• SimpleRepository auto migrations with indexes

  - by scott

  I am using subsonic simplerepo with migrations in dev and it makes things pretty easy but I keep running into issues with my nvarchar columns that have an index. My users table has an index defined on the username column for obvious reasons but each time I start the project subsonic is doing this: ALTER TABLE [Users] ALTER COLUMN Username nvarchar(50); which causes this: The index 'IX_Username' is dependent on column 'Username'.ALTER TABLE ALTER COLUMN Username failed because one or more objects access this column Is there any way around this issue?

• Lambda Contains in SimpleRepository.Find

  - by Anton

  In SubSonic 3.04's SimpleRepository, I cannot seem to perform a Contains operation within a lambda expression. Here's a trivial example: SimpleRepository repo = new SimpleRepository("ConnectionString"); List<int> userIds = new List<int>(); userIds.Add(1); userIds.Add(3); List<User> users = repo.Find<User>(x => userIds.Contains(x.Id)).ToList(); I get the error message: variable 'x' of type 'User' referenced from scope '', but it is not defined Am I missing something here, or does SubSonic not support Contains in lambda expressions? If not, how would this be done?

• How do I use SimpleRepository without the migration approach?

  - by Bill Sempf

  I am evaluating SubSonic for use in Phase 2 of a large project. This is an ASP.NET project, with 700 tables in a SQL Server database. We are planning for our domain model to consist of POCO classes to assist with an offline access requirements we have. I believe that the SimpleRepository pattern would be among my best options. Since I have a database already, however, the migration assistance doesn't help me. Are there T4 templates for SimpleRepository that I just overlooked? How do I 'turn off' migration? If I missed something in the Wiki, point me there, otherwise get me started and I'll write up a Wiki entry for y'all when we get there.

• Subsonic 3, SimpleRepository, SQL Server: How to find rows with a null field?

  - by desautelsj

  How ca I use Subsonic's Find<T> method to search for rows with a field containing the "null" value. For the sake of the discussion, let's assume I have a c# class called "Visit" which contains a nullable DateTime field called "SynchronizedOn" and also let's assume that the Subsonic migration has created the corresponding "Visits" table and the "SynchronizedOn" field. If I was to write the SQL query myself, I would write something like: SELECT * FROM Visits WHERE SynchronizedOn IS NULL When I use the following code: var visits = myRepository.Find<Visit>(x => x.SynchronizedOn == null); Subsonic turns it into the following SQL query: SELECT * FROM Visits WHERE SynchronizedOn == null which never returns any rows. I tried the following code but it throws an error: visits = repository.Find<Visit>(x => x.SynchronizedOn.HasValue); I was able to use the following syntax: var query = from v in repository.All<Visit>() where v.SynchronizedOn == null orderby v.CreatedOn select v; visits = query.ToList<Visit>(); but it's not as nice an short as using the Find<T> method. Anyone knows how I can specify the "SynchronizedOn IS NULL" condition in the Find<T> method?

• Subsonic linq using activerecord very slow compared to simplerepository

  - by skiik

  Anyone know anything about why linq queries are about 6 times slower when querying using active record vs simplerepository? The below code runs 6 times slower than when i query the data using a simple repository. This code is executed 1000 times in a loop Thanks in advance string ret = ""; // if (plan == null) { plan =VOUCHER_PLAN.SingleOrDefault(x => x.TENDER_TYPE == tenderType); } if (plan == null) throw new InvalidOperationException("voucher type does not exist." + tenderType); seq = plan.VOUCHER_SEQUENCES.First(); int i = seq.CURRENT_NUMBER; seq.CURRENT_NUMBER += seq.STEP; seq.Save();

• Subsonic Simple Repo for high volume site

  - by kjgilla

  Simple Repo has given me a competitive edge in my consulting. I can finish projects much faster than I could in the "cmd.Parameters.Add(param)" days. As things progress on this end im getting into higher volume sites and wondering if Simple Repo is still the way to go. Im wondering what people's experiences have been putting SR into production vs. NHibernate. Any tips or tricks for using SR in production.

• how to implement unitofwork pattern when using subsonic 2.1(Repository pattern) ?

  - by ROHITH

  I am using subsonic repository pattern(2.1) for asp.net mvc application.In my application,there are many repositories like categoryRepository,Blogrepository etc.Inside each of this repository i am calling subsonic's DB.Select().From()...ExecuteReader() and then loading domain objects from those reader. In the controller action i make multiple calls from these repositories for e.g. List<IBlog> blogs=_blogRepository.GetHottestBlogs(); List<ICategory> categories=_categoryRepository.GetAll(); do i have to implement any unitofwork pattern for this ?.My doubt is that how subsonic performs each operation DB.Update/Insert/Select .Is a TransactionScope is enough for batch update or do i have to use SharedDbConnectionScope to get better performance?

• How to handle request-wise DB transactions in ASP.NET MVC?

  - by Dario Solera

  I'm using SubSonic 3.0 (SimpleRepository) to handle database access in my ASP.NET MVC 1.0 application. It would be nice to handle a transaction for every web request, committing if everything went smooth and rolling back in case of exception. Is this possible? If so, how? I know this topic has been discussed many times, but I just couldn't find a satisfactory answer. I have built my own solution (create a TransactionScope in the controller, then commit/rollback in OnActionExecuted), but it turns out to be very unreliable.

• SubSonic 3.0 Simple Repository Adding a DateTime Property To An Object

  - by Blounty

  I am trying out SubSonic to see if it is viable to use on production projects. I seem to have stumbled upon an issue whith regards to updating the database with default values (String and DateTime) when a new column is created. If a new property of DateTime or String is added to an object. public class Bug { public int BugId { get; set; } public string Title { get; set; } public string Overview { get; set; } public DateTime TrackedDate { get; set; } public DateTime RemovedDate { get; set; } } When the code to add that type of object to the database is run var repository = new SimpleRepository(SimpleRepositoryOptions.RunMigrations); repository.Add(new Bug() { Title = "A Bug", Overview = "An Overview", TrackedDate = DateTime.Now }); it creates the following sql: UPDATE Bugs SET RemovedDate=''01/01/1900 00:00:00'' For some reason it is adding double 2 single quotes to each end of the string or DateTime. This is causing the following error: System.Data.SqlClient.SqlException - Incorrect syntax near '01' I am connecting to SQL Server 2005 Any help would be appreicated as apart from this issue i am finding SubSonic to be a great product. I have created a screen cast of my error here:
