  • SQLite not pluralizing Table Names

    - by weenet
    I am using SQLite as my db during development, and I want to postpone actually creating a final database until my domains are fully mapped. So I have this in my Global.asax.cs file: private void InitializeNHibernateSession() { Configuration cfg = NHibernateSession.Init( webSessionStorage, new [] { Server.MapPath("~/bin/MyNamespace.Data.dll") }, new AutoPersistenceModelGenerator().Generate(), Server.MapPath("~/NHibernate.config")); if (ConfigurationManager.AppSettings["DbGen"] == "true") { var export = new SchemaExport(cfg); export.Execute(true, true, false, NHibernateSession.Current.Connection, File.CreateText(@"DDL.sql")); } } The AutoPersistenceModelGenerator hooks up the various conventions, including a TableNameConvention like so: public void Apply(FluentNHibernate.Conventions.Instances.IClassInstance instance) { instance.Table(Inflector.Net.Inflector.Pluralize(instance.EntityType.Name)); } This is working nicely execpt that the sqlite db generated does not have pluralized table names. Any idea what I'm missing? Thanks.

  • Fluent NHibernate beginner problem: How to convert single column data to custom class?

    - by Stefan Ahlm
    I am very new to Fluent NHibernate and I have a problem that I cant find the answer to. I have a string column in my database table, containing a mathematical expression i.e: "10 + 15 * 5". On my entity I have a property that I call Formula and this returns a class that contains the mathematical "formula" (not as a string). I beleive this post http://intellect.dk/post/Implementing-custom-types-in-nHibernate.aspx explains how to solve it for NHibernate. But I am not sure... How do I get this working with Fluent NHibernate?

  • Fast exchange of data between unmanaged code and managed code

    - by vizcaynot
    Hello: Without using p/invoke, from a C++/CLI I have succeeded in integrating various methods of a DLL library from a third party built in C. One of these methods retrieves information from a database and stores it in different structures. The C++/CLI program I wrote reads those structures and stores them in a List<, which is then returned to the corresponding reading and use of an application programmed completely in C#. I understand that the double handling of data (first, filling in several structures and then, filling all of these structures into a list<) may generate an unnecessary overload, at which point I wish C++/CLI had the keyword "yield". Depending on the above scenario, do you have recommendations to avoid or reduce this overload? Thanks.

  • Filtering coluns in SQL Server replication - how?

    - by truthseeker
    Hi, I need to replicate some data from two tables in one database to another databases. I used snapshot replication. The issue is that I would like to replicate only some selected columns and the others should stay with untouched data. I don't want to loose their data. The sours of those columns is other system. So I need to replicate only data from my columns. Do anybody know how to achieve this?

  • RPC Fails but passing in SQL Man. Studios works

    - by Justin
    I am calling a stored procedure from a web service in an ASP.Net application. And until a few days ago, all was well. However now when i call it I get an error saying The timeout period elapsed prior to the completion of the operation or the server could not be reached. However when i would run SQL SERVER PROFILER, I could see that the call was getting to the database, but was timing out. I then copied the statement being executed found at the bottom of the Profiler and pasted it into Management Studio and executed it and it finishes in about 7 seconds.. This runs just fine on our production server. It seems to be similar to this question: SELECT DISTINCT not working in .NET application, but works in SQL Mgmt Studio but I see no answer.

  • NSArray vs. SQLite for Complex Queries on iPhone

    - by GingerBreadMane
    Developing for iPhone, I have a collection of points that I need to make complex queries on. For example: "How many points have a y-coordinate of 10" and "Return all points with an X-coordinate between 3 and 5 and a y-coordinate of 7". Currently, I am just cycling through each element of an NSArray and checking to see if each element matches my query. It's a pain to write the queries though. SQLite would be much nicer. I'm not sure which would be more efficient though since a SQLite database resides on disk and not in memory (to my understanding). Would SQLite be as efficient or more efficient here? Or is there a better way to do it other than these methods that I haven't thought of? I would need to perform the multiple queries with multiple sets of points thousands of times, so the best performance is important.

  • Overwrite queryset which builds filter sidebar

    - by cw
    Hi, I'm writing a hockey database/manager. So I have the following models: class Team(models.Model): name = models.CharField(max_length=60) class Game(models.Model): home_team = models.ForeignKey(Team,related_name='home_team') away_team = models.ForeignKey(Team,related_name='away_team') class SeasonStats(models.Model): team = models.ForeignKey(Team) Ok, so my problem is the following. There are a lot of teams, but Stats are just managed for my Club. So if I use "list_display" in the admin backend, I'd like to modify/overwrite the queryset which builds the sidebar for filtering, to just display our home teams as a filter option. Is this somehow possible in Django? I already made a custom form like this class SeasonPlayerStatsAdminForm(forms.ModelForm): team = forms.ModelChoiceField(Team.objects.filter(club__home=True)) So now just the filtering is missing. Any ideas?

    Get data from html form to ruby in Ruby on Rails I have some html like this <html> <h1>Text to PDF</h1> <textarea name="comments" cols="40" rows="5"> Enter your Text here... </textarea><br> <input type="submit" value="Submit" /> </form> </body> </html> I want to give the value of the text into the controller for this page/view. How do I do this with rails? I am new to rails, what is the mechanism for this? I don't need to write to the database just want to hand it to the controller. If there is a good tutorial for this sort of thing that would be great, I am not convince I am approaching this correctly.

  • Recommendations for C# controls that can be used to create a hierarchical list of prioritised items?

    - by Mendokusai
    I need to be able to display and edit a hierarchical list of tasks in a C# app. It can either be a Windows form app, or ASP.NET. Basically, I want similar behaviour to the way Microsoft Project handles tasks. The control would need to: 1) Maintain a list of items made up of several fields 2) Each item can have a number of children (at least 3 levels of nesting) 3) It needs to be very easy to change the parents/children of an item 4) It needs to be very easy to edit the fields (as fast as changing cells in Excel) 5) It needs to be very easy to reorder the items by dragging and dropping or cut and paste 6) If I can easily connect the control to a database, even better Anyone got any recommendations for controls for me to look at?

  • Why is rails setting ":null => false" on all my columns in schema.rb?

    - by ryeguy
    Even if I never specify :null => false in my migrations that initially add columns to tables, rails still generates code in schema.rb that specifies the columns as having :null => false. Why is this? If I develop on my box, and then use rake db:schema:load on my production box, I'm going to get very different behavior! Edit: Even if I delete schema.rb and run rake db:schema:dump, it still puts :null => false on the new schema even if it isn't defined like that in the actual database. It seems it can't tell whether or not a column is marked as allowing nulls. I'm using SQLite if that helps.

  • Mysql: how to generate count table by PATTERN / LIKE statement ? very tricky

    - by Abdulrahman Al-Qabandi
    to simplify, I got a database of registered users, I want to count how many emails there are for each email domain name (note I do not know all domain names) for example, Users table- id | email ------------------ 1 | [email protected] 2 | [email protected]<--unknown to me 3 | [email protected]<--unknown to me 4 | [email protected] 5 | [email protected]<--unknown to me 6 | [email protected] 7 | [email protected] 8 | [email protected] ( note: I want to count each email without specifying which email exactly ) so the result I want is suffix | count hotmail.com | 3 somesite.aaa | 2 unknownsite.aaa| 1 yahoo.com | 2 again, I stress this, I do not know unknownsite.aaa nor can i mention it in a statement because it is unknown to me, i hope I am clear. So essentially I want to make a statistic of what my website users use as an email host website. but like I said and I will repeat the third time, I do not know every mailhost that exists. I am going to investigate this more, I have a feeling this is something mysql cannot handle.

  • MySQL searching using many 'like' operators: is there a better way?

    - by DrAgonmoray
    I have a page that gets all rows from a table in a database, then displays the rows in an HTML table. That works great, but now I want to implement a 'search' feature. There is a searchbox, and search-terms are separated by a space. I am going to make it search three fields for the search terms, 'make' 'model' and 'type.' These three fields are VARCHAR(30). Currently if I wanted to search using 3 terms (say 'cool' 'abc' and '123') my query would look something like this. SELECT * FROM table WHERE make LIKE '%cool%' OR make LIKE '%abc%' OR make LIKE '%123%' OR model LIKE '%cool%' OR model LIKE '%abc%' OR model LIKE '%123%' OR type LIKE '%cool%' OR type LIKE '%abc%' OR type LIKE '%123%' That looks really bad, and it will get even worse if there are more search terms or more fields to search. My question to you: is there a better way to search? If so, what?

  • Relogging a user in with different Spring Security Authorities programmatically

    - by user1331982
    PreReq: User logs in and is given roles got from the database using a custom implementation of userService. i.e. authentication-provider user-service-ref="securityPolicyService" The implemented method loadUserByUsername gets called and the roles are load for the user for the particular club they are logging into, Default one is loaded first time in. The user then click on a different club from the UI and I call a method on a service that gets the new list of authorities for this club. I then perform the following: Object principle = SecurityContextHolder.getContext().getAuthentication().getPrincipal(); SecureMember sm = (SecureMember) principle; Authentication auth = new UsernamePasswordAuthenticationToken(sm, null, newAuthories); <br><br> SecurityContextHolder.getContext().setAuthentication(auth);<br> request.getSession(false).invalidate(); SecureMember extends User from SpringFramework. The problem is the SecureMember authorities are never updated with the new ones. thanks Gary

  • Update JSON file C# W8 development

    - by AndrewB
    At the moment, I've got a JSON file with content looking like this: { "username": "test", "someNumber":100 } I'm using JSON.Net to fetch the .JSON file from a webserver - C#: var http = new HttpClient(); http.MaxResponseContentBufferSize = Int32.MaxValue; var response = await http.GetStringAsync(URI); var result = JsonConvert.DeserializeObject<DatClass.Result>(response); This works great together with the class getting/setting the properties. However, what I would like to know is whether there's a good way for a user to update the .JSON file through a textbox UI? As in: [textbox - update username] [update button] - username sent to server - .JSON file updated - [textblock - showing updated username in UI]. I'm not looking for exact code solutions, I'm rather looking for good solutions on this, and/or if this is a terrible idea of an easy database(?).

  • How to store user-specific data in SharePoint

    - by Paul-Jan
    I have some user-specific data that I need to store in SharePoint and make accessible to the user through custom webparts. Let's say a list of favorite URLs. What would be the most straightforward way to store this information? Some builtin propertybag for SPUser or similar that I'm not aware of. SPList, associated through User column. Custom database table, associated through SPUser ID. Otherwise? Sounds like a RTFM to me, but I'm probably asking google the wrong questions.

  • PHP session values lost after redirect on one script but preserved after redirection on another.

    - by Iuhiz
    On my registration script i have: // Save registration information into the database // Set sessions $_SESSION['var1'] = 'somevalue'; $_SESSION['var2'] = 'anothervalue'; header('Location: /somewhere'); exit(); Then on my login script i have: // Check if user provided correct login credentials if (correct) { $_SESSION['var1'] = 'somevalue'; $_SESSION['var2'] = 'anothervalue'; } header('Location: /somewhere'); exit(); What happened is that the session variables were lost after the header redirect in the registration script but they were preserved after the redirect in the login script. I've checked session_id() at both pages and they have the same value, included session_start() at the top of every page and basically tried the solutions to this common problem found on Stackoverflow but somehow nothing seemed to work. I'm beginning to wonder if it is something to do with my server configuration instead of my code.

  • Best way to collect and store data daily?

    - by mktb
    I have a bunch of statistics: # of users, # of families, ratio user/family, etc. I'd like to store these daily so I can view this data historically. However, I'm looking for the most effective way to store this data. Should I run a cron job that writes to the database DATE: today USERS: 123 FAMILIES: 456 RATIO: 7.89 or whatever? (or should I write multiple rows like DATE: today DATATYPE: users VALUE: 123?) Or is there another option I can use that is more efficient or more effective? Thanks!

  • PHP MySQL New Lines / Whitespaces from textarea

    - by rob_robsen
    I've a problem about whitespaces and new lines at the beginning of a textarea. I send a json string with ajax to the php script. Then I decode the string into an php array (with json_decode). So I have a string in this array with two line breaks at the beginning. If a print the text from the array, the line breaks are there, but if I store the text into the mysql database, the line breaks are gone... Only at the beginning of the string, the line breaks gone... At the rest of the string, the line breaks are ok. Thanks for your answers! rob

  • Using ActiveRecord::Base.transaction in a rake task?

You might have expected an instance of ActiveRecord::Base. The error occurred while evaluating nil.[] The stack trace points to the aforementioned line in the code. Is there a way to instantiate ActiveRecord::Base during a rake task? Thanks!

  • Is there a way to give a subquery an alias in Oracle 11g SQL?

    - by Matt Pascoe
    Is there a way to give a subquery in Oracle 11g an alias like: select * from (select client_ref_id, request from some_table where message_type = 1) abc, (select client_ref_id, response from some_table where message_type = 2) defg where abc.client_ref_id = def.client_ref_id; Otherwise is there a way to join the two subqueries based on the client_ref_id. I realize there is a self join, but on the database I am running on a self join can take up to 5 min to complete (there is some extra logic in the actual query I am running but I have determined the self join is what is causing the issue). The individual subqueries only take a few seconds to complete by them selves. The self join query looks something like: select st.request, st1.request from some_table st, some_table st1 where st.client_ref_id = st1.client_ref_id;
