  • Generated queries contain schema and catalog name

    - by stacker
    I've the same problem as described here In the generated SQL Informix expects catalog:schema.table but what's actually generated is catalog.schema.table which leads to a syntax error. Setting: hibernate.default_catalog= hibernate.default_schema= had no effect. I even removed schema and catalog from the table annotation, this caused a different issues : the query looked like that ..table same for setting catalog and schema to an empty string. Versions seam 2.1.2 Hibernate Annotations 3.3.1.GA.CP01 Hibernate 3.2.4.sp1.cp08 Hibernate EntityManager 3.3.2.GAhibernate Jboss 4.3 (similar to 4.2.3)

  • Recommended way to perform Lucene search without limit

    - by Thomas
    The Lucene documents tell me that "Hits" will be removed from the API in Lucene 3.0. Deprecated. Hits will be removed in Lucene 3.0. Use search(Query, Filter, int) instead. The proposed overload limits the number of documents returned to the value of the int. So my question is: what is the recommended way to perform a search in Lucene with no limit on the number of documents to be returned?

Each row in 'Employee' can have zero or many rows in 'EmployeeTypes' and I want to make an SQL Query that returns data of all Employees and each employee row should contain its related data in 'EmployeeTypes' (for example column called 'TypeID') as a comma separated list, like this: Meco Beco --- 45 ---- 1,2,3

  • Release management with a distributed version control system

    - by See Sharp Cheddar
    We're considering a switch from SVN to a distributed VCS at my workplace. I'm familiar with all the reasons for wanting to using a DVCS for day-to-day development: local version control, easier branching and merging, etc., but I haven't seen that much that's compelling in terms of managing software releases. Here's our release process: Discover what changes are available for merging. Run a query to find the defects/tickets associated with these changes. Filter out changes associated with "open" tickets. In our environment, tickets must be in a closed state in order to merged with a release branch. Filter out changes we don't want in the release branch. We are very conservative when it comes to merging changes. If a change isn't absolutely necessary, it doesn't get merged. Merge available changes, preferably in chronological order. We group changes together if they're associated with the same ticket. Block unwanted changes from the release branch (svnmerge block) so we don't have to deal with them again. Sometimes we can be juggling 3-5 different milestones at a time. Some milestones have very different constraints, and the block list can get quite long. I've been messing around with git, mercurial and plastic, and as far as I can tell none of them address this model very well. It seems like they would work very well when you have only one product you're releasing, but I can't imagine using them for juggling multiple, very different products from the same codebase. For example, cherry-picking seems to be an afterthought in mercurial. (You have to use the 'transplant' command). After you cherry-pick a change into a branch it still shows up as an available integration. Cherry-picking breaks the mercurial way of working. DVCS seems to be better suited for feature branches. There's no need for cherry-picking if you merge directly from a feature branch to trunk and the release branch. But who wants to do all that merging all the time? And how do you query for what's available to merge? And how do you make sure all the changes in a feature branch belong together? It sounds like total chaos. I'm torn because the coder in me wants DVCS for day-to-day work. I really want it. But I fear the day when I have to put the release manager hat and sort out what needs to be merged and what doesn't. I want to write code, I don't want to be a merge monkey.

  • Self Authenticating Links in Django

    - by awolf
    In my web app I would like to be able to email self-authenticating links to users. These links will contain a unique token (uuid). When they click the link the token being present in the query string will be enough to authenticate them and they won't have to enter their username and password. What's the best way to do this?

  • What is the best way to implement multilingual domain objects using NHibernate?

    - by Amitabh
    I have found few links but could not decide which one is the best way. http://fabiomaulo.blogspot.com/2009/06/localized-property-with-nhibernate.html (This stores all localised language data in one field. Can be a problem if we query from Sql) http://ayende.com/Blog/archive/2006/12/26/LocalizingNHibernateContextualParameters.aspx (This one has a warning at the beginning that it is a hack and no longer supported) http://www.webdevbros.net/2009/06/24/create-a-multi-languaged-domain-model-with-nhibernate-and-c/ (This does not describe how multilingual data will be structured in the database.)

  • Problem Executing Async Web Request

    - by davidhayes
    Hi Can anyone tell me what I've done wrong with this simple code? When I run it it hangs on using (Stream postStream = request.EndGetRequestStream(asynchronousResult)) If I comment out the requestState.Wait.WaitOne(); line the code executes correctly but obviously doesn't wait for the response. I'm guessing the the call to EndGetRequestStream is somehow returning me to the context of the main thread?? I'm pretty sure my code is essentially the same as the sample though (MSDN Documentation) using System; using System.Net; using System.Windows; using System.Windows.Controls; using System.Windows.Documents; using System.Windows.Ink; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Animation; using System.Windows.Shapes; using System.IO; using System.Text; namespace SBRemoteClient { public class JSONClient { public string ExecuteJSONQuery(string url, string query) { System.Uri uri = new Uri(url); HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri); request.Method = "POST"; request.Accept = "application/json"; byte[] requestBytes = Encoding.UTF8.GetBytes(query); RequestState requestState = new RequestState(request, requestBytes); IAsyncResult resultRequest = request.BeginGetRequestStream(new AsyncCallback(GetRequestStreamCallback), requestState); requestState.Wait.WaitOne(); IAsyncResult resultResponse = (IAsyncResult)request.BeginGetResponse(new AsyncCallback(GetResponseStreamCallback), requestState); requestState.Wait.WaitOne(); return requestState.Response; } private static void GetRequestStreamCallback(IAsyncResult asynchronousResult) { try { RequestState requestState = (RequestState)asynchronousResult.AsyncState; HttpWebRequest request = requestState.Request; using (Stream postStream = request.EndGetRequestStream(asynchronousResult)) { postStream.Write(requestState.RequestBytes, 0, requestState.RequestBytes.Length); } requestState.Wait.Set(); } catch (Exception e) { Console.Out.WriteLine(e); } } private static void GetResponseStreamCallback(IAsyncResult asynchronousResult) { RequestState requestState = (RequestState)asynchronousResult.AsyncState; HttpWebRequest request = requestState.Request; using (HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(asynchronousResult)) { using (Stream responseStream = response.GetResponseStream()) { using (StreamReader streamRead = new StreamReader(responseStream)) { requestState.Response = streamRead.ReadToEnd(); requestState.Wait.Set(); } } } } } }

  • Between/Timerange LINQ

    - by dezza
    My intention here is to select all entries (Bookings) between "begin" (begin_prefix) and "end" (end_prefix) BUT! The important thing is: If I have a booking at 07:25-10:00 - you query for 09:00-10:00 it should still show the booking because it reserves the room until 10 no matter what .. So .. 07.25-10.00 booking means query for 09:00-10.00 still returns a list of bookings within 09:00-10.00 (which means 07.25-10.00 is included) public static List<booking> Today(DateTime begin, DateTime end) { try { IFormatProvider Culturez = new CultureInfo(ConfigurationManager.AppSettings["locale"].ToString(), true); DateTime begin_prefix = DateTime.ParseExact(begin.ToString(), "dd-MM-yyyy HH:mm:ss", Culturez); DateTime end_prefix = DateTime.ParseExact(end.ToString(), "dd-MM-yyyy HH:mm:ss", Culturez); dbDataContext db = new dbDataContext(); // gives bookings BEFORE begin_prefix (why?) IQueryable<booking> bQ = from b in db.bookings where begin_prefix >= b.Starts && b.Ends <= end_prefix && b.Ends > b.Starts && b.pointsbookings.Count > 0 select b; // ^gives bookings BEFORE begin_prefix (why?) List<booking> bL = bQ.ToList(); return bL; } catch (Exception) { throw; } } I've tried getting this right for some time now .. Seems everytime I correct it to something new, a new overlap or selection outside the two begin/end dates seem to appear :( UPDATE CRITERIA and SOURCE: Bookings has to be WITHIN "begin_prefix" and "end_prefix" or on the exact same time .. .. currently the above code gives me bookings BEFORE begin_prefix date, which is not intentioned! We're in 2011, I got bookings from 2010 as well! ** NEW!! UPDATED: This is what I have: SEARCH.START = BOOKING.START BOOKING.END <= SEARCH.END ... the problem comes up when .. BOOKING entry: 10:00(Start)-14:00(End) This means according to above: 08.59 = 10.00 (SEARCH.START = BOOKING.START) It will never include it. But it should, since this is the same room and the seats are booked individually!

  • Visual Basic 6 ADO Update question...

    - by Dave
    Hi, I've been working with a Legacy application which interacts with a database through ADODB, and most of the changes to records follow a fairly straightforward pattern of: Create a Recordset from a query Make various change to the recordset call .Update on the recordset. What I'm wondering is, with ADODB recordsets, is there anyway to extract the 'changes'. The logic which changes the recordset is scattered about, and all I need is the changes, not how it was changed... Any suggestions for tracking changes in a recordset (in code, a trigger on the DB or similar is no use here) Thanks in advance

  • What was the most refreshingly honest non-technical comment you saw?

    - by DVK
    OK, so we all saw the lists of "funny" or "bad" comments. However, today, when maintaining an old stored procedure, I stumbled upon a comment which I couldn't classify other than "refreshingly brutally honest", left by a previous maintainer around a really freakish (both performance and readability-wise) page-long query: -- Feel free to optimize this if you can understand what it means So, in the first (and hopefully only) poll type question in my history of Stack Overflow, I'd like to hear some other "refreshingly brutally honest" code comments you encountered or written.
