EF 4.xx and storage procedure

In EF 4.xx operatiile de tip CRUD sutn foarte usor de executat. Dar ce se intampla daca avem nevoie sa executam o procedura stocata. De exemplu dorim sa populam un tabel, iar pentru acest lucru trebuie sa rulam o proceduta stocata.
Pentru acest lucru avem doua posibitati.
Prima din ele este sa ne cream un obiect de tip SqlQuery care poate sa contina orice comanda sql, iar apoi sa il executam.
DataContext.Database
      .SqlQuery<int>("EXEC PopulateTable @param1 @param2",
            new SqlParameter("param1", "100"),
            new SqlParameter("param2", "1/12/2011"));
Aceasta modalitate este perfecta cand stocata/comanda pe care o executam ne returneaza date. Cand folosim aceasta comanda, data context stie ca datele au fost modificate.
In cazul in care comanda pe care o executam nu ne returneaza valori si nu ne intereaza ca data contextul sa fie aware ca datele au fost modificate putem sa folosim comanda
ExecuteSqlCommand.DataContext.Database
      .ExecuteSqlCommand("EXEC PopulateTable @param1 @param2",
            new SqlParameter("param1", "100"),
            new SqlParameter("param2", "1/12/2011"));
Data contextul o sa stie de modificari doar cand o facem reload la date.
Daca folosim EF 4.xx si Code-First aceasta este singura posibilitate sa executam proceduri stocate.

ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded

Today blog post will be started with the following error when running DB tests on the CI machine:
threw exception: System.InvalidOperationException: The Entity Framework provider type 'System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer' registered in the application config file for the ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded. Make sure that the assembly-qualified name is used and that the assembly is available to the running application. See http://go.microsoft.com/fwlink/?LinkId=260882 for more information. at System.Data.Entity.Infrastructure.DependencyResolution.ProviderServicesFactory.GetInstance(String providerTypeName, String providerInvariantName) This error happened only on the Continuous Integration machine. On the devs machines, everything has fine. The classic problem – on my machine it’s working. The CI has the following configuration:

Entity Framework (EF) TransactionScope vs Database.BeginTransaction

In today blog post we will talk a little about a new feature that is available on EF6+ related to Transactions.
Until now, when we had to use transaction we used ‘TransactionScope’. It works great and I would say that is something that is now in our blood.
using (var scope = new TransactionScope(TransactionScopeOption.Required)) { using (SqlConnection conn = new SqlConnection("...")) { conn.Open(); SqlCommand sqlCommand = new SqlCommand(); sqlCommand.Connection = conn; sqlCommand.CommandText = ... sqlCommand.ExecuteNonQuery(); ... } scope.Complete(); } Starting with EF6.0 we have a new way to work with transactions. The new approach is based on Database.BeginTransaction(), Database.Rollback(), Database.Commit(). Yes, no more TransactionScope.
In the followi…

GET call of REST API that contains '/'-slash character in the value of a parameter

Let’s assume that we have the following scenario: I have a public HTTP endpoint and I need to post some content using GET command. One of the parameters contains special characters like “\” and “/”. If the endpoint is an ApiController than you may have problems if you encode the parameter using the http encoder.
using (var httpClient = new HttpClient()) { httpClient.BaseAddress = baseUrl; Task<HttpResponseMessage> response = httpClient.GetAsync(string.Format("api/foo/{0}", "qwert/qwerqwer"))); response.Wait(); response.Result.EnsureSuccessStatusCode(); } One possible solution would be to encode the query parameter using UrlTokenEncode method of HttpServerUtility class and GetBytes method ofUTF8. In this way you would get the array of bytes of the parameter and encode them as a url token.
The following code show to you how you could write the encode and decode methods.
