that direct URL based communication is faster. I tried my bit and could send a query through the URL directly. here is the link: http://sgwiki.sdsc.edu/getSGMPage.php?8 By this , the client can directly link to the desired page instead of searching and / or can automate. There are many possibilities. The next request: Can I be pointed to such technique of web programming? oops: I am sorry, If I have not been able to convey my request clearly. Prasad.

  • wpf - window to be tight round user control

    - by Andy Clarke
    Hi, I've got a user control that I'm loading into a Window dynamically - I wanted to set the Window so that it didn't have a size and then I thought the window to resize accordingly depending on the UserControl. However it dosn't - can anyone assist please? I've made a very basic example - I've cut out the dynamic bits and just put a UserControl in a Window. What do I need to do to get the window to be tight around the UserControl? Thanks, Andy <UserControl x:Class="WpfApplication1.UserControl1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="300" Width="300" Background="LightBlue"> <Grid> </Grid> </UserControl> <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:WpfApplication1="clr-namespace:WpfApplication1" Title="Window1" > <Grid> <WpfApplication1:UserControl1> </WpfApplication1:UserControl1> </Grid> </Window>

  • Entity Framework query not returning correctly enumerated results.

    - by SkippyFire
    I have this really strange problem where my entity framework query isn't enumerating correctly. The SQL Server table I'm using has a table with a Sku field, and the column is "distinct". It isn't a key, but it doesn't contain any duplicate values. Using actual SQL with where, distinct and group by cluases I have confirmed this. However, when I do this: // Not good foreach(var product in dc.Products) or // Not good foreach(var product in dc.Products.ToList()) or // Not good foreach(var product in dc.Products.OrderBy(p => p.Sku)) the first two objects that are returned ARE THE SAME!!! The third item was technically the second item in the table, but then the fourth item was the first row from the table again!!! The only solution I have found is to use the Distinct extension method, which shouldn't really do anything in this situation: // Good foreach(var product in dc.Products.ToList().Distinct()) Another weird thing about this is that the count of the resulting queries is the same!!! So whether or not the resulting enumerable has the correct results or duplicates, I always get the number of rows in the actual table! (No I don't have a limit clause anywhere). What could possibly cause this!?!?!?

  • Oracle command hangs when using view for "WHERE x IN..." subquery

    - by Calvin Fisher
    I'm working on a web service that fetches data from an oracle data source in chunks and passes it back to an indexing/search tool in XML format. I'm the C#/.NET guy, and am kind of fuzzy on parts of Oracle. Our Oracle team gave us the following script to run, and it works well: SELECT ROWID, [columns] FROM [table] WHERE ROWID IN ( SELECT ROWID FROM ( SELECT ROWID FROM [table] WHERE ROWID > '[previous_batch_last_rowid]' ORDER BY ROWID ) WHERE ROWNUM <= 10000 ) ORDER BY ROWID 10,000 rows is an arbitrary but reasonable chunk size and ROWID is sufficiently unique for our purposes to use as a UID since each indexing run hits only one table at a time. Bracketed values are filled in programmatically by the web service. Now we're going to start adding views to the indexing, each of which will union a few separate tables. Since ROWID would no longer function as a unique identifier, they added a column to the views (VIEW_UNIQUE_ID) that concatenates the ROWIDs from the component tables to construct a UID for each union. But this script does not work, even though it follows the same form as the previous one: SELECT VIEW_UNIQUE_ID, [columns] FROM [view] WHERE VIEW_UNIQUE_ID IN ( SELECT VIEW_UNIQUE_ID FROM ( SELECT VIEW_UNIQUE_ID FROM [view] WHERE ROWID > '[previous_batch_last_view_unique_id]' ORDER BY VIEW_UNIQUE_ID ) WHERE ROWNUM <= 10000 ) ORDER BY VIEW_UNIQUE_ID It hangs indefinitely with no response from the Oracle server. I've waited 20+ minutes and the SQLTools dialog box indicating a running query remains the same, with no progress or updates. I've tested each subquery independently and each works fine and takes a very short amount of time (<= 1 second), so the view itself is sound. But as soon as the inner two SELECT queries are added with "WHERE VIEW_UNIQUE_ID IN...", it hangs. Why doesn't this query work for views? In what important way are they not interchangeable here?
