Question

I have a stored procedure that returns a table (or dataset or view or whatever it’s called, it returns the result of a select). I use entity framework and I’d expect it to treat the stored proc like a table by creating an entity. When I add the proc to the entity schema, it’s added but no class is generated (nothing appears on the schema or in the intellisense).

I do not want to use this dataset solution that looks ugly and unoptimised:

SqlCommand sqlCommand = new SqlCommand("sp_ProjetsVoxco");
sqlCommand.CommandType = CommandType.StoredProcedure;
sqlCommand.Connection = new SqlConnection(
    Settings.Default.ConnectionStringTransit);
SqlDataAdapter sa = new SqlDataAdapter(sqlCommand);
DataSet dataSet = new DataSet();
sa.Fill(dataSet);

I’ve found a line that seems to be very neat:

var x = context.ExecuteStoreQuery<T>("sp_ProjetsVoxco");

But since entity framework did not generate a class, I’m not really sure what to do with the T.

Answer 1

I’ll assume that you have your edmx file and you are now trying to add a Store Procedure that you already have created in the Database.

1 – You should add your Store Procedure that by adding it just like any other table using the Update Model from database option, this will make EF to know about a SP. (Because I already have my SP I’m showing the Refresh tab, but you will see your SP’s in Add tab if you didn’t add them yet)

2 – Import a function

3 – Give it a name and create a new Complex Type

4 – Click OK and use the new method name

public IEnumerable<mySPMethodCallName_Result> ListAllServiceLogsFromSP(decimal clientId)
{
    var r = from sp in db.sp_ListServiceLogsByClientId(clientId)
            select sp;

    return r;
}
