This question already has an answer here: Getting data from stored procedure with Entity Framework 4 answers Environment: Visual Studio 2017 SQL Server 2016 EF v6 with a database-first approach Background: the stored procedure is in the EDMX. My stored procedure sets the return value to 0 if nothing happened, 1 if something affected and value of @@ERROR if errors. BACKGROUND 1: my stored procedure, LTM_Lease_DeleteSubFiles , does SET NOCOUNT ON at the top and sets return value with RETURN command at the end of the stored procedure. PROBLEM 1: my call returns -1 which is not even in the stored

I would like to know how to find a List<Object> using Find method of Entity Framework passing Array( object[] ) as parameter? I want to find all data by Primary Key. I first fill a list with all PK that I will use as reference: List<int> lCodigoServicos = new List<int>(); foreach (ServicosSelecionadosModelView servicoSelecionado in lServicos.FindAll(s => !string.IsNullOrEmpty(s.selecionado) && s.selecionado.ToLower() == "on" )) lCodigoServicos.Add(servicoSelecionado.servico.SerId); After fill my list of PK, I try find all data by PK var lServicosInformados = db.Servicos.Find(lCodigoServicos

I know that a very similar question has been asked here , but the answer didn't help me. I am using Entity Framework 6 with the Oracle.ManagerDataAccess.Client. If I define the connection string in app.config, then the connection works. If I specify the identical connection string in code, then I get the error The value's length for key 'data source' exceeds it's limit of '128'. which is correct. This is my connection string (with some names removed): "User Id=xxxxxxxxxxx;Password=xxxx;Data Source=( DESCRIPTION = ( ADDRESS_LIST = ( ADDRESS = (PROTOCOL = TCP)(HOST = VS-ORACLE.xxxxxxx.de)(PORT =

I am building a C# Web API using Entity Framework 6.0. I have the simplest User Class with 3 properties that I persist on SQL into a User Table with 3 corresponding columns where UserID is its the Primary Key. public partial class User { public string UserID {get; set;} public string FirstName {get; set;} public string LastName {get; set;} } I want to add to the Web API two output-only properties on the fly that I do not care to store in my DB. I use these properties to communicate to the consuming client "Status" and "Message" information that are not part of the User Class. Status = OK|Error

I am trying to use EF to export/import the existing database of a DbContext. In this context, there are several entities with Guid Id properties with DatabaseGeneratedOption.Identity defined by the ModelBuilder. When I re-import the entities, I want to use the Id value from the serialized object, but it always generates a new Id value when I save the changes. Is there any way to force EF to use my Id value in this case? I know DatabaseGeneratedOption.None will allow me to do it, but then I will always be responsible for generating the Id. I know there segmentation issues of the index that

I just encountered a weird bug in my app where a paged data grid contained duplicate rows. Investigation showed that it's because the new paging mechanism Entity Framework uses with Sql Server 2012 as of version 6.1.2 only works on strictly ordered column sets , as is documented here . Since most columns are not strictly ordered (meaning you have duplicate entries with respect to the sort order), simply binding one of the typical grid middlewares to Entity Framework is now broken subtly and horribly. I can't believe I'm the first to complain, but I did google! I found at least a dba

OK, Google, I am not able to googling it. Documentation says The model for that context is then cached and is for all further instances of the context in the app domain. This caching can be disabled by setting the ModelCaching property on the given ModelBuidler and SO confirms it. But i can't find way to do it. I have to disable caching because i want to get data from several log table with same structure via just one model, so my code looks like logTableNames.ForEach(n => { using (var context = new LogContext(n)) { Console.WriteLine($"Project: {n} -- {context.Logs.Count()} rows.\n"); } });
